1. Bucket Elevator
The bucket elevator is a versatile conveying equipment designed to lift materials from lower levels to higher elevations. It is ideally suited for vertically transporting solid block materials and small particle materials like limestone, coal, gypsum, clinker, dry clay, cement, coal powder, and more. Materials are fed into the hopper through a vibrating table and are then continuously lifted upward by the bucket elevator. The conveying speed can be adjusted to match the desired capacity, and the lifting height can be customized to meet specific requirements. At Sprint Drives, we offer two types of bucket elevators: the NE Series and the TGD Series, each distinguished by its unique traction method.
