Bucket elevator is used for vertical lifting through the crusher limestone, coal, gypsum, clinker, dry clay and other granular material and raw materials, cement, pulverized coal and other powdery materials. According to the speed of the hopper running different, bucket elevator can be divided into: centrifugal unloading, gravity-type unloading and mixed-type unloading three kinds of forms.
Centrifugal unloading bucket speed faster, suitable for conveying powdery, granular, small block, such as small-cut material; gravity-type unloading bucket speed is slow, applicable to the delivery of massive, large proportion of the material, such as limestone, clinker and so on. The traction component of bucket elevator has several kinds of ring chain, plate chain and tape. Ring chain structure and manufacturing is relatively simple, and hopper connection is also very strong, conveying large-scale material, the chain wear small, but its heavy weight. The structure of the plate chain is stronger, the weight is lighter, it is suitable for the hoist with large lifting capacity, but the hinge joint is easy to wear, the structure of the tape is relatively simple, but it is not suitable for conveying large material, the ordinary tape material temperature is not more than 60°c, clamp steel wire tape allows material temperature up to 80°c, heat-resistant adhesive tape to allow material temperature up to 120°c, ring chain, plate chain conveying materials temperature can reach 250°c.
