1. Applications
Bucket elevators are used to transport powdery, granular and small pieces of materials vertically or tilted.Advantages of bucket elevators: small cross-sectional dimensions allow for a compact conveyor system; large lifting height; good sealing, etc. Its disadvantages: high sensitivity to overload; hopper and traction components are easily damaged.
The bucket elevator can lift materials to a height of up to 80m (such as TDG type), and the general range is less than 40m. The conveying capacity is below 1600m3/h.Under normal circumstances, vertical bucket elevators are mostly used. When it cannot meet special process requirements, inclined bucket elevators are used.When the traction component of the inclined bucket elevator is too vertical, it is necessary to add a device to support the traction component, which complicates the structure. Therefore, the inclined bucket elevator is rarely used.
2.Classification
1) Different installation methods: vertical; inclined; vertical and horizontal
2) Different unloading characteristics: centrifugal type; centrifugal gravity type; gravity type
3) Different loading characteristics: extraction type ; flow-in type
4) Different types of traction components: belt type ; chain type (plate chain, ring chain)
5)The hoppers have different forms: deep bucket type ; shallow bucket type ; scale bucket (triangular bucket or trapezoidal bucket) type.
3. Main features
1) Small driving power
When the material is lifted, the inflow feeding, induced discharge, and large-capacity hopper intensive arrangement are used to almost eliminate the phenomenon of material return and excavation, so the ineffective power is small.
2) Wide range of improvement
The bucket elevator has few requirements on the type and characteristics of materials. It can not only lift general powdery and small granular materials, but also materials with greater grindability. It has good sealing performance and less environmental pollution.
3) Long service life
The design ensures that materials rarely scatter during feeding and unloading, reducing mechanical wear.
