Bolt-In Angle Hold-Downs for Troughs
Introduction
Screw conveyors are used throughout lime, limestone, and mineral processing. Most screw conveyors require hanger bearings to support each screw section. Hard iron bearings work well when conveying lime and limestone. However, dolomite is very abrasive and can cause premature wear on hanger bearings. The Maintenance Supervisor at a lime producer wanted to eliminate hanger bearings in several screw conveyors handling dolomite. Working closely with the plant, KWS redesigned the screw conveyors to utilize close-coupled and clocked screws, abrasion-resistant trough liners and bolt-in angle hold-downs.
