HGMS1000/1500 series medium-sized low speed granulators is suitable for crushing large scrap and inferior products in auto parts, home appliances, daily chemical packaging and other industries. It is especially suitable for crushing hollow materials such as plastic bottles, plastic barrels and other blow-molded products. Its knives are arranged in a V shape, which can grab the crushed materials in the center of the crushing cavity and prevent the materials from sticking to the side walls of the crushing cavity. The design of the stepped rotor makes the machine only have one tool for cutting at any time when crushing materials, which increases the cutting torque of the machine. We can select blowers, suction machines, etc. for crushing and recycling, or select conveyor belts to build a medium and large-scale automatic crushing and recycling system.
