The roll extrusion granulator is an important granulator in Manure and compound fertilizer production lines. It does not need to add any wetting agent. The roll extrusion granulator is simple in process and easy to operate. Most compound fertilizer manufacturers prefer the roll extrusion granulator. The installation and debugging of the roller extrusion granulator equipment are also very simple.

Use characteristics of Organic fertilizer equipment roll extrusion granulator:

1： After the pressure wheel of Organic fertilizer granulator is increased, the bearing is increased, and the pressure bearing capacity is enhanced.

2： After the pressure wheel is increased, the temperature generated by squeezing friction is not easily transmitted to the bearing chamber, ensuring that the lubricating grease of the bearing is not easy to overflow when working at low temperatures.

3： After the pressure wheel is increased, the pressure wheel can be pressed for 2-3 times, extending the service life of the Manure granulator, reducing the production cost, and increasing the profit margin of the investment project.

4： This model adopts multiple evenly distributed compression wheels, ensuring smooth operation and increasing the compression area, thereby improving production efficiency.

5： This model has a variety of compression molding options, with round bars and particles that can be made by simply changing the mold, suitable for compression molding of different materials.

The Organic fertilizer granulator is mainly suitable for coarse fiber granulation, such as various crop straws such as wood chips, rice husks, cotton stalks, cotton seed hulls, weeds, domestic garbage, factory waste, materials with low adhesion rate and difficult to form, and also suitable for low-temperature granulation of biological bacterial fertilizer, Manure, compound fertilizer, etc.

The roller extrusion granulator has the characteristics of low investment, high efficiency, superior performance, convenient use, and green environmental protection. By using the roller dry production process to complete the granulation of compound fertilizer, the material is directly compressed into particles at room temperature. This equipment is a multi element compound fertilizer produced using ammonium carbonate, urea, ammonium chloride, ammonium phosphate, and other basic materials. It has high strength and good slow-release performance, achieving long-term, controlled release, and slow-release effects, and can improve fertilizer efficiency by more than 20%. At the same time, the equipment also solves the problem of insufficient particle strength of Manure produced by domestic rotary drum and disc granulation equipment. In addition, due to the adoption of a new technology of dry powder roller pressing granulation in the equipment, there is no loss of materials and physical properties in production.

Cow dung and accessories are mixed together to form a moisture content of 50-60%, which is kneaded by hand and printed with water between fingers but not discharged. When the stacking height is 0.8m-1.5m and the ambient temperature is below 15 ℃, cover with film or straw curtain. When the internal temperature rises to 25 ℃, the covering is uncovered. Generally, in the fermentation of 2 to 3 days, the organic fertilizer machine turns over the material and then ferments. The purpose of doing this is to make it fully ferment and kill pathogens and eggs. The purpose of turning once is to let a large amount of air enter into it and make it heat again and ferment again. In general, the fermentation is complete in seven days. Next, we can make granular organic fertilizer.

1. In the period of cow dung fermentation, the material was crushed by a crusher, so that the particle size requirements after crushing could meet the requirements of later organic fertilizer granulator production.
2. Use forklift truck to put manure organic fertilizer into the mixing mixer. Before mixing and mixing, according to the formula, add n, P, K and other trace elements into the mixing mixer to start mixing.
3. The mixed materials are transported to the organic fertilizer granulator, and the granulated materials are sent to the cooler after drying. The materials are sieved at room temperature. The particles that meet the requirements enter the coating machine and are packaged after coating. The particles that do not meet the requirements return to the granulation system and continue granulation.
4. The final qualified granules are packed automatically.
Note: the production of cow manure organic fertilizer can be made into powder or granular form. The organic fertilizer manufacturers need to choose the production mode according to their actual situation, and expand the investment scale when the opportunity is ripe in the future.

The dry powder double roller extrusion granulator is mainly used to press the powder materials which are difficult to form. It is characterized by large forming pressure, adjustable rotation of the main machine, and equipped with screw feeding device.
The main machine of the dry powder double roller extrusion granulator is powered by the electromagnetic speed regulating motor, which is transmitted to the driving shaft through the belt pulley, the cylindrical gear reducer and the bar pin coupling. The driving shaft and the passive shaft of the organic fertilizer granulator are ensured to run synchronously through the open gear. A hydraulic device is arranged behind the passive bearing seat.

