How to extend jaw crusher's life Time：2017-09-12 10:22:49

First selection: jaw plate material can select white cast iron. Large white cast iron hardness, good wear resistance, is easy to source and cheap; drawback is brittle, easily broken, the life is short. In order to improve the life of jaw plate, the material better uses more than 12% of manganese steel manganese, commonly used is ZGMn13. The disadvantage manganese is more expensive, but the service life, cost and other aspects of general considerations, ZGMn13 has longer life than white cast iron, and lower cost.

Then assemble: breaking plate must be firmly attached to the jaw plate should pad level between the two, with a soft metal (such as lead, zinc, etc.) between the plate and the jaw crusher jaw crusher for pads, and with bolt. When crusher works, broken plate should not have loose, or it is easy to break or wear plate, reduce the life of broken plates. So, be sure to install the breaker plate when assembled, thereby extending the life of the breaker plate.

The last is Precautions during use: the broken plates and material direct role, a great crushing force, jaw crusher particularly when broken material hardness greater, resulting in broken bolt installation vibration plate, nut loose, so the breaker plate and generate increased wear and tear a great noise, serious broken off or broken board makes equipment downtime, affecting the normal production. In such cases, just before starting the tightening bolts and nuts are not completely solve the problem, according to the actual situation at the scene to analyze specific issues, trying to take practical approach to problem solving.
