Drum granulator application methods

As a fertilizer production machinery manufacturer, users often consult the use of the machine after purchasing equipment from our factory. They have some confusion in operation, especially large equipment such as drum granulator.

Here are six precautions for the operation of drum granulator.

(1) Before starting the power supply of the drum granulator, check the specified voltage and current marked on the motor to confirm whether the input voltage is correct and whether the overload relay is configured.

(2) The raw material does not fully enter the granulator. Air transportation is strictly prohibited to avoid damage to the equipment.

(3) The foundation of the drum granulator must be firm, and it is best to work in a vibration free working environment.

(4) Confirm whether the anchor bolts and screws of the rotary granulator are firmly installed.

(5) In case of abnormal phenomena such as startup, temperature rise and shaking, the equipment shall be checked immediately.

(6) Check whether the motor temperature is normal. When the load increases to normal load, check whether the current exceeds the rated current. In case of overload, high horsepower is more appropriate.

Pig Manure into Granular Compost

Pig manure organic fertilizer granulator: whether you like pork or not, 700 million pigs are there. The problem is that the value of pig manure brought by these 700 million pigs exceeds 100 million.

Pig manure is very "fat". Today, no one will question the necessity of environmental protection in pig breeding. How to do it has become a problem that the industry really needs to think about. The same thing may look completely different from different angles. 

In some people's eyes, these hundreds of millions of tons of manure can be a source of pollution, but in some people's eyes, it can't be a source of wealth? Turn pig manure into organic fertilizer and garbage into resources. Endless troubles have suddenly become endless benefits. All problems have been solved at once?

Reality will never be as full as ideal. Whether it is a pig farm or an organic fertilizer plant, it seems that there is no real way to combine the two. The production of organic fertilizer is a completely unfamiliar technology for pig farms, which is difficult to accept huge investment. For organic fertilizer plants, the use of pig manure raw materials is also full of unknowns. The fertilizer industry even spoke frankly about the various residues of heavy metals and antibiotics.

Who can build a bridge between the two first? We habitually think of the government. The government has done a lot of work, from regulation to subsidies. But everyone knows that the market is the greatest force. We are glad to see that leading enterprises such as Wenshi, muyuan and Dongrui have made many successful attempts.

Only when everyone in the market starts to benefit from it can the 100 billion market in the pig manure organic fertilizer theory be really activated, and then the pig manure will naturally become a fertilizer difference.

Q: how does pig manure mature?

A: pig manure has fine texture, low cellulose content and high nutrients. It is a good organic fertilizer. However, due to its high water content, slow maturity and less fermentation heat release, it belongs to cold fertilizer.

Its fermentation is slower than sheep manure and horse manure. Fermentation requires a certain temperature and humidity. The fermentation temperature of pig manure should reach 60 ℃ - 70 ℃, and the water content should reach about 60%. (the judgment method of 60% water content is to knead pig dung into a ball by hand and loosen it when it is loose.) if the temperature is not enough, cover it with film or mix some horse dung well. 

When the water content is high, the feces can be opened to evaporate the water. When it is not enough, add water. In addition, adding some nitrogen fertilizer can speed up the fermentation.

The standard for good fermentation of pig manure is: the color is yellow green, there are white mycelium like substances, the smell is not strong, slightly alcoholic. The water content of pig manure is 81.5%, organic matter is 15.0%, nitrogen is 0.60%, phosphorus is 0.40%, potassium is 0.44%. High nutrient content, balanced, soft, large and long fertilizer effect, it is "warm fertilizer".

 Pig manure has fine texture and complex components, including protein, fat, organic acids, cellulose, hemicellulose, inorganic salts, etc. Pig manure contains more nitrogen and a smaller carbon nitrogen ratio (14:1). Generally, it is easy to be decomposed by microorganisms and release nutrients that can be absorbed and utilized by crops. After decomposition, it can be applied to cold soil, sandy soil and clay soil to improve the soil.

Pan Granulation Technology

Organic fertilizer granulator is mainly used for coarse fiber granulation, such as: sawdust, rice husk, cotton stalk, cottonseed hull, weeds and other crop straw, domestic waste, factory waste and low adhesion rate, difficult to make material granulation. It can also be used for low temperature granulation of biological bacteria fertilizer, organic fertilizer and compound fertilizer.

The technology of disc granulator is introduced

1) The treated pig manure is directly transported to the raw material bin (or raw material mixer).

