Generally speaking, organic fertilizer production can be divided into four steps: Fermentation - crushing - granulation - drying - packaging. These necessary steps also have more extended procedures, such as mixing, cooling, screening, coating, etc.
How to choose the organic fertilizer production line
customers often depends on the raw materials needed to make organic fertilizer. For example, in the crushing process, according to the water content of the raw materials, the selection of the grinder is also different. Generally, we should choose the semi wet material grinder to crush the raw materials with high water content. If it is dry materials, such as dry cow dung and sheep manure, we can choose the vertical grinder Comminution;
In the granulation process, according to the fiber size of the raw materials, we usually use the disc fertilizer granulator machine or drum fertilizer granulator machine
for the finer fiber materials, such as chicken manure; the flat film extrusion fertilizer granulator machine is used for the coarse fiber materials, such as cow dung, straw, etc.
In the drying process, if the budget is sufficient, we often recommend customers to install a cooler after the drying process. This is mainly to place the agglomeration caused by overheating of particles. In the later stage of granulation, there are coating and throwing processes to choose from. These are all "beauty" procedures for the finished products, making the particles more beautiful, neat and selling well.
