New AUMUND belt bucket elevator

AUMUND has developed a new belt bucket elevator for the vertical transport of course grained bulk material. The belt bucket elevator is configured for a grainage of 10 mm and a performance of 2000 tph. The growing presence in the fields of mining and minerals led to the development of a Coarse Grain Bucket Elevator (BWG-GK type). It is able to transport coarse grained material (up to 80 mm) with a performance of 1200 m³/h.

The tight, overlapping configuration of the buckets, and the fact that the belt will be completely covered by the buckets coarse material will be prevented from becoming jammed between the backs of the buckets. The plate screws developed for mounting the buckets differ significantly from conventional DIN plate screws and are constructed for longer belt endurance and a higher load. Therefore, further parts to increase the tension force at the bucket attachment are not necessary.

The carcass design of the AUMUND Bucket Elevator Belts combined with the AUMUND Bucket Attachment System guarantee a long lasting service life. The belt of the bucket elevator has been optimally designed for its attachments like buckets, profiled rubber edges and endless splices. Tightly packed cords made of high-tensile steel serve as tension members.

On the front and back side of the tension member, transversal steel belt reinforcements strengthen the belt. Contrary to reinforcements with textile mesh, the advantage of the transversal steel belt reinforcements lies with higher adhesion values between rubber and tension members. That ensures a durable connection of the particular belt layers even at higher temperatures.

Newly developed rubber compounds based on ethylene-propylene-diene-monomer (EPDM) make it possible to use AUMUND Belt Bucket Elevators in ranges of operation with a material temperature of up to 150°C possible. Endurance tests during daily industrial routine have indicated that EPDM belts are more durable against ageing than textile belts.