2) The pig manure is transported into the disc homogenizer and evenly added into the rotating disc of the disc granulator. Sprinkle the liquid component or appropriate amount of water through the liquid component distributor of the disc granulator. On the material in the disk, the amount of liquid phase needed to form the ball is satisfied; The rotating disk and the edge of the disk produce friction and centrifugal action on the material, which makes the material move in a circle, and the powder particles rub and knead each other. Extrude and gradually gather into clusters; Due to the different mass of particles, the gravity and centrifugal action are also different. When gravity and centrifugal force increase enough to overcome the friction between particles, they are thrown out of the disk. The smaller particles remain in the disk and continue to gather fine particles.

3) It is sent to the organic fertilizer dryer for heat exchange with the heat in the hot blast stove.

4) The fine particles are directly returned to the disc homogenizer, and continue to participate in the adhesion of particles to the ball as the core.

5) It is sent to the organic fertilizer cooler, and then the fertilizer is cooled with natural cooling air or strong cooling air.

6) The large particles are transported to the finished product screening machine, then crushed by the crusher, and then returned to the disc homogenizer to continue to participate in the formation of the ball.

7) The qualified products after screening are transported to the coating machine for coating treatment.

8) Transport to automatic packing scale for weighing, packing and storage.

9) After cyclone, labyrinth and wet scrubbing, dry, cool and workshop dust are discharged.

The production of organic fertilizer by disc granulation has the following advantages

The operation is intuitive, and the operation of the equipment can be mastered at any time. If any abnormality is found, it can be adjusted in time.

The particle size is determined by the tilt angle and rotation speed of the disk, and the tilt speed and rotation speed of the disk can be adjusted. Therefore, the disc granulation process has a wide range of particle size control, strong adaptability and high pelletizing rate, up to 70% - 90%.

The disc pelletizing process of organic fertilizer has the advantages of short production process, simple structure, less investment and simple operation, which is more suitable for small and medium-sized enterprises.

Bio Fertilizer Granulation Process

Bio organic fertilizer granulator basis

Bio organic fertilizer granulator is also a new type of organic fertilizer granulator, which has been widely used in the world. some time? It needs to be discussed.

Future development direction

Future development direction of bio organic fertilizer granulator: with the continuous development of bio organic fertilizer granulator, it has begun to play a role in agricultural production, and has produced certain economic benefits.

Transformation from single strain to compound strain

Transformation from single strain to compound strain: in this transformation process, one method is to pursue the application of multi-functional combined bacterial biological fertilizer, so as to further improve one or more characteristics of the strain from the original level. Avoid the interaction of complex or joint flora, and play mutual reciprocity and synergy. The second is to extend the survival time of microorganisms in the soil, and constantly extend the validity period of fertilizer. Therefore, the substances that can decompose carbonaceous compounds can be added to biological fertilizer to prolong the survival time of microorganisms in soil.

Simple biological preparation

It changes from simple biological preparation to compound biological fertilizer: from simple microbial preparation to biological microbial preparation, nutrient elements, organic fertilizer, etc. This transformation can realize the combination of biological fertilizer and medicine, and enhance the multi-function of fertilizer. In addition, the fertilizer granulator has also been transformed, and on the basis of the new organic fertilizer granulator, the fertilizer granulator is designed. The two in one organic fertilizer granulator can also be used to produce organic fertilizer granulator. This is a new improvement of pelletizer for bio organic fertilizer production.

With the continuous development of fertilizer manufacturing technology, new fertilizer granulators are also designed to produce high-quality fertilizer granulators. Therefore, both bio organic fertilizer granulators and compound fertilizer granulators are constantly developing. More details in bio fertilizer granulator, go here.

Biofertilizer Granulator Selection Tips

Biological fertilizer production is a new design of fertilizer manufacturing process. Compared with organic fertilizer manufacturing process, the production method is easy to be adopted. But how to choose fertilizer granulator technology to make biological fertilizer granulator is a factor problem.

Biological fertilizer granulator is also a kind of organic fertilizer granulator. The fertilizer granulator used in biological fertilizer production line is the same as that used in organic fertilizer production. The production technology of biological fertilizer granulator can be divided into various types according to different types of fertilizer granulators.

In terms of press, there are two types of commonly used technology of biological fertilizer granulator, namely disc granulator and roller granulator, which mainly depends on fertilizer granulator. Due to different granulation methods, the requirements of raw materials are different, and the production process of bio organic fertilizer is also different.

