Pan Granulation sludge

Steps of sludge biological fertilizer production process

1. The treated sludge (domestic sludge, industrial sludge, etc.), proper amount of qualified raw materials such as nitrogen, phosphorus, potassium, filler, etc. are sent to the raw material mixer in proportion to mix evenly.

2. Transfer to the disc feeder and add the evenly mixed material to the rotating disc of the pan fertilizer granulator through the continuous rotation of the disc. Go here for more details in auxiliary machine: 

3. The treated microbial strains are sprinkled on the disc material through the liquid component distributor of the pan fertilizer granulator, so that each particle is coated with microbial strains from the inside to the outside. The rotating disk and its edge have friction and centrifugal effect on the material, and the powder gradually gathers into the sphere. Due to the difference of particle mass, the gravity and centrifugation are different. When gravity and centrifugation increase enough to overcome friction between particles, they are thrown out of the disk, and smaller particles remain in the circle. Fine powder continues to accumulate in the dish.

4. The fertilizer is transported to the biological fertilizer dryer, and the initial drying of the fertilizer is completed by using the large airflow generated by the fan and the low-temperature hot air. Due to the species, the drying temperature is strictly controlled, and the drying temperature is lower than the survival temperature of the species.

5. Transport to the thermal screening separation particles and return the fine particles directly to the disc feeder as the core continues to participate in adhesion of the particles to the ball.

6. Transfer to the secondary biological fertilizer dryer to make full use of the high air volume and micro heat to dry bacterial fertilizer.

7. Transfer organic fertilizer cooler to cooling fertilizer by natural or forced cold air.

8. Transfer to finished product screening machine. The large particles are crushed by the crusher and returned to the disc homogenizer to continue to participate in the ball.

9. A small amount of microorganisms and bacteria are lost on the surface of the particles passing through the dryer, and the microbial species on the surface of the particles are supplemented by the coating machine. 

10. Transfer to automatic packing scale for weighing, packaging and storage.

11. The drying, cooling and workshop dust are treated by cyclone dust collector, dust removal room and wet washing to meet the standard and empty.

Bio Fertilizer Making Tech

There are many kinds of organic fertilizer, among which bio organic fertilizer is the leader. Biological fertilizer is a kind of fertilizer with the function of microbial fertilizer and organic fertilizer. It is composed of specific functional microorganisms and organic materials. It is mainly used for automatic plant residues (such as animal manure, crop straw, etc.), which are treated by harmless treatment and decomposition of organic materials. It is different from organic fertilizer produced only by natural fermentation (decomposition).

Bio Fertilizer Production

Biological organic fertilizer products not only contain high organic matter, but also contain microorganisms with specific functions, which are the basic characteristics of organic fertilizer products. In addition, the microorganisms in soil have certain fertilizer functions, such as improving soil fertility, producing and assisting crops to absorb nutrients, activating insoluble compounds in soil to absorb and utilize crops, or producing various active substances and disease resistant substances, so as to stimulate and regulate the growth of crops. It can reduce or reduce the occurrence of crop diseases and insect pests and improve the quality of agricultural products.

Production technology of biological fertilizer

Compared with common organic fertilizer, biological fertilizer production technology content is higher. In order to realize directional decomposition and deodorization, biological agents should be added in the decomposition process of organic materials. In addition, microorganisms with specific functions should be added to the product to improve the effect of the product.

In the production process, there are also differences between biological fertilizer and ordinary organic fertilizer. In chemical fertilizer production equipment, biological fertilizer production equipment is the same as ordinary organic fertilizer production equipment, including fertilizer granulator, mixer, crusher, drum plate machine and other equipment. The difference between the two is how to protect the functional bacteria in the production process and improve the survival rate of the strains, so as to maximize the fertilizer efficiency.

Extrusion VS Rotary Granulation

In the process of chemical fertilizer manufacturing, various powders, small pieces, aqueous solutions or melted raw materials are made into particles with necessary appearance and compressive strength. According to the chemical properties of raw materials, efforts should be made to reduce dust pollution, improve performance and improve production and processing effect.

According to the fertilizer manufacturing process in granulation, according to the different aggregation methods of the initial ultrafine particles, the processing technology of the granulator can be divided into extrusion granulation, rolling granulation, spray granulation, hot melt making and fluidized granulation. Pressure granulation and rolling granulation are two common methods of fertilizer production. What is the difference between the two fertilizer production methods?

