In order to ensure the reliable operation of belt conveyor, the main thing is to find and eliminate possible faults in time. For this reason, the operator should observe the working condition of the transporter at any time, and deal with the abnormality in time if it is found. It is important that mechanical workers regularly inspect and inspect any situations or components that need attention. For example, a supporting roller is not very important, but the high-speed conveyor belt conveying abrasive materials may quickly wear through its shell and produce a knife edge, which may seriously damage an expensive conveyor belt. Trained workers or experienced workers are able to detect and prevent impending accidents in a timely manner. The conveyor belt of belt conveyor accounts for a considerable proportion of the whole conveyor cost. In order to reduce the cost of replacing and repairing conveyor belts, attention should be paid to training operators and maintenance personnel on the operation and maintenance of conveyor belts.
