The apron feeder in the crushing line as the first stage of feeding equipment, widely used in the quarry crushing plant, cement, iron ore crushing line. As feeding device feeding limestone in the cement plant, apron feeder plays an important role in the production of cement. DSMAC have 15 years’ experience in mining equipments, and DSMAC apron feeders are used in cement plants, quarry plant in at home and abroad.
Apron feeders consist of two strands of tractor- type chain fitted with cast of fabricated pans. The chain is supported on standard tractor-type carrying rollers and plain rollers at the feeder’s return side. The equipment design is based on continuous operations, built to withstand high-impact loads and therefore suitable for coarse and abrasive materials, such as limestone, hard rock, iron ore, copper ore, and over-burden, among others. Krupp Materials Handling has engineered apron feeders with pan widths ranging from 800mm to 3,400mm, lengths as great as 30m, and capacities of up to 1000tph. Special designs allow inclinations of up to 28° from the horizontal. The drive system features fixed or variable speeds, with either a low-speed high-torque or high-speed low-torque hydraulic motor combined with planetary reducers or electro-mechanical drive units.
Apron feeder in cement plant
Recently, due to the new and heavier demands in cement manufacture, the major quarries of dry grain production have been forced to eliminate the clays, which highly contaminated their final product. The Atmos elliptic disk screen has proved to be a highly effective tool for them in this instance, being assembled next to the Atmos heavy-duty apron feeder they already have, in their installations.
