If you want to know how to choose organic fertilizer production line equipment, you must first understand the steps of organic fertilizer production. Generally speaking, organic fertilizer production can be divided into four steps: fermentation - grinding - granulation - drying - packaging, these necessary steps also have more extended procedures, such as mixing, cooling, screening, coating and so on. Choosing the right equipment is not difficult, often depends on the need to make organic fertilizer raw materials, such as in the crushing process, according to the different water content of raw materials to choose organic fertilizer crusher is different, usually high water content of raw materials we should choose half-wet material crusher to crush, if it is dry material, For example, dry cow dung, sheep dung, which we can use vertical grinder to crush; In the granulation process, according to the fiber size of the raw material, we usually use a disc or a drum granulator for finer fiber raw materials, such as chicken manure; The coarse fiber material uses the flat film extrusion granulator; For example: cow manure, straw and so on. In the drying process, if the budget is sufficient, we often recommend customers to carry a cooling machine after the drying process, which is mainly to place the caking phenomenon caused by overheating particles, in the late granulation, there are coating, throwing and other processes optional, these belong to the finished product "beauty" procedure, so that the particles are more beautiful, neat, full of appearance.
