At present, the rural development has been in the transition period, a large number of surplus labor in the countryside flow to the city, land circulation, towards large-scale intensive development, a lot of land has been contracted out to develop the tertiary industry. The acceleration of rural urbanization development has increased the rural machinery market and organic fertilizer equipment space, and more modern machinery and equipment will serve agriculture more. Compared with industry and service industry, the development of China’s agriculture is slow and backward, and this phenomenon of uncoordinated synchronization has also been attached importance by the state. In some European and American countries are basically in the form of farms, basically achieve agricultural mechanization, thousands of acres of rural areas may only need a few people to plant, fertilization can be used to spray, irrigation has modern irrigation tools, “foreign fruit picking is mechanical, because the artificial is very expensive, all artificial fruit is generally expensive, The future of agricultural mechanization is highly functional mechanization.” The organic fertilizer production line equipment involved in agriculture has great potential in the future, and China’s agricultural efficiency cannot be improved without mechanization. All kinds of machinery, organic fertilizer equipment, processing enterprises into agriculture, it is best to be as a service company, rather than their own participation in farming this scale is just right, and there will be no environmental pollution.
The centralized development of agriculture in the future will inevitably lead to the continuous progress and improvement of large machinery, and the continuous development of science and technology requires people to predict the future trend with an advanced vision, which is also what the managers of organic fertilizer equipment production enterprises should see. The realization of rural urbanization needs the support and support of the machinery industry, without modern organic fertilizer production equipment, planting equipment, agricultural product processing equipment, etc., the modernization of agriculture is out of the question. Opportunities and challenges coexist, the opportunity of the acceleration of the process of agricultural urbanization needs to be grasped by machinery and fertilizer production equipment enterprises, while many unpredictable changes in the future, but also need manufacturers to prepare for the rainy day, consolidate the foundation, in order to remain unchanged.

Fertilizer granulator machine is to be designed and used to produce the organic fertilizer granulator or compound fertilizer granulator.In the fertilizer manufacturing process,it is to be designed and equipped in the fertilizer manufacturing process to finish the granulation process.
In organic fertilizer production line,it is to be equipped with different type and series fertilizer machine to finish the production process.The fertilizer granulation machine has important features of organic fertilizer granulator:
1.The particles produced are apherical;
2.The content of organic matter can be as high as to realize the granulation of pure organic matter;
3.The organic particles can be embedded with each other under a certain force,so there is no need to add binder during granulation.
4.The particles are solid and can be screened after granulation to reduce the engery consumption of drying.
5.The organics after fermentation do not need to be dried,and the moisture content of raw materials can be 20-40%
And the flat die granulator machine is usually to be used in biofertilizer production line to finish the granulation process.In the bio organic fertilizer production,how to work of the flat die granulator machine.The screened raw materials are fed into the flat die granulator evenly,and the cylinndrical particles are extruded under the extrusion of the die. After extrusion and granulation,the organic fertilizer particles have moderate hardness and neat shape.The particles enter into the thrower,and rotate and rub with the inner wall of the thrower.The shape is smooth,the size is even,and it is easy to use.The temperature of flat die granulator is low in the process of processing,and it can be better maintain the internal nutrients of raw materials.After particle forming,drying and cooling steps can be omitted,and finishing can be continued. After drying, cooling, screening, packaging and storage.

Animal manure fertilizer making equipment processes raw materials into granular organic fertilizers through a series of processes including fermentation, crushing, granulation, drying, cooling, screening, and coating.

Chicken manure, pig manure, cow manure, sludge, etc. are treated harmless through composting and fermentation: Chicken manure and animal manure from breeding farms are mixed with filling materials in a certain proportion, such as straw powder, mushroom residue, medicinal residue, rice bran, grass powder, peanut shell powder, etc. After mixing, organic fertilizer fermentation strains are added, and the mixture is fermented and flipped. The pig manure organic fertilizer production line requires 10-15 days to mature, which can be odorless, odorless, and harmless. The compost is soft and yellow brown in color, There are gray white mycelium and about 45% organic matter in the pile. It has the functions of non-toxic and harmless, increasing yield, improving quality, promoting disease resistance and growth, fertilizing soil fertility, and improving fertilizer utilization. It is an ideal fertilizer for producing green food and developing ecological agriculture.

The characteristics of small livestock and poultry manure organic fertilizer production lines are:

1. Applicability and wide range of raw materials: suitable for direct granulation of fermented animal manure, sugar factory filter sludge, urban sludge, papermaking sludge, distiller’s grains, straw, peat and other coarse fiber organic waste with a moisture content of about 30%. It can produce pure organic fertilizer, organic inorganic fertilizer, and bio organic fertilizer with spherical particles.

