Organic Composting Technology

Composting in the process of organic fertilizer production is a traditional biological method for the treatment of straw and livestock manure. Under certain conditions, it is necessary to ferment the degradable organic matter in livestock manure and straw through the action of microorganisms, and then decompose them to produce products with certain fertilizer efficiency. After continuous improvement and optimization, composting of organic fertilizer production has developed towards mechanization and commercialization, and has become one of the effective methods to treat livestock manure and straw.

Attention should be paid to the following aspects in composting fermentation during the production of organic fertilizer

(1) The moisture content of compost in the organic fertilizer production line should be 60% - 75% of the dry material, that is to say, if you hold the material tightly, there will be water droplets extrusion, indicating that the moisture content is moderate.

(2) Good ventilation should be maintained at the initial stage of composting. If necessary, aeration tower, ventilation ditch and trough composter can be set. At a later stage, the aeration tower can be removed and the ventilation ditch can be blocked. Compaction, slurry sealing and plastic cloth covering can be used to preserve nutrients and promote humus accumulation.

(3) The internal temperature of compost can be controlled between 50 ℃ and 60 ℃. When the temperature is higher than 65 ℃, the compost can be turned over or cooled by adding water to facilitate the preservation of nitrogen.

(4) The C / N ratio of compost material was 25 ∶ 1, which was favorable for microbial decomposition of organic matter. Urea can be properly added in the composting process of straw fertilizer.

(5) Control the appropriate pH value. In the composting process, 1-1.5 kg lime and other alkaline substances were added to 50 kg straw to adjust the pH value of compost to about 7.5.

Organic Fertilizer Production Technology for Beginners

What if some investors who plan to build organic fertilizer plants have money but no technology? This problem is not difficult to solve. There are several ways to obtain organic fertilizer production technology and how to understand fertilizer production projects.

1. Go to the chemical fertilizer plant to understand the overall success of organic fertilizer production. You may not be able to get the specific production formula, but at least do a preliminary understanding, imagine the basic steps of plant construction, and develop preliminary plans and ideas. The finished organic fertilizer does not need to be granulated, but needs a fertilizer granulator.

Production technology of constructing organic fertilizer plant

2. Gain some experience from organic fertilizer equipment manufacturers. Generally speaking, experienced organic fertilizer equipment manufacturers usually have business contacts with organic fertilizer processing plants, including equipment purchased in the initial stage and maintenance equipment in the later stage. The technical personnel of the organic fertilizer equipment manufacturer are familiar with the organic fertilizer production process. Otherwise, how to maintain the equipment. When purchasing organic fertilizer manufacturing machine, consult more.

3. Obtain production technology from organic fertilizer fermentation agent manufacturer. This is a relatively simple method because the organic fertilizer starters they sell are mainly used for organic fertilizer fermentation. Not only do they provide you with the right starter. It will also guide the corresponding fermentation technology, without which the products may not be sold.

In short, before the construction of the organic fertilizer plant, I personally experienced the production process of organic fertilizer, learned how to use the equipment to produce organic fertilizer by communicating with the organic fertilizer equipment manufacturer, and understood the organic fertilizer fermentation working point and related technology through communication with the organic fertilizer manufacturer.

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.

Double Roller Granulator Installation Guides

 Guide for installation and commissioning of organic fertilizer double roller granulator

1. Installation:

After arriving at the plant, the drum extrusion organic fertilizer granulator will be installed with granulator as the main machine. According to the number of units and the organic fertilizer manufacturing process flow chart, the elevation and horizontal position are found. There are corner holes in the frame, which can be installed on the concrete (the solid vibration is not large, and a very solid concrete foundation is not required).

Guide for installation and commissioning of organic fertilizer double roller granulator

2. Debugging:

Our double roller granulator has been debugged before delivery, but it still needs to be adjusted after trial.

(1) Adjust the press roll clearance

In the production process, it is sometimes necessary to increase data output or data biting angle. In this case, the distance between the two compression shafts can be increased and the clearance between the drive shaft roller and the drive shaft can be increased.