The pressure granulation method limits the powder form in the closed internal space, releases the external force, and improves the compactness of the material. Pressure granulation can be divided into two types, one is compression molding granulation, in which raw materials are placed in a closed mold cavity and extruded into a cylindrical belt according to repeated movement. The other is double roller granulation, which is commonly used in double roller granulator. In the process of sand pressing, raw materials are crushed, granulated and screened. With the popularization of rollers, materials are formed.

Double roll extruder granulator

Rolling granulation is to infiltrate the binder into the fine powder on the solid disk to produce micronuclei. The rearranged particles are rolled many times and then become spherical particles of a given size. The equipment of roller granulator usually includes disc type fertilizer granulator and rotary drum granulator.

Granulator is an important part of fertilizer processing technology. In order to save costs, some enterprises usually only choose the appropriate granulation equipment for production. Therefore, granulator is not only used in industrial field, but also used in chemical industry and agriculture. According to the market application, granulators include fertilizer granulator, sawdust granulator, plastic granulator, pulverized coal granulator, etc. Understanding the different granulation methods in fertilizer production is helpful to purchase appropriate granulation equipment.

Disc Granulation Plant Installation

Disc granulator is the main pelletizing equipment in fertilizer manufacturing process. The disc granulator can be used to produce organic fertilizer, compound fertilizer and other material particles. So, how to install and maintain these fertilizer manufacturing equipment to extend their service life? Here's the fertilizer maker.

2. Commissioning: before leaving the factory, the pan type fertilizer granulator has been adjusted and passed the strict quality and technical inspection, and has been approved to leave the factory. However, due to on-site maintenance or operation, the equipment still needs to be adjusted.

3. Operators should pay attention to regularly check the components easy to wear in the composition and structure of granulator, and observe whether the wear degree is serious or serious. If it belongs to the latter, it should be replaced immediately to prevent accidents caused by continuous use.

4. During the operation of chemical fertilizer equipment, some newly installed tires are easy to loosen and need to be checked frequently. In addition, once it is found that the temperature of bearing oil rises too fast or the rotating gear has abnormal impact sound, the power shall be stopped immediately, and the causes shall be checked and solved.

Organic fertilizer factory business plan

Organic fertilizer factory has many advantages and conveniences, and has a good market prospect.

1. Rich organic resources

The main raw materials of organic fertilizer manufacturing process are animal manure and plant residues. Animal manure is rich in raw materials, which is the waste that the farm is eager to solve, and its price is low.

2. High quality organic fertilizer

Taking pig manure as an example, the final urine of pig can be combined with garbage to produce 2000-2500 kg of high-quality organic fertilizer, which contains 11% to 12% of organic matter, 0.45% of nitrogen, 0.19% of phosphorus pentoxide and oxidation. Potassium is 0.6%, which is enough for one year's fertilizer. Organic fertilizer is rich in nutrients such as nitrogen, phosphorus and potassium, and the content is more than 6%, and the content of organic matter is more than 35%, which is higher than the standard content.

At present, organic fertilizer market is in good condition. Our company provides a complete set of organic fertilizer production plan free of charge to help you set up the factory, and can send engineers to guide the installation.

Granular fertilizer production technology

Flat die extruder is an important machine for organic fertilizer production. It uses extrusion for granulation, which plays an important role in fertilizer manufacturing technology. In our usual production activities, the methods of fertilizer granulation are various. To help you better understand the process of extrusion granulation, the main methods of extrusion granulation are explained below.

The flat die extruder uses pressure to gather solid materials, and then extrudes the material through rollers, which are driven by eccentric casing or hydraulic system. When extruding the solid material, the air between the powder particles is removed first, and the particles are rearranged to eliminate the gap between the materials.

The extruding granulator shall prevent the powder material from being in the extrusion granulation equipment, and then use external force to compress the powder material tightly. Due to the different ways of using external forces, molecules are reassembled, resulting in cylindrical particles. In the chemical fertilizer manufacturing technology, the whole process of production and extrusion is mechanical operation, without manual operation. Compared with stirring granulation, the shape of material is mainly made by stirring method, which is round.

Flat die extruder granulator

Double roller granulator is also used for extrusion granulation. It is commonly used in fertilizer manufacturing processes, such as compound fertilizers. The thickness of the large plate produced by the roller granulator is 5-20 mm, and the surface density is 1.5-3 times of the feed. Large plates are peeled, crushed and screened to obtain the desired granular products. The pressure formed particles form a hot spot at the contact point and melt the material. When the temperature drops, the material is cooled to form a fixed bridge.

The above is a detailed introduction of extrusion granulation method, which can help us to know more about it, so as to produce qualified granules in fertilizer production. There are many granulation methods in fertilizer processing technology, extrusion granulation is a common method.