2. High ball forming rate and microbial survival rate: The new process can achieve a ball forming rate of over 90-95%, and the low-temperature and high air drying technology can achieve a microbial survival rate of over 90%.

3. The process flow of organic fertilizer production line is short, and the operating cost is low. The organic raw materials used in this process do not require pre-treatment such as drying and crushing. The process flow is short, and the operating cost is low (if traditional granulation processes such as disc or drum are used, the organic raw materials with a moisture content of about 30% after fermentation need to be dried to below 13% and crushed to above 80 mesh, and the amount of organic materials added cannot exceed 30%).

The roller is also the most easily worn accessory in the granulation operation of the roller granulator. As the main part of material granulation, the roller skin is gradually worn and produces uneven particles. How to reduce the wear of the roller granulator is the most important thing.

Severe wear on the roller surface can affect the production efficiency of the roller granulator and the particle size of the finished product. In severe cases, it is necessary to stop the machine and replace the roller surface with a new one. How to reduce material wear on the roller surface through multiple efforts during equipment use? The main reasons for severe wear of the roller skin of the roller granulator are as follows:

1. Uneven feeding can easily cause uneven wear of the roller skin.

2. It is directly related to the material of the roller skin itself. The roller skin with poor material has poor wear resistance, corrosion resistance, and short service life.

3. The surface shape, specifications, dimensions, and operating conditions of the roller can have an impact on the machine.

4. Affected by the hardness, size, and shape of the processed material. Materials that are too hard, too large, or too irregular can easily cause uneven wear of the roller skin.

The reason for the wear of the roller skin of the roller granulator is that during the physical granulation of the roller skin, the roller surface will gradually wear out. Therefore, it is necessary to ensure that the material is evenly fed into the granulator along the length of the roller. If the feeding is uneven, circular grooves will appear on the roller surface, affecting the normal operation of the granulator, and the product particle size is uneven. When feeding, the feeder not only needs to feed evenly and continuously, but its length should also be consistent with the length of the roller.

Long term operation of the equipment inevitably results in wear on the roller skin of the roller granulator, which requires us to regularly shut down for maintenance. If we can repair it in advance when the wear reaches a certain level, can we avoid the need to replace the new roller surface in the future?

When the roller granulator is granulating materials, the roller surface will gradually wear out, ensuring that the materials are evenly fed into the granulator along the length of the roller. If the feeding is uneven, circular grooves will appear on the roller surface, affecting the normal operation of the granulator, and the product particle size is uneven. When feeding, the feeder not only needs to feed evenly and continuously, but its length should also be consistent with the length of the roller.

The wear of the roller surface can also increase the discharge port, so it is necessary to adjust the movable roller. When adjusting, it is necessary to keep the two rollers parallel to each other to prevent tilting. A pair of roller granulator with movable rollers installed on the rocker arm or hydraulic compensation device, which automatically ensures that the axes of the two rollers are parallel when the movable rollers move.

There is a grinding wheel installed on the rack. When there are pits or grooves on the roller surface, the roller surface can be ground and repaired on the machine without removing it, or directly repaired on the roller surface. This requires the installation of a welding device on the granulator. Some roller granulators are equipped with an automatic axial reciprocating movement device for the rollers, which ensures uniform wear and tear on the roller surface.

Rotary drum granulator is a kind of molding machine which can make material into specific shape. Rotary drum granulator is one of the complete sets of equipment in compound fertilizer industry, which is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer.

The working mode of rotary drum granulator is wet granulation. Through a certain amount of water or steam, the basic fertilizer can be fully chemically reacted after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the material particles will produce extrusion pressure and agglomerate into balls.

The production line process of rotary drum granulator includes raw material batching machine, fertilizer mixer machine, crusher, rotary drum granulator, particle dryer, particle cooler, coating machine for finished product, and quantitative packaging machine for finished product.

5. 5. Grain cooling: the temperature of the dried fertilizer particles is too high and easy to agglomerate. After cooling, it is easy to pack, store and transport.
6. 6. Particle classification: the cooled particles are graded. The unqualified particles are crushed and re granulated, and the qualified products are screened out.
7. 7. Finished film: the qualified products are coated to increase the brightness and roundness of particles.
8. 8. Packaging of finished products: bag the coated particles, that is, finished products, and keep them in a ventilated place.

