• Conveyor Belt An Overview | Sciencedirect Topics

The difference in tension across the drive drum was generated by friction in the rest of the system e.g., losses in the belt and bearings. When the conveyor was carrying material, the tension at the entry to the drive drum increased significantly in order to balance the downhill pull of the charge.

The difference in belt tension across the drive drum must not exceed the limiting frictional force between the belt and the drive drum, otherwise the conveyor belt will come to a halt. The purpose of the snub drum see Figure 33 was to increase the angle of wrap of the belt around the drive drum, which is an effective way of increasing the

2019108 Belt friction is a term describing the friction forces between a belt and a surface, such as a belt wrapped around a one end of the belt is being pulled only part of this force is transmitted to the other end wrapped about a surface. The friction force increases with the amount of wrap about a surface and makes it so the tension in the belt can be different at both ends of the belt.
