According to the characteristics of material selection bucket elevator hopper form

- Apr 08, 2018-

Each part of the bucket elevator has an important role in the lifting process, in which the hopper becomes a key component of its carrying material. According to the difference of lifting materials, the shape and size of the matching hopper in the bucket elevator are also different, and it should be selected and used according to needs.


At present, there are mainly three types of hoppers commonly used. One is a deep bucket. Its characteristic is that the front edge is slightly inclined from the horizontal, and the depth is relatively large. Therefore, when the bucket elevator unloads dry, easy-to-flow, non-sticky This hopper is required for knotted and easily thrown granular materials such as dry sand and small pieces of coal.


The other is a shallow bucket, which is just the opposite of the deep bucket. The slope of the front edge of the bucket and the vertical section of the bucket is larger than the deep bucket and the depth is smaller. This bucket elevator hopper is mainly used to unload wet and poorly flowing granular materials such as wet sand and wet end coal.


From the structural characteristics of this kind of hopper, we can see that because of its small depth and large inclination of the front edge, the bucket bucket elevator can easily empty the material when it is unloaded. However, these two kinds of hoppers are only used for bucket elevators where the hoppers are arranged at intervals. Both the deep bucket and the shallow bucket have an arc-shaped bottom so as not to stick the material to the bottom of the bucket, so it is beneficial to unloading well.


In addition, there is also a pointed hopper with side guides, also known as a chute hopper, which is mainly used for hopper elevators where the hopper is continuously arranged. When these hoppers are wound on the upper sprocket, the front wall of the hoisting hopper and the two protruding side walls form a guide channel, which serves as a guide for the material flow discharged from the rear hopper.
