The rotor fault is mainly manifested in the serious wear of the rotating disc.New building materials branch to crusher turntable maintenance to take the following methods.Choosing wear-resistant material on both sides of the thickened rotor: no matter the production capacity of the hammer crusher and the number of the rotor turntable, the wear of the rotary disc on both sides of the rotor is the most serious in general, which is also the key point of the crusher maintenance.The wear resistance can be improved by thickening both sides of the turntable, and deformation can be prevented during repair welding.
Repair welding of the turntable: even if the disc is thickened and the material is changed, the wear of the rotary disc cannot be completely controlled.Routine maintenance is still indispensable. In general, the new building materials branch takes the method of repairing and coating the turntable regularly by the maintenance staff.The concrete operation steps are that the wear missing part of the rotary disc is first repaired with iron-chromium-boron wear resistance electrode to restore the original shape of the wear part of the rotary disc as far as possible, and then the welding part is coated with tungsten carbide wear-resistant electrode.Tungsten carbide electrode has good wear resistance, but its price is high. Therefore, the coating is used after welding first because of the cost.Maintenance process
