Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It's an environment where equipment failure is often accepted as a cost of doing business.
