Reasons and solution of belt slippage on belt conveyors

The conveyor belt slippage of the belt conveyor means that the tape and the drive roller slip. Slippage of the conveyor belt is a kind of production failure often encountered in production. The belt slipping may cause the belt to wear, and in serious cases, the conveyor belt may be burned or even cause a fire.

To overcome the slippage phenomenon of the conveyor belt, we must first find the cause of the slippage, so as to take effective measures, because the transmission of the belt mainly depends on the friction between itself and the drum. The reason why the slip is because the friction is too small, and the friction is to be improved. . The following points explain the belt conveyor slippage solution
Belt conveyor belt slip solution:

1. Solve the slip of the belt of the heavy hammer tension belt conveyor. The belt conveyor using the weight tensioner can be added when the belt conveyor belt slips, and added to the belt without slipping. However, it should not be added too much to avoid the belt conveyor's belt from being subjected to unnecessary excessive tension and reducing its service life.

2. Solve the slippage of the screw tensioning or hydraulic tensioning belt conveyor belt. With a belt tensioner or a hydraulically tensioned belt conveyor, the tensioning stroke can be adjusted to increase the tension when the belt is slipping. However, sometimes the tensioning stroke is not enough, causing the belt conveyor belt to be permanently deformed, and the belt can be cut off for a while to re-vulcanize.

3. When using nylon belt or EP, it is required to have a long tension stroke. When the stroke is not enough, it can be re-vulcanized or the tensioning stroke can be increased to solve the belt conveyor slip problem.

4. The initial tension of the conveyor belt is too small. The tension of the conveyor belt leaving the drum is insufficient to cause the conveyor belt to slip; this situation generally occurs at the time of starting, and the solution is to adjust the tensioning device to increase the initial tension;

5, the tail roller bearing damage does not rotate or the upper and lower roller bearing damage does not turn too much; the cause of the damage is that the tail is too heavy, there is no timely repair and replacement of damaged or inflexible parts, so that the resistance increases Slip

6, the friction between the drive roller and the conveyor belt is not enough to cause slipping; or because there is water on the conveyor belt or the environment is humid; the solution is to add some rosin to the drum; but be careful not to add by hand, and the application Blowing equipment is blown in to avoid personal accidents;

7. If the starting speed is too fast, it can form a slip; at this time, it can start slowly; if the squirrel cage motor is used, it can be started after two times of jogging, which can effectively overcome the slip phenomenon;

8. The load on the conveyor belt is too large, and the motor capacity will slip even more. At this time, the slipping side is beneficial to protect the motor; otherwise, the motor will be burned after a long time; but it is a slipping accident for the operation.
