Reasonable ratio of raw materials is the basis to improve the ball formation rate
Single chemical fertilizer can not meet the needs of various nutrients of plants. NPK fertilizer production line mixes and granulates different nutrients to improve fertilizer efficiency. So how to improve the pelletizing rate of fertilizer? 1. Reasonable match of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: about 30% - 40% of the raw materials with 100-60 mesh, about 35% of the raw materials with 60 mesh to 1.00mm diameter, and about 25% - 30% of the small particles with 1.00-2.00mm diameter. The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the proportion of high fineness materials is too high, and it is easy to cause the bad problems such as too large particles, irregular particles and material wall sticking due to the good viscosity. 2. The reasonable collocation of cohesive materia...