Pan Granulation Process: Pan mixing granulation process is relatively simple. After the raw material is dried, a certain amount of water is removed (after drying, the raw material is disinfected), crushed, and then a certain amount of acid and alkali is added. After adjusting the carrier, it is evenly mixed with the inorganic fertilizer part and sent to the disc granulator. In the process of granulation, a certain amount of microbial agent is sprayed, and the granulation product is dried at low temperature, and the finished product can be obtained after slicing.

After mixing and granulation: the raw material is dried to less than 10%, then crushed by fertilizer crusher, and mixed with acid-base regulator, inorganic fertilizer and microorganism, and then sent to roller granulator as fertilizer granulator. A fertilizer screening machine is used to separate the high-quality fertilizer granulator from the high-quality fertilizer granulator.

Quality Granular Fertilizer Production

 Granular fertilizer is favored by customers. Now there are more and more granulator manufacturers using chemical fertilizer in the market. Some new fertilizer manufacturers do not know the equipment well in the fertilizer production line. It is inevitable that there is no need to operate such a group of equipment, which leads to the uneven processing of fertilizer granules and the production of fertilizer particles.

 SX heavy industry has uneven fertilizer granules for the convenience of customers' use and processing Production problems and solutions of granulator for chemical fertilizer.

Matters needing attention in chemical fertilizer production:

1. The granulation process of fertilizer granulator is the fourth process in the chemical fertilizer production line, and the impact process before the granulation process has obvious impact on the granulation process, because the fineness and complete crushing will directly affect the granulation molding.

2. Granulating fertilizer source of drum granulator is used for processing and production, and the requirements for particles are different, ranging from 3 mm in diameter, 4 mm in diameter to 1 cm in diameter. Therefore, the production and processing of particles with different diameters are different from the requirements of grinding fineness. Generally speaking, the smaller the particle diameter is, the higher the requirement for grinding fineness is, the thinner the crushing is, and the better the uniform particles are formed.

3. If not thoroughly crushed, there will be large particles and small particles of raw materials. The processing of grain materials is not uniform, and the fineness of granular materials is not up to standard, which will also affect the formation of particles. Therefore, the crushing effect of the production line in the process of fertilizer production is very large. If it is found that the fertilizer granulation equipment is handling uneven particles, it is OK To start the disease from the comminution stage.

Large number of fertilizer granulator, with the characteristics of wide and heavy granulator, welcome to investigate!

Disc Granulator Structural Design

Pan Granulation Rate

Disc granulator is a new type of inclined plate pelletizing equipment, the granulation rate is more than 95%. The granulator of disc granulator has three discharge ports, which is convenient for intermittent production and greatly improves the labor efficiency. The production capacity can reach 24t / h. The reducer and motor are driven by flexible belt to make the starting stable and reduce the impact force. The bottom of the pelletizing pan is reinforced with a number of radiating steel plates, which are durable and non deformable. The thickened base design eliminates the need for anchor bolts. The main gear of granulator is quenched by high frequency, and its service life is doubled.

Performance 

Disc granulator has the advantages of uniform granulation, stable operation, high sphericity, high roundness, intuitive operation and convenient maintenance.

How does it work?

The raw powder is evenly wetted by the atomized water in the material mixer to form a spherical core with very uniform particle size, and then sent to the spherical disc for spherical formation. The moisture content of the ball should be controlled at 12-14%. Most of the water should be added to the twin shaft mixer. Only a small amount of make-up water is added to the ball plate, and the amount of water added is controlled at about 0 to 3%.

Finished products by pan granulation

The dry powder is directly added to the spherical plate and sprayed with appropriate amount of water. The core of raw material enters into the ball disc and is affected by centrifugal force, friction force and gravity, and moves along the parabola. Due to the adhesiveness and plasticity of materials, the cores adhere to each other and grow gradually in the process of movement. When the tilt angle, the height of the disc edge, the rotation speed and the humidity of the disc remain unchanged, the balls with different particle sizes will roll down from the edge of the disc at different exit angles due to different gravity. In the continuous rolling process, the ball constantly discharges water from the ball surface. Due to the cohesiveness of the material and the natural volatility of the liquid film on the surface, the ball has a certain strength, and then the swash plate body rotates. Both sides of the disc are discharged out of the carton. Detailed info, go here.

