Belt bucket elevators are high-capacity machines designed for vertical conveying of biomass feedstock and processed materials in pellet/briquette plants, fuel preparation lines, blending systems, drying sections, and storage facilities.
Compared to chain bucket elevators, belt-type units can lift material to greater heights (up to 80 m in operation) while delivering higher throughput. This makes them an efficient solution for medium and large-scale plants with continuous material flow.
Belt bucket elevators perform particularly well when handling dry to moderately moist bulk solids commonly found in bioenergy: wood chips, sawdust, husks, pellets, agricultural residues, meal, and similar fractions. Their design enables gentle conveying with reduced pellet breakage and lower dust generation – important for consistent product quality and overall plant safety.
Belt bucket elevators are technically reliable systems that can be easily adapted to various operating conditions and types of materials. The elevators consist of several components that are essential for efficient operation.
Buckets. Buckets are the main working element of the bucket elevator. They are manufactured from mild steel, stainless steel, or plastic. Plastic buckets are suitable for grain and lightweight materials, while steel buckets are used for high-temperature and aggressive environments.
Drive mechanism. The buckets are driven by an elevator belt. The belt ensures smooth and quiet operation, easily wraps around the drive drums, and reduces dynamic loads.
Tensioning foot. Stable operation is ensured by a tensioning unit located in the lower part of the elevator, using either a threaded spindle or a gravity weight mechanism.
Due to their robust design, chain bucket elevators are intended for demanding operating conditions. They are suitable for conveying heavy bulk materials, products with high temperatures (above 100 °C), as well as aggressive or corrosive materials. These elevators ensure reliable operation at medium conveying heights and under increased mechanical loads.
Steel buckets in accordance with DIN 15234 are mounted to the rear wall and installed on two round-link chains, providing high strength and reliable performance when handling abrasive materials.
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 used for powdery products. A round-bottom housing minimizes dead zones and improves the hygienic design of the equipment.
To increase operational reliability and safety, bucket elevators can be equipped with additional accessories. These include an accumulation flap with a sensor for overflow protection in the elevator boot, as well as a speed monitoring system on the drive shaft, allowing early detection of malfunctions and prevention of emergency situations.
