Today, I’d like to talk with you about one of the most promising equipment in organic fertilizer machine — organic fertilizer granulator. Through the introduction below, I hope to help you better understand the organic fertilizer granulator.
To say the leader of the organic fertilizer production line equipment, the organic fertilizer granulator should be the first. The organic fertilizer granulator is the latest scientific and technological product developed by our company with many years of organic fertilizer processing equipment design and production experience. The organic fertilizer granulator is used to granulate all kinds of organic matters after fermentation, breaking through the conventional organic matter granulation process. Before granulation, the raw materials need not be dried and crushed, and the spherical particles can be processed by directly batching, which can save a lot of energy.

The feature of the fertilizer production machine is that the particles produced are spherical. The content of organic matter can be as high as 100% to realize the granulation of pure organic matter. Because organic particles can grow up and inlay with each other under certain action, there is no need to add binder during granulation. The particles are solid and can be screened after granulation, reducing the energy consumption of drying. After fermentation, the organic matter does not need to be dried, and the moisture content of raw materials can be less than 15%.
The influence of organic fertilizer granulator in organic fertilizer machine is very huge. The most important thing is that it is favored by the majority of manufacturers and brings more efficient fertilizer for the people.
Configuration of small pig manure organic fertilizer equipment: the configuration of small pig manure organic fertilizer equipment can complete production only by pulverizer, mixer, granulator, screening machine and packaging machine. The configuration of small-scale organic fertilizer equipment belongs to medium and low configuration. Whether it is capital investment or personnel configuration, generally, small-scale organic fertilizer equipment is acceptable to ordinary processors, and the quality of organic fertilizer equipment configuration directly affects the efficiency. Therefore, we should not choose small-scale organic fertilizer equipment blindly. We must choose a good small-scale organic fertilizer production line configuration.

The sheep manure Organic fertilizer production line mainly uses sheep manure and straw raised by farmers to produce biological Manure by crushing straw and fermenting pig manure together. The technological development of straw resources has become a major issue in ecological agriculture and sustainable development. Add the crushed straw into livestock excreta and other by-products, and then add biological bacteria. After more than ten days, harmless and high-quality Manure can be produced, which solves the problem of straw treatment that has puzzled agricultural production for many years.

The production line of sheep manure Organic fertilizer with an annual output of 100000 tons is basically a granular Organic fertilizer production line process, because it takes a certain time for a large-scale Organic fertilizer processing production line like 100000 tons to maintain fertility, facilitate transportation and other conditions from transportation to storage to sales. Undoubtedly, granular Manure with moderate hardness is more convenient for storage, transportation and fertility maintenance. Therefore, the production line of Organic fertilizer with an annual output of 100000 tons adopts the processing technology of granular Organic fertilizer production line. Such production line of Organic fertilizer needs to purchase fermentation, flip, smash, granulation, drying, cooling, screening, coating and packaging.

When it works, two rotors with opposite rotating blades stir in the middle. Due to the multiple special angles of the blades, regardless of the shape of the material. What is the size and density. Can mix quickly and effectively. Adopting a lower door for fast unloading speed and minimal residue.

Step 4: Equipment for manufacturing Organic fertilizer granules from cow dung. Disc granulator, Organic fertilizer agitating tooth granulator or new type agitating tooth rotating three combination granulator are used to granulate materials.

Step 5: The drum drying equipment uses a Organic fertilizer dryer to further remove moisture from the granulated particles to meet the standard requirements of Manure moisture content.

Step 6: The drum cooling equipment uses a cooling machine to cool the dried particle material, which helps to ensure the quality of particle storage.

Step 7: The screening and recycling system outputs granular materials from the granulation and forming system, which have certain differences in particle size and require screening and grading. The rotary screening machine requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device. It is recommended to equip an automatic material return system to screen unqualified large and small particles, transport them out through a belt elevator, re crush them, and then send them to a granulator for further granulation, which helps to improve the continuous operation capacity of the production line.

Step 8: Granular coating equipment. The coating machine is composed of a screw conveyor, a mixing tank, an oil pump, a main engine, etc., and is used for powder or liquid coating technology. It can effectively prevent the caking of composite fertilizers. The host is equipped with a polypropylene lining or acid resistant stainless steel.

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.

Chicken manure is a relatively high-quality Manure, which contains about 1.63%, 1.54% and 0.085% of pure nitrogen, phosphorus (P2O5) and potassium (K2O).