Granulation Process

Granulation Process

Any substance that can be coated on the soil or sprayed on the ground part of crops can directly or indirectly provide nutrients for crops, increase crop yield, improve product quality or improve soil properties, and fertilize soil, which is called fertilizer.

How to make organic fertilizer granules?

Organic fertilizer is the main component of fertilizer, which is also known as farmyard manure. It has a long history in agricultural development and plays an important role in the agricultural process. China is a large agricultural country. We attach great importance to the use of organic fertilizer. The most important planting is the quality of solid, and the organic matter in the solid is the foundation of soil fertility. Therefore, one of the most important things to use organic fertilizer is to increase the amount of organic matter in the soil. Organic fertilizers have important effects on soil structure, nutrients, energy, enzyme, moisture, gasification and microbial activity.

How does the granulator work in the agricultural production?

In agricultural activities, farmers often choose to use granular fertilizer. Easy to use and store. Our factory produces some granulators for making fertilizer granules. Now, let's introduce our new type of organic fertilizer granulator and pan granulator to you.

New developed technologies

First of all, the new type of organic fertilizer granulator is generally used for granulation of organic materials, such as agricultural waste, livestock manure, domestic waste, etc. the moisture content can be as high as 30-40%, the granulation rate is high, and there is still much organic matter. The raw materials can be directly granulated, and there is no need to dry after crushing.

Secondly, the pan granulator, which is also commonly used in the production of organic fertilizer. Simple structure, capacity from low to high, simple operation, final round particles, beautiful, granulation rate as high as 90%. So it's like a customer, also called pan granulator.

Drum Granulation Details

 How to promote the drum granulator working performance?

A certain amount of water or steam is added to the drum granulator fertilizer equipment to form a suitable solid-liquid ratio. Solid liquid materials are rolled and coated under the action of equipment to form particles of certain size.

Details of organic fertilizer production by drum granulator

1. The fertilizer granulator shall be equipped with two mixing powder boxes for granulation, so that the granulator does not need to stop when changing the formula.

2. A speed iron removal device must be placed before the organic fertilizer raw materials enter the roller granulator to protect the granulator from other impurities in the raw materials.

3. The organic compound fertilizer drum granulator should be placed on the cooler and the crusher should be placed under the cooler.

4. In order to make the organic fertilizer particles fall to the bottom of the box from a high place without damaging the bottom of the box, a vertical spiral slide should be installed in the box to slow down the impact force.

5. The finished product of granular organic fertilizer should be packed in the finished product warehouse. Pay attention to the fresh-keeping environment to avoid affecting the effect of organic fertilizer.

The above are some details that the granulator needs to pay attention to in the process of fertilization, which not only saves a small amount of power input, but also realizes the improvement of task efficiency, which is convenient and effective, and the effect is satisfactory. It has the characteristics of high strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life and convenient operation and maintenance. Go here for more deails in drum granulation equipment.

Organic Fertilizer Granulation Process

Urban pollutants and wastes are increasing. The production line of organic fertilizer recycles solid waste resources, which makes manure and agricultural straw into organic fertilizer. Manure is mainly produced by composting and granulation. Composting is the harmless treatment of raw materials by fermentation turning equipment. Granulation is the transformation of organic fertilizer into granular products, which is the key to the quality of organic fertilizer products.

Granulation requires a complete organic fertilizer production line equipment, with granulator as the core, including grinding, batch processing, mixing, drying, screening, cooling and other processes. Organic manure granulator is the core equipment in fertiliaer granulation. The processing method is: how to produce organic fertilizer with fertilizer equipment.

Function of organic manure granulator

Organic manure granulator can reuse a lot of useless solid waste to avoid occupying too much space and prevent bacteria in manure from happening for a long time. Using organic manure granulator to produce organic fertilizer can reduce the use of chemical fertilizer and pesticide, reduce pollution and promote ecological harmony. Organic waste contains a lot of pathogens and insect eggs. If not treated in time, pathogens can be transmitted. Organic fertilizer is a kind of slow effect fertilizer. After a large number of animal and plant residues, excrement and biological waste are completely decomposed, the domestic waste can be returned to the land in another form.

Solid waste from organic fertilizer production

Therefore, solid pollutants can be converted into organic fertilizer through the production machine of organic manure particles. Rational use of organic fertilizer can not only reduce environmental pollution, but also reduce chemical fertilizer input and alleviate the increasingly serious energy crisis. Organic manure granule manufacturing machine promotes agricultural product safety, green production and ecological environment protection from the source.

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.

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.
