An organic fertilizer dedicated crushing machine is a new type of high-efficiency single-rotor reversible crusher with strong adaptability to material moisture content. It can process composted waste or other materials with moisture content ≤30% into powder. The particle size of the powder can reach 20-30 mesh, meeting the feed particle size requirements of general granulation equipment for fertilizer production. The resulting particles have a smooth surface, making it an ideal equipment for organic fertilizer production.
