Hoists are large mechanical equipment that transport by changing potential energy, such as mine hoists, dam hoists, etc. Broadly speaking, elevators, overhead cranes, winches, stabilizers, cranes, hoists, etc. can all be referred to as hoists. Hoists generally refer to large mechanical equipment with high power and strong lifting capacity. The transportation process is completed by dragging flexible steel wire ropes and the transported goods up and down through power machinery. Steel wire ropes are indispensable and important parts of lifting machinery, mainly including phosphating coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes, smooth steel wire ropes, and so on.
Bucket elevator is a fixed mechanical conveying equipment mainly suitable for continuous vertical lifting of powder, granular, and small materials. It can be used for lifting bulk materials in various scale feed factories, flour factories, rice factories, oil factories, starch factories, grain depots, ports, and other ports.
The bucket elevator is used to vertically lift block and granular materials such as limestone, coal, gypsum, clinker, dry clay, as well as powder materials such as raw materials, cement, and coal powder that pass through the crusher. According to the different speed of the hopper operation, bucket elevators can be divided into three forms: centrifugal discharge, gravity discharge, and mixed discharge. The centrifugal unloading bucket has a fast speed and is suitable for conveying materials with small grinding properties such as powder, granular, and small pieces; The bucket speed of gravity discharge is relatively slow, suitable for conveying block shaped, high specific gravity, and high grindability materials, such as limestone, clinker, etc. The traction components of bucket elevators include ring chains, plate chains, and adhesive tapes. The structure and manufacturing of the ring chain are relatively simple, and the connection to the hopper is also very strong. When transporting materials with high grinding ability, the wear of the chain is relatively small, but its self weight is relatively large. The plate chain structure is relatively firm and has a light weight, making it suitable for elevators with large lifting capacity. However, the articulated joints are prone to wear and tear, and the structure of the tape is relatively simple. However, it is not suitable for conveying materials with high grinding properties. The temperature of ordinary tape materials does not exceed 60 ℃, the temperature of steel rope tape materials is allowed to reach 80 ℃, the temperature of heat-resistant tape materials is allowed to reach 120 ℃, and the temperature of materials transported by ring chain and plate chain can reach 250 ℃.
