The bucket elevator is a kind of mechanical equipment used for conveying materials from a lower position to a higher position. This is one of the common mining machinery used in processing industries. It is able to convey large materials size and particles such as coal, cement, sand and rocks. If the Bucket Elevator malfunctions, the source of faulty operation may frequently be found by observing the nature of the fault and applying some simple checks and remedies to correct the malfunction. The following troubleshooting table is provided for this purpose.
| Trouble | Possible Causes | Remedy |
| Normal capacity cannot be attained | 1.Material is bridging at inlet. 2.Motor not developing operational RPM. 3.Material caked on buckets. | 1.Correct method of feeding to insure even feed at elevator’s rated capacity. 2.Correct power source problem. 3.Clean buckets. |
| Unit stalls or plugs up | 1.Belt has too much slack causing buckets to jam. 2.Motor not developing operational RPM. 3.Discharge spout or down spouting plugged. 4.Slipping drive. | 1.Make adjustment at take up bolts. 2.Correct power source problem. 3.Check all spouting for foreign material, build-up, dents and turns which may impede material flow. 4.Adjust drive belts and roller chain tension. |
| Noisy operation (i.e. buckets rattling) | 1.Elevator out of plumb. 2.Belt too loose or not centered on pulleys. 3.Material caked on pulleys. 4.Damaged or loose buckets. | 1.Straighten elevator and plumb. Position braces so elevator is not forced out of alignment when attached to structures which may shift with loading or unloading. 2.Take up belt at splice, re-align and tighten belt with take-up bolts. 3.Clean pulleys 4.Replace or tighten buckets. |
| Pulley drags or does not turn | Frozen bearing | Lubricate or replace bearing |
