The urea crusher is a core device for fertilizer raw material pretreatment, specially designed for crushing lumpy fertilizer raw materials such as urea, compound fertilizer and diammonium phosphate. Adopting the combined crushing principle of impact shearing and roll extrusion, it quickly grinds lumpy raw materials to the uniform fineness required for granulation. With a compact structure and excellent sealing performance, the equipment generates less dust and low noise during operation, effectively improving the production environment. Its discharge particle size can be flexibly adjusted by regulating roller clearance to meet the requirements of different granulation processes. It is also compatible with crushing wet materials with moisture content ≤55%, solving the problem of material agglomeration that plagues traditional crushers. The equipment is easy to operate, requiring only one person for daily operation, and has a long maintenance cycle. Its wear-resistant parts are made of forged high-alloy materials, extending the service life by more than 30% compared with ordinary equipment. It is widely used in small and medium-sized fertilizer plants, compound fertilizer production lines and organic fertilizer processing projects.
