The cells transporting the hot material - which are traditionally moved by chain - move by belts that are reinforced by steel wires and can be supplied in widths ranging from 630 mm to 1,400 mm. Plates are fastened to the outer sides of the cells to protect the belt from the hot material. Even if there is an unexpected material overflow on the belt in the material feeding area, the belt does not come into contact with the hot material. Compared to a chain, the belt has a lower weight which enables large lifting heights. With up to 1,300 m3/h and running speeds of up to 0.6 m/s, the belt apron conveyor reaches a higher conveying capacity than the conventional apron conveyor with chain. The entire belt lies with its surface on the drive and return pulley, thus, the unwanted polygon effect caused by the chain is avoided. This ensures quiet running and low noise emission, and avoids additional load by vibrations and noise to the plant and the adjacent buildings. Thanks to the compact and narrow design of the belt apron conveyor, the total project cost is reduced.

The BEUMER belt apron conveyor enables angles of inclination of up to 45°. The use of a belt avoids wear of the traction element. Lubrication of the traction element is not required. This represents a contribution to the environmental protection. The BEUMER belt apron conveyor is first choice for system modernisations. Thanks to faster conveying speeds, higher quantities of material can be transported while keeping the existing conveyor frames and steel bridges.