The screw feeding device of the dry powder double roller extrusion granulator is driven by the electromagnetic speed regulating motor, and is rotated by the belt pulley and worm reducer to force the pressed material into the main feeding port. Because of the constant torque characteristic of the electromagnetic speed regulating motor, when the pressing amount of the screw feeder is equal to that of the main machine, the constant feeding pressure can be maintained to stabilize the pellet quality. In the fertilizer production line, if the feeding quantity is too large, the electric overload of the feeding device will occur; if the feeding quantity is too small, it will not form a ball. Therefore, skilled operation technology is an important condition to ensure the normal operation of the pressure ball.
The hydraulic protection device is driven by the hydraulic pump into the hydraulic cylinder to make the piston produce axial displacement. The front connecting head of the piston rod is on the bearing seat to meet the production pressure requirements. When there is too much feeding between the two rollers or metal block, the piston rod of the hydraulic cylinder is pressed and overloaded, the hydraulic pump will stop, the accumulator will buffer the pressure change, the overflow valve will open the oil return, the piston rod displacement will increase the gap between the rollers, so that the hard objects pass through the rollers, the system pressure will be restored to normal, which can protect the rollers from damage. This organic fertilizer granulator can adjust the pressure according to the requirement of the pressure ball density, and the production is flexible.

Sheep manure organic fertilizer production line is mainly sheep manure, straw, branches, straw production and processing of organic fertilizer. Sheep manure organic fertilizer is a new type of high quality organic fertilizer after special treatment of sheep’s incompletely digested organic matter. It is suitable for geological improvement of alkaline soil and barren land, and has a good effect on increasing crop yield.

Technological process of sheep manure organic fertilizer production line
1. When sheep dung is mixed with appropriate amount of straw powder, the amount of mixing depends on the moisture content of sheep manure. Generally, 45% water content is required for fermentation, that is, the hand is squeezed into a ball, and water can be seen between fingers, but no water is dropped. Once the hand is released, it will disperse. Then, corn flour and bacteria were added. The function of corn flour was to increase sugar content for bacteria fermentation, so that multi-dimensional complex enzyme bacteria quickly took the absolute advantage.
2. Add the mixed material into the mixer for mixing. The mixing must be even and transparent without leaving raw blocks.
3. The mixed ingredients are piled into strips with a width of 1.5m-2m and a height of 0.8m-1m, which are tossed by a compost windrow turner every two days.
4. The compost was heated in 2 days, odorless in 4 days, loose in 7 days, fragrant in 9 days, and composted in 10 days (that is, the temperature on the second day of composting could reach 60 ℃ – 80 ℃, killing E.coli, insect eggs and other diseases and insect pests; on the fourth day, the odor of sheep manure was eliminated; on the seventh day, the compost became loose and dry, covered with white hyphae; on the ninth day, it gave out a flavor of koji; on the tenth day, the compost was fermented and matured).
5. After a little air drying, it can be crushed by a semi wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready for packaging and storage.

Generally, organic compost is fermented for 15-20 days, and such products can only reach the harmless standard. The fermentation process of high quality organic compost usually takes 45-60 days. This is because in the early heating and high temperature stage of composting, plant pathogenic bacteria, insect eggs, weed seeds and other harmful microorganisms will be killed, but the main role of microorganisms in this process is metabolism and reproduction, and only a small amount of metabolites are produced, which are not unstable and easy to be absorbed by plants.
In the later stage of cooling, microorganisms decompose the organic matter and produce a large number of metabolites that are conducive to plant growth and absorption, which takes 45-60 days. Through this process, composting can achieve three goals: harmless; humification; and a large number of microbial metabolites, such as antibiotics, proteins and so on.
Organic fertilizer machine manufacturers tell you that fermentation methods are divided into high temperature compost and ordinary compost according to different raw materials. High temperature compost takes the plant material with high fiber content as the main raw material, and generates a lot of heat through composting fermentation under the condition of aeration. The temperature of compost is very high (50-60 ℃). Therefore, it matures quickly, composts quickly and has high nutritional content.
In the process of high temperature fermentation, pathogens, eggs and weeds can be killed. Common compost is usually mixed with more soil, with low fermentation temperature, slow decomposition process and long composting time. During composting, the chemical composition of nutrient differentiation changed, the ratio of carbon to nitrogen decreased, the mineral nutrients directly absorbed by plants increased, and humus formed.

The horizontal organic fertilizer fermentation tank has the following advantages:
1. High temperature aerobic fermentation, utilizing high-temperature microbial technology, has low energy consumption and operating costs;
2. The equipment occupies a small area and has a high degree of automation. One person can control it to complete the fermentation process;
3. By using biological deodorization equipment to achieve gas emission standards without generating secondary pollution;
4. The main body of the equipment is made of stainless steel special material, which reduces corrosion and has a long service life;
5. The main insulation design and auxiliary heating ensure the normal operation of equipment in low-temperature environments;
6. The treated domestic sludge, kitchen waste and livestock manure are used for processing organic fertilizer to realize resource utilization.
