TH and HL type chain bucket elevators are suitable for vertical conveying of highly abrasive powdery, granular and small lumpy materials, such as grain, coal, cement, crushed ore, etc. The maximum conveying height is 40m. Its features are: simple structure, stable operation, scooping loading, mixed or gravity unloading. The rim adopts a combined sprocket, which is convenient to replace; the sprocket rim has a long service life after special treatment. If a gravity automatic tensioning device is adopted at the lower part, it can maintain constant tension to avoid slipping or chain jumping. At the same time, when the hopper is blocked, it has a certain allowance to effectively protect the moving parts, and the material temperature does not exceed 250℃. The TH type is designed and manufactured in accordance with the JB3926—85 Vertical Bucket Elevator standard and should be preferred. Except for the connection dimensions, the chain, sprocket and tensioning device of the HL bucket elevator are the same as those of the TH type.
