Compound fertilizer double roller granulator adopts dry rolling technology to compress powdery materials with water content less than or equal to 15% into flakes or lumps, and then through crushing and screening process, the flakes and lumps can be turned into granular materials meeting the use requirements. The fertilizer granulation machine has the characteristics of less investment, high efficiency, superior performance and convenient use. The double roller dry process is used for compound fertilizer granulation, and the dry powder materials are directly pressed into granules at room temperature. It can not only produce multi-element compound fertilizer and single fertilizer based on ammonium bicarbonate, urea, ammonium chloride, ammonium phosphate and potassium chloride, but also suitable for the production of organic fertilizer, magnetic fertilizer and rare earth fertilizer.

Application scope of the double roller granulator:
Potassium sulfate, potassium chloride, potassium magnesium fertilizer, NPK compound fertilizer, potassium nitrate, ammonium chloride, monoammonium phosphate, heavy calcium, superphosphate, diammonium phosphate, ammonium sulfate, phosphate rock powder, etc.
