Double shaft shredder is designed large torque shear equipment in order to break large hard materials. The equipment is widely used to tear up the bundles of material containing foreign matter or high hardness materials. The modular design of the machine box greatly reduces the cost of maintenance of the main components of the equipment,Save maintenance time,In the large-scale cutting equipment has a great advantage. 1. The frame is combinational structures, made from precision machined extra-thick sheet, slewing axis is forced, Lange-angle, hexagonal prism, the hopper is large-caliber, and substantial,so good-sized material is practicable. 2. Revolving knife is designed and processed particular in thickness, shape, arrange order and so on. 3. PLC control system, forward and reverse operate and stop automatically can protect the machine when the materials is too big and much. Operate safely, low-speed running, low noise, little dust. 4. The knife is made from special alloy steel, sturdy and durable.
