ENDURON Excellent Comminution Equipment Solutions

Vibrating motion for a screen is provided by means of out-of-balance motors or geared exciters. Enduron® vibrating screens use high g-force geared exciters for machines wider than 1.8m (6') to provide the vibration motion required. The major part of the exciter drive is the housing, which is a cast metal enclosure and serves as an oil bath.

Shale Shakers In Oilfield Guide

The vibration of the shaker basket creates G-forces which help drive shear-thinning fluids such as drilling mud through the screens. Vibration also conveys solids off the screens. Most linear motion shakers operate in the range of 3 to 4 G's to balance throughput with screen life. G-force is a function of vibration frequency (rpm) and stroke ...