The steps are as follows: stop the roller granulator, remove the frame above the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness, prevent the roller collision between the two rollers, and maintain a minimum clearance of 0.3-1 mm. Go here for details.

(2) Ball and socket alignment adjustment

The ball and socket are formed by pits on the surface of the main roller, so there are problems of axial alignment and circumferential alignment.

Axial alignment has been adjusted during installation. Generally speaking, the possibility of adjustment is very small. When adjustment is required, tighten or loosen the seal rings on both sides of the passive bearing housing to push the displacement of the eccentric sleeve corresponding to the roller of the drive shaft.

Align the circumference. The steps of circumferential alignment are as follows: loosen the 6 connecting bolts of the drive gear and the adjusting sleeve, so that the adjusting sleeve and the driving gear are slightly separated. Since a spherical and socket adjustment is considered in the design and two adjusting bolts are provided, the deviation can be adjusted no matter the deviation is too large. As the ball sleeve of the double roller granulator is too small, the paperboard is placed between the two rollers during the adjustment process. After scrolling, you can see whether the adjustment has achieved the goal. After alignment, tighten the 8 connecting bolts.

NPK Granulation Tech

Granulation technology of NPK fertilizer production line with rotary drum granulator

Rotary drum granulator is the main granulating equipment of NPK fertilizer production line. It uses powder composition and agglomeration granulation method to make NPK compound fertilizer molding. The drum granulator developed by our factory adopts a new generation granulation technology, which improves the formation rate of compound fertilizer granules and the qualified rate of primary granulation.

NPK Fertilizer Granulation Plant

Rotary drum granulator

The rotary drum granulator can make NPK compound fertilizer into granules, which is easy to store and release, thus greatly prolonging the fertilizer utilization rate of organic fertilizer. The drum granulator is suitable for cold and hot granulation. It uses aggregate wet granulation, and adds a certain amount of water or steam to the cylinder, so that the extrusion force between the material particles can be condensed into a ball.

Granulation technology of NPK fertilizer production line

In order to improve the granulation performance of rotary drum granulator, we improved the drying process of NPK fertilizer production line after granulation. It can shorten the drying time of fertilizer production, minimize the damage of compound fertilizer particles in the drying process, and increase the numNPK Granulation Tech

For NPK fertilizer granulation, the quality of granulation particle size depends on the proportion and feedback granularity to a certain extent. Compound granulation usually needs batch quality, and the quality of returned materials is the key to control the production of rotary drum granulator. On the basis of ensuring nutrients, the quality of returned materials mainly depends on the size and distribution of returned materials. In order to ensure the quality of returned materials, we set up chain crusher in NPK fertilizer production line.

The chain crusher will re crush the unqualified returned materials, and the crushed powder can meet the granulation requirements of the rotary drum granulator.

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.

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.

Pan Granulation Technology

As a fertilizer granulator which has been used for a long time in chemical fertilizer plant, pan granulator has its unique advantages. In the production of fertilizer granulation, the following factors exist in the particle uniformity.

Structure of pan pan granulator

The disc granulator adopts the whole arc structure, which effectively improves the granulation rate. Combined with non power scraper equipment, it can reduce the accumulation of materials in the granulation process and maximize the use of raw materials. In order to facilitate the flexibility and flexibility of field use, the base is firmly thickened and weighted, without the need for additional anchor screws to fix, which also helps to prevent chassis deformation. The disc granulator is very suitable for field operation, reduces the tedious installation and layout procedures, saves time and improves the work efficiency.

In the granulation stage of NPK fertilizer production line, with the continuous addition of raw materials, under the action of centrifugal force, the manufactured particles fall into the lower belt conveyor through the edge of the plate.

Pan fertilizer granulator

Elements of Pan fertilizer granulator

When the plate granulator processes raw materials, many parameters affect each other. For example, the smaller the diameter of the pelletizing disk is, the lower the disk height is, the larger the inclination angle of the disk is, and the higher the rotation speed is; if the disk height is increased, the inclination angle and rotation speed are higher. The smaller the tilt, the lower the speed.

