How to determine the hammer of coal crusher failure

Coal crusher is a new type of equipment developed for the coal industry. Coal crusher is mainly designed to solve the difficult problem of coal with high moisture content. Coal crusher alias, also known as double-stage crusher, are efficient crushing equipment.

How to determine the hammer of coal crusher failure

Coal crusher hammer coal crusher is the most important part, and just look at the name of the coal crusher we can know what it means hammer, so the daily production must pay attention to the maintenance of the hammer And maintenance, and timely replacement of problems. Although the selection of materials in the hammer are made of wear-resistant compressive material, but after all, there are still periods of use, which according to the actual situation encountered in the work may be different, then how to determine the hammer's life to Now, what's the sign that the hammer can not be used anymore?

Coal crusher hammer in the work of the pre-surface and angular position did not produce wear and tear change, the hammer suffered the main impact force, the material to the impact of the hammerhead surface impact to the surface deformation and bump , But when the hammer is subject to wear and tear, because of its surface force surface decomposition, the normal force of the hammer face normal force impact on the hammer, and the tangential force of the hammer is washed good cutting effect. This will lead to coal crusher in the crushing of the material when the impact is not enough, broken serious low efficiency, extended production time.

Therefore, the role of coal crusher hammer transfer and wear changes that hammer failure is the main form of failure.
