The general process flow of organic fertilizer production line is: fermentation, crushing, mixing, granulation, drying, cooling, screening and packaging.
The main purpose of fermentation is to decompose the pathogens, eggs and other harmful substances in the organic fertilizer raw materials. The role of the tank tipper is to toss, promote oxygen, evaporate excess water, control the temperature of the pile, and avoid odor generated by anaerobic reaction, so as to achieve the purpose of rapid fermentation and shorten the fermentation cycle;
The reason for crushing after fermentation is that it needs to stand for about one week at the later stage of fermentation, which will produce certain caking phenomenon;
After being crushed by a semi wet material pulverizer, it will not jam and stir teeth when granulating in the organic fertilizer granulator, causing damage to the equipment. At the same time, the more uniform the powder, the more uniform the particles will be. In order to improve the nutrient content of organic fertilizer, certain n, K, P powder can be added, and then put into the organic fertilizer granulator after being evenly stirred by the horizontal mixer The results showed that the nutrient composition of the granules was uniform and the fertilizer efficiency was consistent;
I will not explain the purpose and function of ring die granulator here. The type of granulator is mainly determined according to the needs of customers (particle shape, output, etc.);
The main purpose of drum dryer and cooler is only one, that is to quickly evaporate excess water and reduce the difficulty of packaging;
After that, the semi-finished products and the powder are removed by the screening machine, and the qualified products are directly packed and bagged as finished products.
