Rotary elevator

Rotary table hoist is a large-scale mechanical equipment transported by changing potential energy, such as mine hoist, dam passing hoist, etc. Broadly speaking, elevator, crown block, winch, car stabilizing, crane, hoist, etc. can be called hoist. Hoist generally refers to large-scale mechanical equipment with large power and strong lifting capacity.

It is used to vertically lift block granular materials such as limestone, coal, gypsum, clinker and dry clay passing through the crusher, as well as powdery materials such as raw meal, cement and pulverized coal. According to the speed of hopper operation, bucket elevator can be divided into three forms: centrifugal unloading, gravity unloading and mixed unloading.

The bucket speed of centrifugal unloading is fast, which is suitable for conveying powdery, granular, small block and other materials with small grinding and chipping; The bucket speed of gravity unloading is slow. It is suitable for conveying massive, high specific gravity and high grinding materials, such as limestone, clinker, etc. The traction components of bucket elevator include ring chain, plate chain and belt. The structure and manufacture of the ring chain are relatively simple, and the connection with the hopper is also very firm. When conveying materials with high grinding and chipping, the wear of the chain is small, but its self weight is large.

The plate chain has a firm structure and light weight. It is suitable for hoists with large lifting capacity, but the articulated joints are easy to be worn. The structure of the belt is relatively simple, but it is not suitable for conveying materials with high grinding and chipping. The material temperature of the ordinary belt is not more than 60 ° C, the allowable material temperature of the steel rope belt is 80 ° C, the allowable material temperature of the heat-resistant belt is 120 ° C, the ring chain The temperature of materials transported by plate chain can reach 250 ° C.
