Working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation. The shape of the particles is spherical, the sphericity is 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is 90%. The particle diameter can be properly adjusted according to the material mixing amount and the spindle speed. The lower the mixing amount, the higher the speed, the smaller the particles, and vice versa. Scope of application: This machine is especially suitable for granulation of light and fine powdery materials. The finer the basic particles of fine powder materials, the higher the sphericity of particles, and the better the quality of particles. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. In view of the particularities of granulation of organic fermentation fertilizers and organic fertilizer raw materials, such as livestock manure, manure, compost, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms and other urban domestic waste, the particles are particles.

The qualified rate of granulation of the new organic fertilizer granulator is as high as 80-90%, which is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the big ball rate is lower than 15%. The stepless speed regulation function of the machine can adjust the uniformity of particle size according to user requirements. This machine is suitable for direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing production cost. Now this new type of wet granulator for organic fertilizer is favored by the majority of users. The birth of new products, new production processes, energy conservation and environmental protection are all trustworthy.

Granulation method of organic fertilizer granulator

Organic fertilizer granulator is an important machine for the production of organic fertilizer, which plays a very important role in the organic fertilizer production industry. In our normal production activities, there are many ways to make organic fertilizer granulators. To help you better understand the process of organic fertilizer granulation, let’s explain the main granulation methods of organic fertilizer granulation.

The organic fertilizer granulator uses pressure to agglomerate solid materials, and then extrudes the materials through two counter rotating rollers, which are driven by eccentric sleeves or hydraulic systems. When extruding solid materials, first remove the air between the powder particles to rearrange the particles, thus eliminating the gap between the materials.

The extruding organic fertilizer granulator shall prevent the granular powder materials from being put into the extruding granulator, and then compress the powder materials by external force. Due to the different external force modes used, molecules are recombined to make the material appear as cylindrical particles. The whole production and extrusion process is mechanized without manual operation. However, stirring granulation mainly uses stirring to make the material round.

The thickness of the bulk product produced by the extruding organic fertilizer granulator is 5-20mm, and the surface density is 1.5-3 times of the feed. The large pieces are then sliced, crushed and sieved to obtain the desired granular product. Particles formed by pressure form hot spots at contact points to melt the material. After the temperature drops, the material cools to form a fixed bridge.

The above is a detailed introduction to the granulation method of organic fertilizer granulator. We can learn more about them. There are many methods for granulating organic fertilizer. Extrusion granulation can be said to be a common method, so we need to better understand this method. Only in this way can the granulating quality of organic fertilizer granulating agent be guaranteed.

 Compost turning machine is a necessary equipment in the production process of organic fertilizer. Its main function is to automatically turning the raw materials in the fermentation, so that the materials can better contact with the air, so as to improve the speed of material fermentation. On the other hand, it also plays a role in controlling the composting temperature.

The main purpose of turning over fermented compost is to evaporate excess water, so that the fertilizer and air are fully mixed, and the air is wrapped in the gaps of the compost. The decomposed fertilizer is suitable for the deep processing of fertilizer granulator. The smooth realization of composting fermentation depends on the distance the fertilizer travels in the air after being thrown. To analyze the effect of fertilizer throwing, the following assumptions are made for the thrown fertilizer particles:

1) When the fertilizer particles are thrown away from the Throwing Knife, the initial velocity of their motion is equal to the absolute velocity of the throwing knife speed and the involved velocity of the tipper

2) The movement of fertilizer particles has no influence on the movement of adjacent fertilizer particles

3) The trajectory of fertilizer particles is a continuous curve.

There are many types of organic fertilizer turning and throwing equipment on the market, and the actual use functions are also very different. The main selection factors are determined according to the customer’s terrain conditions, fertilizer production line technology, investment scale and other aspects. One of the most commonly used and lowest cost compost turning equipment is the trough turning machine. The smallest size is two meters in width. Of course, the large trough turning machine can reach more than 10 meters, and the price is more than 20,000 US dollars.

In addition to the above-mentioned trough turning and polishing machines, there are many types of organic fertilizer fermentation equipment, which are divided into two categories, trough turning and turning machines and walking turning and turning machines. The walking type turning machine is divided into crawler type and wheel type.

How to realize the green reuse of the double roller granulator resources is a problem that everyone is concerned about. On the other hand, the double roller granulator is an innovative product designed and produced under such a big premise. Why do you say that? I will give you a detailed introduction:

First of all, the double roller granulator is widely used to granulate some waste materials, such as coal powder, carbon powder, coke powder, carbon black, mineral powder, dust removal ash, lime powder and other metal mineral powder, as well as industrial recycled dust materials, iron casting plant dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding dust, etc.

It really realizes the recycling of resources and greatly protects the environment. In terms of environmental protection, the processing operation of this equipment adopts the non dry normal temperature process, which has high particle strength and is more obvious than other granulation methods, especially suitable for the occasions where the bulk specific gravity of products increases. More importantly, the mechanical transmission system of the double roller granulator is completely sealed in the machine body. As the powder materials complete the granulation process in the wet state, there is no discharge of the three wastes during the granulation of the roll to roll granulator and the subsequent process operation, which truly realizes green production. The double roller granulator has realized the green reuse of resources and has huge market potential.

The double roller granulator has the following advantages: 1. It operates circularly to realize continuous production and high output of finished products; 2. The material is forced to be compressed and shaped by mechanical pressure without any additives, so as to ensure the purity of the product. 3. The particle strength can be adjusted, and the finished product strength can be controlled by adjusting the pressure of the roller; 4. The extruding granulator is applicable to various raw materials, and the particle strength can be adjusted freely according to different materials. 5. Compact structure, convenient maintenance, simple operation, short process flow, low energy consumption, high efficiency and low failure rate.