As a NPK compound fertilizer production equipment, another factor affecting the disc granulator is the tilt angle of the disc. The angle of inclination should not be less than 35 ° during granulation, otherwise the material will stick to the disc and rotate with the disc body. With the increase of inclination angle and rotation speed, the material can avoid accumulating in the lower part without falling and rolling up and down.  More info on pan granulation process, go here with the link.

However, the larger the inclination angle is, the faster the downward rolling speed is, and the smaller the overflow particles are. The most suitable slant point of the disk is related to the diameter of the disk, that is, the slope of the disk decreases with the increase of the disk diameter. 

This is because the end velocity of particles moving along the disk surface increases as the disk diameter increases. In order to avoid the impact and fracture of other particles when the particles are down, the tilt of the disk must be reduced.

Wet Granulation Line

The supporting equipment of fertilizer granulation production line includes: composter, crusher, mixer, fertilizer granulator, belt conveyor, dryer, cooler, drum screen machine, automatic packaging machine for finished products. Fertilizer production line can not be without granulator, but in the granulation equipment, plate wet granulator has become a classic, why?

Disc wet granulator equipment

There are five reasons why the pan granulator is widely used

1. The new structure of disc granulator reduces the weight and height. The layout of chemical fertilizer production process is flexible and convenient, which is suitable for the transformation of old plants.

2. The tilt angle of the large plate can be adjusted. The angle gasket is flexible and easy to adjust.

3. The granulator adopts unique non power combination scraper integration to reduce auxiliary power consumption.

4. The large board is composed of the board body and the board part to reduce the power of the main motor. In addition, the disc connector can be adjusted up and down along the disc body.

5. New design of disc granulator, edge cleaning and bottom cleaning by combination scraper without power, angle cleaning scraper winding angle, with unique disc body processing technology, good dredging effect, no large mud, material ball diameter of 90% in 3-5mm.

The advantages of selecting disc granulation production line are that the whole set of equipment is easy to operate, the adjustable range is large, and the finished product particles are round. This wet granulation line has been considered as the preferred configuration for fertilizer granulation!

NPK fertilizer production

How to avoid fertilizer clumps in NPK fertilizer production

Fertilizer blocking problems usually occur in the process of fertilizer processing, storage and transportation, and are caused by the absorption, dissolution, evaporation and recrystallization of fertilizer particles. In this process, a crystal bridge is formed, causing small particles to form large particles and clump.
So how to avoid the fertilizer clumps generated by NPK fertilization equipment?

1. Choose the right raw material.

Fertilizer production of raw materials, such as ammonium salts, phosphates, trace element salts, potassium salts, etc., mostly contain crystalline water, easy to absorb water, such as ammonium sulfate, phosphate, trace elements easy to reunite, insoluble in water. Urea is prone to extract water and clumps with trace element salts.

Choose raw materials that are not easy to clump and produce fertilizer that does not clump. For example, fertilizers with humic acid as the main raw material and amino acids as the main raw materials are not easy to clump. Also, try to keep the material dry when selecting it.

2. When producing NPK fertilizer, the water content and packaging temperature of the fertilizer should be reduced and the appropriate production time should be selected.

Fertilizer production is generally non-closed. During the production process, the greater the air humidity, the easier the fertilizer is to absorb moisture clumps. Fertilizer production avoids the rainy season and concentrates on fertilizer production on dry days. In the fertilizer production process, the raw material is heated by dryer, so that the water content of fertilizer is controlled at 0.6%, prolonging the cooling time of fertilizer, reducing the packing temperature, making the fertilizer not easy to clump.

3. Add anti-clumping agent to reduce the physical chemical reaction between NPK fertilizer particles.

The higher the room temperature, the easier it is to dissolve. In general, raw materials dissolve in their own crystalline water and cause clumps. Adding talcum powder, humic acid and other non-clumping powders can also be added some surfactants to prevent clumps.

