For different materials and applications, the solid waste pre-treatment crusher performs its function through mutual shearing, tearing, and squeezing between the cutter heads to achieve the purpose of reducing the size of the materials. It is featured by low speed, large torque, high efficiency, high wear resistance, and low costs of operation and maintenance. It is widely applied into the crushing pretreatment of domestic waste, kitchen waste, hazardous waste, bulky waste, garden waste, scrap tires, electronic waste and other materials, thereby promoting the mechanized and pollution-free treatment of domestic solid waste.