The complete set of equipment for large-scale cow manure organic fertilizer production line is basically a granular organic fertilizer production line process. Because large-scale organic fertilizer processing and production lines like 100000 tons require a certain amount of time from transportation to storage and sales to maintain fertility and facilitate transportation, it is undoubtedly easier to store and maintain fertility for granular organic fertilizers with moderate hardness. Therefore, the organic fertilizer production lines with an annual output of 100000 tons on the market all use the granular organic fertilizer production line processing technology. Such processing organic fertilizer production lines require the purchase of a series of organic fertilizer equipment such as fermentation, crushing, stirring, granulation, screening and returning materials, and film packaging.

Supporting equipment and process for large-scale cow manure organic fertilizer production line:

1. Raw material fermentation: Various animal feces such as chicken manure, pig manure, cow manure, biogas residue, or raw materials that can be fermented or have fertilizer effects after treatment are prepared in proportion (according to market demand and soil testing results in different regions).

2. Raw material mixing: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles.

3. Raw material granulation: The evenly stirred raw materials are fed into a granulator for granulation (using drum granulators, extrusion granulators, and new organic fertilizer granulators).

4. Particle drying: The particles made by the organic fertilizer granulator are fed into the dryer to dry the moisture contained in the particles, increasing their strength and facilitating storage.

5. Particle cooling: The dried fertilizer particles have a high temperature and are prone to clumping. After cooling, they are easy to pack, store, and transport.

6. Particle classification: The cooled particles are classified, and the unqualified particles are crushed and re granulated to screen out the qualified products.

7. Finished product coating: Coating qualified products to increase the brightness and roundness of particles.

8. Finished product packaging: Bag the processed particles, which are the finished products, and store them in a ventilated place.

The principle of drum granulation is that materials rely on surface tension, an appropriate amount of liquid phase, extrusion force generated by rolling between materials, and small particles are taken as the core in the correct movement direction of materials in the granulator to absorb large particles and adhere to small particles and form balls during rolling. The higher the rolling frequency in a certain time, the higher the balling rate and the rounder the particles are after forming. 

Working principle of rotary drum granulatorr:

The rotary drum granulator drives the belt and pulley by the main motor, drives the drive shaft through the reducer, and works opposite to each other through the open gear installed on the drive shaft and the big gear ring fixed on the body. The material is added from the feed end of the rotary drum granulator through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles, and finally outflow through the discharge port. Due to the continuous entry of materials and the continuous rotation of the rotary drum granulator, mass production of organic fertilizer production lines can be achieved.

The organic fertilizer rotary drum granulator used in small and medium-sized fertilizer plants is a rotating circular granulator with a diameter of 1.2 – 2.4m and a length of 3 – 6m. A material retaining ring is arranged at the feeding end and the middle part of the simplified body, and the tail is smooth. The middle retaining ring of the organic fertilizer drum granulator divides the simplified body into two areas, the front area is the mixing granulation area, and the rear area is the particle polishing area.

The new fertilizer production line project should comprehensively consider the local resources, market capacity and market coverage radius. Generally, the annual output of small-scale new plants is 10000 tons (1.5 tons / hour), 20000 tons (3 tons / hour) and 30000 tons (4.5 tons / hour). The annual output of medium-sized factories is 50000-100000 tons, and that of large-scale factories is 100000-300000 tons.

The investment scale and scheme design need to be formulated according to the following conditions: characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, plant site conditions, selection of NPK fertilizer granulator, production automation degree, etc.

The material is added from the higher end, and the high-temperature flue gas and the material enter into the cylinder in parallel. With the rotation of the cylinder, the material moves to the lower end due to gravity. A lifting plate is welded on the inner wall of the cylinder to take up and drop the materials, and fully contact with hot air in the falling process, so as to achieve the purpose of drying.

4. The rotary cooler can reduce the moisture content while cooling a certain temperature. It is the same equipment as the dryer, except that the air is drawn from the head to the outside when used, so there is no need to seal the tail.

5. The drum screening machine adopts a combined screen, which is convenient for maintenance and replacement. The machine has a simple structure, convenient operation and stable operation.

Fruit pomace is the remaining fruit pomace after the water content of the fruit is extracted from the food, such as apple pomace, tomato pomace, pear, corn, grain, sugarcane, medicinal pomace, and other different types of pomace. Due to the economic added value of secondary processing benefits such as feed, the dried fruit pomace contains a certain amount of internal moisture. Before entering the fruit pomace dryer, the material needs to be thoroughly dehydrated in the dehydrator, Then enter a professional production and drying machine for operation, using a one-time countercurrent rotation method to reduce the moisture content to below 5%, without damaging the nutritional value of the original material, and without causing the problem of material burning.
