The rotor comprises a rotor frame, shaft, turntable, plate hammer, hammer plate fastening device. The thick steel plate, thick wall tube, welding and casting, processing welding (for balance ), in contact with the material is welded on tungsten carbide hard alloy wear resistant material. Rotor mass should be focused on the outer edge, increase the momef inertia.

The main shaft and the rotor flat key connection, and has the advantages of simple structure, convenient assembly and disassembly, neutral good, suitable for high speed, under variable load, impact.The spindle is the main part of the rotor, the impact force which will bear. Therefore, the material has high toughness and strength. Usually with a round section, and a flat key connection and other parts.

The counterattack plate two, paragraph three broken-line back plate. An adjustable, one is fixed. The adjustment of a lean is installed in the box body of the screw rod device.Plate hammer crusher wearing parts, so his resistance in that its service life is very important. So the use of KmTBCr26 of high chromium cast iron manufacturing plate hammer, its service life is much better than the high manganese steel material,. Due to the adoption of high chromium cast iron material, impact crusher can break 350MPa of various materials.

Impact crusher plate hammer various shapes, select board hammer shape principle, easy manufacture and fastening, increased service life. This design choice of strip-shaped plate hammer, hammer plate by bolts and plate hammer seat. Plate hammer seat belt tenon block, can use the tenon block work under plate impact hammer, avoid shearing bolt, improve the reliability of bolt connection.