Ammonium sulfate fertilizer production

Roller extrusion NPK fertilizer production line is suitable for the production of ammonium sulfate fertilizer. The production line adopts extrusion granulation method, which is suitable for a variety of raw materials. It can also be used to produce urea calcium superphosphate (or magnesium calcium phosphate), ammonium chloride (or ammonium sulfate) - superphosphate, ammonium chloride ammonium phosphate and ammonium phosphate. 

NPK fertilizer production line can produce special compound fertilizer including pesticide and hormone according to the needs of users.

The application method of ammonium sulfate is as follows:

(1) As base fertilizer. When ammonium sulfate is used as basic fertilizer, it is necessary to apply deep covering soil to promote crop absorption.

(2) Top. This is the most suitable application method. The amount of ammonium sulfate removal is determined according to different soil types. For the soil with poor water and fertilizer retention, it must be applied in stages, and the amount of each application should not be too much; for the soil with good water and fertilizer retention, the amount of each application should be more appropriate. The content of soil moisture also has a great influence on fertilizer efficiency, especially in dry land. 

When ammonium sulfate is applied, we must pay attention to timely watering. On the coat of paddy field, drainage and drying should be carried out first, and at the same time, the combination of tillage and tillage should be paid attention to. In addition, the application of ammonium sulfate in different crops also has obvious difference, if the tree ditch, ring or hole application.

(3) It is more suitable for seed fertilizer. Because ammonium sulfate has no adverse effect on seed germination.

Fertilizer roller extruder of fertilizer roller extruder

The single production capacity of our roller extruders is usually 1-4 tons / hour. In the design of NPK fertilizer production line, according to the production capacity of granulators, multiple granulators can be combined to meet the production line. Compared with other fertilizer granulators, the advantage of extrusion granulation is that it saves energy consumption of product drying and eliminates three kinds of waste treatment. In addition, the scale of the factory is small and the investment is small. Basic fertilizers and organic matter with heat sensitivity can be included in the compound fertilizer formulation. It is beneficial to maintain the characteristics of ammonium sulfate fertilizer. More detais in compound fertilizer granulation, https://www.fertilizermachinesale.com/double-roller-granulator/

Fertilizer Production Technology

Fertilizer production equipment is an important tool for agricultural development. Chemical fertilizer manufacturing technology not only helps to improve the living environment, but also creates profits. Fertilizer manufacturing technology should be combined with the experience of granulation and the use requirements of different materials to produce organic fertilizer, compound fertilizer and compound fertilizer according to the requirements of different fertilizer granulation.

The granulation method of chemical fertilizer manufacturing technology includes fertilizer granulation production line and urea granulation equipment.

Spray granulation: the main raw material of the process is concentrated liquid produced by the fermentation industry. Organic waste liquid is concentrated by multi effect evaporation, then mixed with a certain amount of mineral fertilizer to form slurry, then sent to spray granulator, and dried by high temperature hot air to form granules.

The application of sand blasting agent is not as convenient as granulation production line, and has the following characteristics:

1. The production range of organic fertilizer is narrow, and the material selection is limited to slurry.

2. Large investment and high energy consumption.

3. Integrated spraying, drying and granulation, easy to operate.

4. The product has good spherical shape, good physical properties and high grade.

Technological process of fertilizer manufacturing

Common process of fertilizer manufacturing technology

1) Fermentation diverter

2) Forklift. The fermented organic fertilizer is transferred to the semi-finished product stacking area by forklift truck, and the fermented organic fertilizer thrown out by rotary table machine every day is treated.

3) Drum projector. Fermented organic fertilizer will be screened, and large and large pieces of fertilizer will be separated for further crushing and packaging.

4) Crusher. The large fragments and stones in the selected organic fertilizer are separated and crushed, which is very beautiful and can ensure the product quality.

5) Mixer

6) Organic fertilizer granulator. Granular materials.

7) Dryer, cooler. Dry and cool the particles.

8) Granular fertilizer packaging machine. Granular fertilizer granules are packaged directly and then sold.

Powdery fertilizer is not easy to use in agriculture, it is easy to produce dust and cause pollution and loss. Fertilizer manufacturing technology makes the material granulated and greatly improves the product quality.

Biological Fertilizers Types

Different types of biological fertilizers have different uses. The amount of pure biological fertilizer is less, generally 0.5-2 kg per mu, used for seed dressing, root or leaf spraying. For example, Soybean Rhizobium fertilizer can be inoculated by slurry method. Generally speaking, 30-75 kg / mu is used as seed fertilizer for mechanical sowing. Generally speaking, the amount of bio organic fertilizer is large, 50-80 kg / mu is used as basic fertilizer. When bio organic fertilizer was used as basic fertilizer in dry land, it was applied in autumn and spring in combination with the whole field. Paddy field is used as basic fertilizer and biological fertilizer is applied once before water.

