Selection of equipment for producing compound fertilizer granulator

2022/10/09

 Compared with chemical fertilizers, NPK compound fertilizers have high nutrient content, few side components and good physical properties, which can promote the improvement of crop yield and quality. Compound fertilizer refers to two kinds of chemical fertilizers containing at least three components of nitrogen, phosphorus and potassium. Compared with base fertilizer, its production process is more complicated, and the production of chemical fertilizer is gradually systematic and diversified. Special compound fertilizers are becoming more and more popular. It can boost the yield and quality of crops.

When selecting production equipment, compound fertilizer organic fertilizer equipment or organic fertilizer organic fertilizer equipment, the same output, in the npk production line, organic fertilizer equipment generally considers high water content, strains are not resistant to high temperature, and the model is generally larger than the compound fertilizer model Some. There are 4 types of general organic fertilizers, pure organic fertilizer, organic-inorganic compound fertilizer, bio-organic fertilizer, compound microbial fertilizer.

Disc granulation or drum granulation is the principle of the granulation method. In the npk fertilizer manufacturing process of inorganic compound fertilizers, this granulation method is very common and practical, but for organic fertilizers, because organic compost is in after fermentation, the moisture content is generally about 30%, and the compost has coarse particle size, more fibers, and more agglomeration. It is difficult to agglomerate into granules when using disc or drum granulation methods.

The tooth stirring organic fertilizer granulator is one of the link equipments in the organic fertilizer industry. It is suitable for large-scale manufacturing of cold and hot granulation and high, medium and low concentration compound npk fertilizer production line.The working method is wet granulation of agglomerates. After a certain amount of water or steam, the chemical feedback of the basic fertilizer after the humidity adjustment in the cylinder is sufficient. Under the premise of a certain liquid phase, with the help of the twisting action of the cylinder, the material particles are formed.
