The hammer of the crusher is in direct contact with the material, so the consumption of the hammer has been too large. The main damage form of the hammer is loosening and breaking, not normal wear and tear. The loosening and breaking of plate hammer can break bolts and other plate hammers lightly, damage the rotor body and counterattack frame, break the shaft of the rotor body heavily, tear the rotor body, and consume a lot of plate hammer. In order to solve this problem, the rental manufacturer of mobile gravel crusher will introduce the measures to reduce the consumption of slab hammer of gravel crusher in this paper.
1. Make the best use of the board hammer with good quality.
In view of the quality problem of the plate hammer, Songyuan Industry suggested that the original stone crusher factory should be chosen as the plate hammer, which basically meets the quality requirements.
2. Re-manufacture of Bolt Mould
The elliptical head of the bolt can be in good contact with the contact surface of the hole of the plate hammer. At the same time, the thickness of the thread teeth of the bolt is controlled within the allowable size. The unloading groove is processed at the end of the thread to prevent stress concentration and fracture.
3. Strengthen the Management of Use and Maintenance
First, when plate hammer is installed, the moulding sand and burrs of bolt holes and grooves of plate hammer must be cleared so as to make the connection fit smoothly; secondly, when fastening plate hammer bolts, the elliptical head should be hammered while fastening; thirdly, the bolt tightening situation should be checked in time about half an hour after operation, and then the nut and thread should be spot welded after tightening to prevent loosening.
4. Material should meet equipment requirements when feeding
Before feeding, the operator should first read the crushing range of the equipment carefully, because different crushers have different hardness of crushed materials, and materials should be treated beforehand before crushing chamber to reduce the viscous and moisture content of materials.