Fermenter for bio-fertilizer production

Biological fertilizer production line can adopt different raw materials and processes to make special fertilizer suitable for different crops. In the batch processing stage of biological fertilizer production, NPK inorganic fertilizer and other nutrients needed by crops are added and granulated by chemical fertilizer granulator, which can be processed into bio organic inorganic compound fertilizer. Bio organic inorganic compound fertilizer combines the dual advantages of organic fertilizer and inorganic fertilizer, which ensures that crops can obtain nutrition in short term and fertilizer effect in long-term supply. The fertilizer granulator of the biological fertilizer production process makes the raw materials into granules, which is convenient for the storage and use of the products.

Application of biological fertilizer

1. The manufacturer of chemical fertilizer machine reminds you that the effect of applying bio organic fertilizer on the basis of conventional fertilization is the best, and biological fertilizer should be applied continuously. If the fruit trees need phosphorus and potassium, not only can not reduce phosphorus and potassium fertilizer, but also increase phosphorus and potassium fertilizer appropriately. In the application of P and K, some soil lacking P and K should be increased. The combination of biological fertilizer, organic fertilizer and inorganic fertilizer has the best promoting effect on crops.

2. It should be noted that due to the nature of biological fertilizer, it should not be mixed with ammonium bicarbonate, plant ash, potassium sulfate, ammonium sulfate, etc., otherwise, the fertilizer efficiency of bacterial fertilizer will be affected.

3. When biological fertilizer is used as basic fertilizer or top sheet, it should be covered with soil in time to avoid affecting fertilizer efficiency. Want to get to know bio-fertilizer production process, welcome to https://organicfertilizerplants.com/bio-organic-fertilizer-production/

Disc granulator technology design

The disc granulator is one of the indispensable equipment in the production of spherical fertilizer granules, which plays a very important role in the production. How to make the pan granulator play a more effective role in NPK fertilizer production line? Let's talk about how to improve the efficiency of fertilizer production.

1. The first is the selection of the disc granulator equipment. According to different production environment and production requirements, users can choose the material and shape of the disc granulator. We also have stainless steel granulator equipment to meet the different needs of users. According to different production requirements, the diameter of the selected disc is also different, 1000-3600mm, users can choose according to the parameters. If the NPK fertilizer production line has a large output, you can buy more than one NPK to improve the production efficiency.

2. Second, the composition and moisture of raw materials determine the granulation rate of granules in the pan fertilizer granulator, so as to ensure the composition of materials that can be rolled into balls. Due to the late drying, it is impossible to reduce the water required for granulation, which will seriously affect the granulation rate.

3. Adjust the tilt and rotation speed of the pan fertilizer granulator. Generally speaking, the tilt angle of the rotating table of the disc granulator can be adjusted. However, the original manufacturer has adjusted the reasonable angle of the pan granulator. When users adjust themselves, they should adjust moderately, not over adjust, to prevent equipment damage. Similarly, the rotation speed of the disc should be kept in a reasonable range. If the materials are different, you can adjust the rotation speed slightly.

Pan fertilizer granulator

4. Finally, the granulator equipment needs to be repaired in time. Due to the tilting operation of the disc granulator, the torque transmitted by the spindle is very large, so it is necessary to timely repair, remove the fault and add lubricating oil to ensure the continuous operation and production of the equipment.

Organic fertilizer from oil palm

Oil palm is an evergreen woody plant. It not only consumes a lot of nutrients, but also has the characteristics of nutritional needs. In addition to N, P, K and trace elements, the demand for cellulose is also higher. It is not enough to use chemical compound fertilizer to grow oil palm. 

Predatory use of soil will eventually lead to the deterioration of soil environment and the increase of plant diseases, which will eventually fail to produce. Special oil palm fertilizer can be processed by organic fertilizer production equipment to meet the growth needs of palm oil.

Compared with chemical fertilizer, the application of organic fertilizer in oil palm has incomparable advantages

1. Organic fertilizer has comprehensive nutrients, and long-term uniform release. Organic fertilizer is rich in nutrients needed for the growth of oil palm. Energy sources continue to supply oil palm growth. In addition to a large number of elements, it also contains medium and trace elements, which can promote the comprehensive development of oil palm.

