How to deal with the slip of bucket elevator?

Article source: admin release date: July 13, 2020

We're using it Bucket elevator More or less, there will be some problems, such as slipping. What are the reasons and how to solve them? Let's have a look.

1. The inner surface of head wheel drive shaft and hopper belt is too smooth

The internal surface of the head wheel drive shaft and hopper belt is too smooth, which reduces the friction between them and causes the hopper belt to slip.

Solution: a layer of glue can be applied on the inner surface of drive shaft and hopper belt to increase friction.

2. The tension of hopper belt is not enough

The bucket elevator uses the friction torque between the hopper belt and the head wheel drive shaft to lift materials. If the hopper belt tension is not enough, the hopper belt will slide.

Solution: stop the machine immediately and adjust the tensioning device to tighten the hopper belt. If the tensioning device can not make the hopper belt fully tensioned, it means that the travel of the tensioning device is too short and should be readjusted. The correct solution is to untie the hopper belt joint, adjust the tensioning device on the bottom wheel to the position, put the hopper belt into the head of the elevator, pass through the head wheel and bottom wheel, and connect the head and tail, so that the hopper belt is in the state of tension but not tension. Then fully tension the tensioning device. At this time, the unused tension stroke of the adjusting screw of the tensioning device should not be less than 50% of the full stroke.

3. The bearing of head wheel and bottom wheel does not rotate properly

In this case, the resistance moment will increase and the hopper belt will slip.
Solution: it can be disassembled, cleaned, oiled or replaced with bearings.

4. Hoist overload

If the bucket elevator lifts too much material, the resistance torque will increase and the hopper belt will slip.
Solution: at this time, the feeding amount should be reduced and the feeding uniformity should be ensured. If the slip still can not be improved after reducing the feeding amount, it may be that there are too many materials accumulated in the machine seat or the hopper is stuck by materials, so the machine should be shut down for inspection and troubleshooting.
