Apron Feeders

Overview

Osborn apron feeders accurately control the feed rate to prevent surge loads to the primary crusher or other processing equipment. 

These feeders feature a rugged, heavy-duty construction and are designed to handle feed sizes of up to 60” (1,500 mm) where no fines removal is required or where fines are removed by a separate vibrating grizzly. The apron feeder is built to withstand wet, sticky or clay-like material and handle it with ease. These feeders can be installed in a horizontal position or inclined up to 15-degrees. 

Applications

  • Aggregates

    There are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes of aggregates. Processing these materials typically requires various steps including reduction and sizing and also may include dewatering and sorting. Producers can use a variety of crushing, screening, dewatering and conveying equipment to meet their desired specifications.

        • Sand & Gravel

          Sand and gravel are aggregates that are gathered from naturally occurring deposits. These aggregates, when gathered, may contain clays, silts and other deleterious material that needs to be processed out for commercial-grade products. Reduction and sizing can be accomplished with a variety of crushers and screens. Once the material is accurately processed, it can be used for road building, construction materials and a variety of other applications.
