If the factors are not well controlled, it will affect the fermentation, either no fermentation, or incomplete fermentation, or long fermentation time, in fact, the inorganic fertilizer product formula and inorganic fertilizer should also be different according to different soils, different crop formulas are also different, if the fermentation is adequate, the effect is better than inorganic fertilizer, the cost is low, and it can improve the environment for plant survival, and it is a green fertilizer. Therefore, the difference between organic fertilizer equipment and inorganic fertilizer equipment is particularly important. Organic fertilizer equipment and inorganic fertilizer equipment is different, organic fertilizer equipment is mainly divided into two parts, fermentation part and production of granulation part. Among them, there is also a big difference between the production of granulation part and inorganic fertilizer part, because organic raw materials are different from inorganic raw materials. The production of inorganic raw materials can mainly be based on the chemical reaction of raw materials. If the formula is proper, the operation is skilled, and the pelleting rate is high, the production is relatively easy, while organic fertilizer raw materials are difficult to granulate even if the fermentation is better. Because the characteristics of organic raw materials are relatively light, rough, relatively low bonding rate, various organic raw materials have different characteristics, so the selection of equipment, should be particularly careful, otherwise it will not only affect the output, but also the appearance of the product is not beautiful. The selection of organic fertilizer granulator and fermentation compost turning machine should pay attention to several points: annual output, what kind of organic raw materials, what kind of fermentation method, mechanization degree, is the key factor in the selection of equipment.
