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.
AggregatesThere are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes. 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.Learn More
Construction AggregatesConstruction aggregate is typically medium or coarse materials like granite, limestone or trap rock, sand, gravel, slag or recycled concrete. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.Learn More
Crushed StoneCrushed stone is a versatile product that can be used in a wide range of applications from construction to road building and even agriculture. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.Learn More
Sand & GravelAggregates, when gathered, may contain clays, silts and other deleterious material that needs to be processed out for commercial-grade products.Learn More
Surface MiningSurface mining involves removing soil and bedrock to reach resource deposits. The most common types of surface mining are strip and open-pit mining.Learn More
