Shielding bearings from silica dust

While the adverse effects of silica dust on human health are well documented, it is a less known fact that the product – often found in mining, quarrying, and recycling industries – can also have detrimental impacts on machine components. 

This was confirmed by engineers from BSC as they were studying the root cause of frequent bearing failures for one of their clients, a building waste recycling company. The bearings were installed at the two ends of the main shaft of an impact crusher that crushes large quantities of bricks and concrete blocks and is therefore exposed to dirt and dust ingress from the construction material.
