The crusher usually serves to reduce the size of large stones into small stones or rock dust. It can also be used to reduce the size or change the shape of waste so that it can be easily recycled or disposed of. Generally used on large sites, the crusher also reduces the size of a solid mixture of raw materials.

The choice of a crusher depends on the material to be treated. It is therefore recommended to pre-test the materials to be treated in a laboratory. This test collects vital information and thus avoids costly errors. The percussion crusher is for example disadvised for a material having a high abrasion index. It is also important to test the site to gather all the necessary information.

It is essential to check the crushing chamber before starting the machine. This makes it possible to see if the crusher contains iron ores which ensure its starting. Indeed, large pieces of ore can be trapped at the discharge opening when the crusher is not turned on often. In this case, you can exclude large pieces using a hook. Furthermore, it is essential to regularly monitor the operation of the various instruments as well as the lubrication of the lubrication points.
