The belt filter press from Charter Machine fixes the steering roller on an independent beam that is then set on a center pivot point. That means when the steering cylinder is attached to one end and moves, both sides of the steering roller move, which means less belt stretching and more belt life — more than 4,000 hours. Less maintenance is required, leading to more consistent cake solids performance from even tensioning and belt stretching. This design is used on the entire line of thickening and dewatering equipment. 732/548-4400; www.chartermachine.com.
