With the rapid development of animal husbandry and planting, a large amount of livestock and poultry manure produced by large-scale farming has become a source of pollution if it is not disposed of in time. How to control these pollution sources from the source and utilize them rationally as soon as possible? Combining various factors, the ideal way is to use various organic fertilizer npk fertilizer production line and their processing equipment to recycle and ecologically utilize these wastes.
Composting is mainly divided into aerobic composting and anaerobic composting. At present, aerobic composting is mainly used. The composted manure has more stable nutrients, is more conducive to crop absorption, and can improve soil conditions. Therefore, farmers, small and medium-sized farms or farms mostly use this organic fertilizer equipment treatment mode.
The most common types of granulation are double roller granulator, disc granulator, tooth stirring granulator and drum granulator. The granules produced by each granulator are different, and the applicable materials have certain requirements. , the type of granulator can be determined according to the selection of raw materials.
In the organic fertilizer npk manufacturing process, the dryer dries the excess water in the organic fertilizer particles, which is convenient for material storage and not easy to deteriorate. In the production process of biological fertilizers, not only the water content of the granules after forming generally exceeds the index and needs to be dried at low temperature, but also the water content of the organic raw materials after fermentation is about 30% to 40%, and the water content of the granules after granulation is generally 15%between % and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. The drying section is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.