4. Reduce the height of the fertilizer stacking and storage pressure.
The greater the external pressure of fertilizer, the easier it is for the crystal to clump in contact with the crystal, and the smaller the external pressure, the more difficult it is to clump.

5. The NPK fertilizer can be screened with a screening machine to further improve the uniformity of fertilizer particles.
NPK fertilizer particle size is not uniform, particle spacing is small, contact area is large, easy to reunite. If the pressure strength of fertilizer particles is low, deformation and breakage are easily occurred during packaging, transportation and storage, increasing the contact area between the particles, which can also lead to fertilizer clumps.

If the fertilizer plant uses NPK fertilizer production line to produce a large amount of fertilizer, can be used for two screening machines to obtain suitable fertilizer particles.

6. Production of NPK fertilizer particles.

Because of the small contact area between circular particles, it is not easy to crystallize the clumps. Therefore, the granulation of nitrogen and phosphorus potassium fertilizer is beneficial to the storage, transportation and fertilization of fertilizer.

When using roller granulators to produce NPK compound fertilizer particles, the dryer is not used, but the raw materials for the production of fertilizer must have good adhesion.

When producing NPK compounding particles with a disc granulator (or drum granulator), it must be dried and cooled.

Choose Compost Machines Based on Technology

The compost turner machine's primary job is for making organic fertilizer. This procedure happens throughout the fermentation and composting of organic wastes like garbage filters, sludge from industries, mud straw, as well as animal manure, amongst other things. The procedure is inexpensive and in addition ensures zero environmental degradation. The most frequent means of composting is truly the natural way of fermenting by permitting these waste rot away. However, the compost turner machine is very efficient since it adopts these types of technological advancements.

Windrow Composting.


Also referred to as aerated or turned composting. This technology of composting is quite efficient for larger volumes of substances. Almost all of this waste will come from communities hence the extensive collection done by the regional government in a central place. Businesses with good-end food processing activities like restaurants also play a substantial role. This process works by forming organic waste into rows from the name windrows. Later, there exists aeration that can take place at intervals. The ideal windrow height is between four to eight feet, based on the use. Using the size, there exists a guarantee which it will achieve including the flow of oxygen, and enough heat will pass to aid retain the temperatures. Compost Turner taht use windrow composting tech, welcome to https://compostturnermachine.com/compost-windrow-turner/

Vermicomposting

You may always find worms in waste bins, which is their supply of food. However, this feeding helps a whole lot in the creating of compost from your available waste. The waste is split up into high-quality compost through the name castings. Using this technology, worms are actually an excellent business when you quickly purchase them from the market. Therefore, it is very important place this waste in quantities dependant upon the intake of the worms. One pound of worms can eat up to half-pound of organic material. This method takes almost four months to complete. The castings are beneficial since they are available as potting soil. Also, there is certainly another by-product of this technology called worm tea,  another type of fertilizer. Here are detailed info and machines related to vermicomposting technology https://manurefertilizermachine.com/industrial-vermicomposting-equipment/

In-Vessel Composting.


This technology is sufficient as it helps with the composting of organic materials by using minimal space as compared to the windrow method. Also, there is a accommodation of an array of materials from animal manure, food scraps, and biosolids, among other elements. The substances enter into a silo or any other equipment equivalent to a drum. This vacuum ensures there are actually stable airflow and temperature. Mixing from the materials then starts for several minutes to boost aeration. The method takes to a couple of weeks just before the compost is prepared.  You use various sizes of drums based on the need of use. More info on in-vessel composting, welcome to https://compostmachinery.com/in-vessel-composting/

Onsite Composting.

Onsite composting can be a composting method efficient for places with minimal levels of organic materials. Organizations producing yard trimmings and average food waste can adapt this method for producing their fertilizers. However, animal merchandise is not recommendable for this sort of composting.

Nevertheless, you can find five essential components of these composting technologies which require strict controlling to ensure the processes are successful. Included in this are sizes of particles, temperature, the flow of oxygen, moisture content, and nutrient balance. Adhering these conditions will yield composts of the finest quality.
