mineral processing vibration screening

Vibrating screens SKF

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.

Vibrating Screens for Mining Minerals General

Screens are available in a single motor design for elliptical motion or a dual motor design for linear screening and can work with either a horizontal or incline set-up. Each vibration method ensures the particles passing along the screen, if small enough, will have the opportunity to fall through the screen mesh between the start and end of the deck.
