The technology of Chain Bucket Elevators

Chain bucket elevators are technically reliable systems that can be easily adapted to various operating conditions and material types. The elevators consist of several components that are crucial for efficient operation.

Buckets. Buckets are the main working element of the elevator. They are made of mild steel, stainless steel, or plastic. Plastic buckets are suitable for grain and light materials, while steel buckets are used for high temperatures and aggressive environments.

Drive. The buckets are driven by an elevator chain, which provides high strength and reliability when conveying heavy materials.

Tensioning system. Stable and smooth operation is ensured by a tensioning unit located in the lower part of the elevator, using either a threaded spindle or a gravity weight system.

Pressure relief for dust explosions

During loading and discharge of the bucket elevator, dust is generated, which may form a potentially explosive atmosphere (ATEX). The elevators can be equipped with explosion pressure relief devices selected according to the operating conditions. The reinforced housing is designed to withstand reduced explosion pressure, ensuring safe operation of the bucket elevator.

Other Design Options. Bucket elevators can be manufactured with positive gravity discharge, which ensures gentle material handling and reduces wear. For abrasive materials, buckets with hardened front edges are used, while buckets with ventilation holes are applied for powdery products. A round-bottom housing minimizes dead zones and improves the hygienic design of the equipment.
