Mainly in case of failure after aging liner wear resistance decreased ability to fight, often caused by accidents liner was shot down, resulting in sealing performance of crusher dust have a greater decline. Housing maintenance is the primary means regular liner, it was discovered the timely replacement of aging, but also pay attention to regular checks liner screws, loose screws to prevent the accident off the liner. Proposed liner screw nuts are good effect.

Rotor Maintenance:

Rotor fault mainly in the wheel wear is more serious. New Building Materials Branch of the rotary crusher maintenance of the following methods.

Thickening on both sides of the rotor wheel, select resistant materials:

Counterattack hammer crusher machine, whether the production capacity of the rotor wheel size and quantity, in general, on both sides of the rotary dial in the rotor wear the most serious, is the focus of crusher maintenance. Thickened by both sides of the dial the appropriate way to improve the wear resistance, but also to prevent distortion when welding repair. New building materials branch thickness 12mm rotary switch from the original 20mm, the material is changed to the steel plate 16Mn 65Mn steel. Significantly improved wear resistance.

Repair welding on the dial to:

Even if the increase in the thickness of the dial and change the material, but still can not wear full control dial, or routine maintenance is often indispensable to the case of new building materials branch is taken regularly for maintenance of equipment for welding and rotary coating. Specific steps are missing part of the first wheel wear resistant iron chromium electrode for repair welding of boron, so that part of the wheel as much as possible to restore the original shape of wear, and then use the tungsten carbide electrode wear coating on the welding part. Tungsten electrode wear better, but expensive, therefore taking into account the cost of repair welding after the first coating using the repair process.