2. Improve soil structure and enhance soil nutrients. Because the tropical soil is mostly red loess, the soil is barren, organic matter and nutrient content is low, organic fertilizer contains a lot of organic matter, which can improve soil physical properties, improve soil quality and fertilizer preservation, and prevent soil erosion.

3. Improve soil biological activity and promote the growth of oil palm. Organic fertilizer is the main energy and nutrient source of microorganisms. The application of organic fertilizer is conducive to the activity of soil microorganisms, which can produce a variety of amino acids and plant hormones, and promote the growth and development of palm oil.

Petroleum Paman fertilizer granules

Palm oil is also a good raw material for processing organic fertilizer. The waste compost can be processed into organic fertilizer after fermentation by windmill turntable. According to the growth needs of oil palm, appropriate NPK inorganic fertilizer, compost and mineral elements should be added, and special fertilizer should be produced by organic fertilizer granulator to meet the demand of oil palm. Learn more.

Fertilizer Grinder Role in Production Line

Crusher is necessary for chemical fertilizer production line of chemical fertilizer plant. It can crush raw materials and is suitable for further processing of fertilizer granulator.

Crusher in fertilizer production line

When using the crusher, the following points should be paid attention to:

1. After the equipment is installed and powered on, 3kg grease must be added to the bearing housing.

2. After 72 hours of operation, grease should be added to the bearing housing.

3. When closing, the machine can be shut down after the internal materials are discharged.

4. In case of sudden power failure, it is too late for the fertilizer production line to process the surplus materials. When there is residual material in the machine, you need to manually move the triangle belt to remove the material.

5. If there is too much debris discharge, please open the screws on both sides of the machine, and then observe whether the blade is worn into arc. If the wear is a circular arc, the pin can be pulled out and the bit will continue to be used. If the wear is very serious, replace the bit with a new one.

Granulator Maintenance Tips

With the development of agriculture and the improvement of technology, market demand began to diversify. Due to its high efficiency and good granulation effect, rotary drum granulator is also very concerned. Drum granulators is an important part of NPK fertilizer production line. Its service life is related to the manufacturer's production quality, and more depends on the maintenance work of users' daily use.

How to keep the rotary drum granulator in daily production

Rotary drum granulator

1. Keep the workplace clean. After each use, the residual material inside and outside the granulator shall be thoroughly removed and the exposed machine cleaned. It is better to cover the outdoor machine with protective cover to prevent the secondary invasion of dust.

2. The gears and worm gears of the granulator are lubricated with special grease. Add grease once at a time and frequently drop oil between sliding surfaces of hinge joint between supporting gearbox and bracket. The gearbox should be thoroughly cleaned and all protective lubricants should be replaced annually after use.

3. Pay attention to the operation of fertilizer granulator. In case of serious abnormal noise, drying sound and metal friction sound, please stop using immediately and check after troubleshooting.

4. If it fails to work, check whether the power supply voltage, power plug and socket, connecting plug and socket are normal, and check the internal fault of the controller.

Pan Granualtion Equipment Working Principle

In the process of compound fertilizer powder processing, there are many factors that affect the granulation rate of disc granulator, but the influence of each parameter is not isolated, but interrelated and included. In NPK chemical fertilizer production line, the relationship between parameters should be adjusted according to the actual situation, so as to achieve the best spherical yield.

Ball forming principle of Pan fertilizer granulator

The disc is mounted at a certain inclination. The material in the rotating disc rolls rapidly with the rotation of the main body of the disc. When it rises to the highest position, it falls vertically under the block of the scraper. 

In the process of rotating the disk, it is squeezed and rolled by the disk wall under the action of centrifugal force. As a result of these all-round mechanical extrusion, rolling, collision, powder materials gathered together, with the help of the surface tension of the liquid phase, the "mother ball" is formed. With the increase of "mother ball", the particles are gradually spheroidized into complete particles, and the strength increases gradually from small to large. 

The granulation process is completed until the particle size of the finished product overflows from the edge of the disc. The disc granulator has a good classification function, so that the powder material grows from the bottom of the disc to the earth, forming particles overflow to the outer disk. 

With the increase of the diameter of the outer disk, the linear velocity of the particles increases suddenly. Particles are rolled and rubbed to form spherical particles. Larger particles are prevented from spilling into the hopper by the discharge plate and then sent to the next process by the belt conveyor.

Pan fertilizer granulator

The chemical fertilizer is also produced in different proportions of different chemical fertilizers. Due to the influence of different fertilizer types, in order to achieve high ball rate, the parameters of fertilizer granulator should be adjusted according to the specific situation, so as to achieve the best granulation effect and improve the production capacity.
