Heavy-Duty Ultra Force Mechanical Feeders are available in 11 models with capacities to 2,500 tons per hour. The long stroke and low frequency of these rugged machines move high volumes of bulk material. Tray sizes up to 96 in. wide and 144 in. long are available. Special sizes can also be provided. The feeders utilize optimized steel-coil drive springs for high efficiency and performance. These units are ideal for high temperature applications where elastomeric drive springs cannot perform.
