There are various reasons for bucket elevator powder leakage, for example, the wrong feeding method since the elevating machine self problem, or the large height differences of buckets feeding increases the feeding pressure. Also, it might because of no full welding and gap existence with the connection joint. The bad sealing gasket at casing flange place causing the machine problem, in the process of hoisting, materials falling down from the crack in the head and engine base of bucket elevator conveyor, produces ash leakage phenomenon.
The treatment for bucket elevating conveyor is to reduce the height difference of feeding to reduce feed pressure, or add material buffer device at the bucket to ensure the stable transmission and improve the hoisting efficiency. In the practice operation, if the powder leakage has already appeared, the glass glue could be applied at the weld joint.
