Elevator (well elevating conveyor/Elevator) is a large-scale mechanical equipment that transports by changing potential energy, such as mine hoist and dam-over hoist. Broadly speaking, elevators, cranes, hoists, stable cars, cranes, hoists, etc. can be called hoists. Hoist generally refers to large-scale mechanical equipment with large power and strong lifting capacity. The flexible part is dragged by the power machine to move the steel wire rope and the transported goods up and down to complete the transportation process. The steel wire rope is an indispensable important part of the lifting machinery. The main varieties are phosphate coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, smooth Wire rope, etc.

Bucket elevator is a kind of mechanical conveying equipment with fixed device. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It can be widely used in feed mills, flour mills, rice mills, oil plants of various sizes Upgrading of bulk materials in factories, starch plants, grain depots, ports and terminals, etc.

The bucket elevator is used to vertically lift the granular materials such as limestone, coal, gypsum, clinker, dry clay and other powder materials passing through the crusher, as well as raw materials, cement, coal powder and other powder materials. According to the speed of the hopper, the bucket elevator can be divided into three types: centrifugal discharge, gravity discharge and mixed discharge. The centrifugal discharge bucket has a faster speed and is suitable for conveying powder, granules, small blocks and other small abrasive materials; the gravity discharge bucket has a slower speed and is suitable for conveying bulk and larger specific gravity , Grinding materials, such as limestone, clinker, etc. There are several types of traction components for bucket elevators, such as ring chain, plate chain and adhesive tape.

The structure and manufacture of the ring chain is relatively simple, and the connection with the hopper is also very strong. When conveying materials with high abrasiveness, the wear of the chain is small, but its own weight is large. The plate chain structure is relatively strong, the weight is light, and it is suitable for the hoist with large lifting capacity, but the hinge joint is easy to be worn, the structure of the tape is relatively simple, but it is not suitable for conveying materials with high abrasiveness. The temperature of the ordinary tape material does not exceed 60 ℃, the temperature of the material allowed to reach 80 ℃ by the steel tape, and the temperature of the material to 120 ℃ by the heat-resistant tape, the temperature of the material transported by the ring chain and the plate chain can reach 250 ℃
