How to deal with too much return material of th bucket elevator?

Article source: admin release date: August 18, 2020

How to solve the problem of excessive return of th bucket elevator?

Th type bucket elevator returns too much, which is caused by not considering the characteristics of materials in the design process, choosing the depth of hopper, speed of rotation, etc. Th type bucket elevator return material and we usually say the concept of return material is not the same. Return material of th bucket elevator refers to the phenomenon that the material is not completely discharged from the machine at the unloading position, but some materials return to the elevator frame. In the lifting operation, if the th bucket elevator returns too much, it is bound to reduce production efficiency, increase power consumption and material crushing rate. There are several reasons for the excessive return of materials

1. The discharge tongue at the head outlet is not properly installed, and the tongue plate is too far away from the discharge position of the hopper, which will cause material return. The position of tongue plate should be adjusted timely to avoid material return.

2. If the hopper runs too fast, the speed of the hopper is different when the elevator lifts different materials

Generally, the speed of lifting dry powder and granular material is about 1 ~ 2m / s;

The speed is 0.4 ~ 0.6m/s for bulk materials and 0.6 ~ 0.8m/s for wet powder and granular materials.

If the speed is too high, the unloading is ahead of time, resulting in material return. At this time, according to the material to be lifted, the hopper speed should be appropriately reduced to avoid material return.

The above is the reason and solution of excessive return of th bucket elevator.
