High performance belt bucket elevators are mainly used in low-maintenance continuous process applications for the transport of raw meal, cement, pulverised coal or other fine bulk materials (< 3 mm) with temperatures of up to 130°C. Conveying heights range from 10 to 150 m and conveying capacities are possible up to 1500 t/h. With the close bucket pitch in conjunction with the high speed (1 - 2,1 m/s) continuous material conveying is guaranteed with the minimum of spillage. A light duty version of the belt bucket elevator is available for low to medium conveying capacities up to 130 m3/h and reduced conveying heights of 10 to 65 m.
Aumund belt bucket elevators are characterised by steel-reinforced belts. A self-adjusting parallel tension device (prevents) maintains straight running of the belt. Longitudinal steel ropes form the traction elements. Together with the additional cross ropes, they form a rigid structure ensuring high resistance. In the elevator boot a bar-type drum ensures the guided return of the belt. Precise parallel guidance is obtained with the parallel tensioning device.
