What kinds of granulating machines can be used in the granular fertilizer production plants?

At present, the use of organic waste to produce organic fertilizer through biological fermentation has been rapidly developed in my country, because it can realize the harmless and resourceful treatment of organic waste. However, most of the organic fertilizers obtained by biological fermentation are in the form of coarse powder or irregular small pieces, which are very inconvenient to use, especially unfavorable for large-area machine-sowing. The following content shows how to use powdery material into spherical granular organic fertilizer.

 1. Some manufacturers use ttraditional disc pelletizer or drum granulation machine, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture <15%) and pulverize it into very fine (more than 100 mesh) powder , and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer added in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, because the organic fertilizer in the processing process will be first sufficient precipitation is crushed, water is added to granulate and then dried, repeated many times, so the processing cost is quite high, and due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation and machine sowing.

       2. There are also some manufacturers who first dry the coarse powder or irregular small pieces of organic fertilizer to a moisture content of only 20-25%, and then use a flat die extrusion granulator or a counter-roll extrusion granulator to dry the fertilizer. The organic fertilizer is extruded into columnar or flat spherical particles. Although this method is more convenient to use, the fluidity is not very good, it is not suitable for machine sowing, and the appearance is poor and the appearance is not good.

3. There are also some manufacturers who extrude coarse powder or irregular small pieces of organic fertilizer into short columnar particles with a flat die extrusion granulator (due to high moisture and high fiber content, the columnar particles also have certain characteristics. Plasticity), then polished and formed into spherical particles, and then the spherical particles are dried, cooled and screened to obtain qualified particles. This method does not require treatment of raw materials, the order of moisture is reduced, and the production cost is greatly reduced, but this method also has some fatal. The weakness is that the organic fertilizer is easy to be arched, easy to block and easy to bond equipment, and at the same time, the output is small and the power consumption of the extrusion process is high.

       Therefore, in summary, the use of collision granulator to produce organic granular fertilizer has the advantages of low production cost, uniform product particle size, high strength, good fluidity, favorable for long-term storage and transportation, and suitable for machine sowing. That is to say, the performance of the products produced in this way is very good.

Fertilizer production technology

Image
   Fertilizer production technology Here fertilizer production main refers to organic and compound fertilizer production. As we all know, fertilizer refers to a type of material that provides one or more essential nutrient elements for plants, improves soil properties, and improves soil fertility. It is one of the material foundations of agricultural production. So how to produce fertilzier? We will introuduce organic and compound fertilizer production technology. How to manufacture organic fertilzer? In summary, the organic fertilizer production process roughly includes: raw material selection (animal manure, straw, sludge, grass charcoal, etc.) → fermentation treatment → ingredient mixing → granulation → cooling and screening → metering and sealing →  finished product storage. 1. Select raw material. The raw materials of organic fertilizer production are vairous. You can use animal manure, straw, you can also use tea residue, biogas residue or sugar ...

The function of groove type compost turning machine in organic fertilizer production line

Image
In the organic fertilizer production line, the fermentation process of organic fertilizer is a very important link. The success of organic fertilizer fermentation directly determines the quality of organic fertilizer after granulation. The granulation of organic fertilizer mainly refers to the process of fermentation, throwing, crushing, drying, cooling and granulation of livestock manure after adding biological bacteria. There are mainly two types of tipping machine, one is trench type, the other is mobile type, and the other is mobile type, which covers a large area. Generally speaking, after the biological fermentation tank is built, the harmful bacteria in animal manure can be eliminated by adding biological bacteria, and then heating up quickly, deodorizing, and eliminating the harmful bacteria in the manure of livestock and poultry. Generally speaking, the tank type overturning machine is used to turn and toss several times a day, so that the unfermented materials are completely...
