Keeping track of conveyor systems

1. Material builds up on conveyor belt and rollers. This is usually caused by spillage at transfer points and/or an ineffective belt cleaning system. 2. The loading of the belt is not centralised.

Manual vs. Automatic Sampling: Why Aggregate Producers…

The tip speed of the cutter is used for comparison purposes with belt speed, but in general, the cutter speed should always be faster than the belt speed. How much faster usually varies by application, but a minimum value is often expressed as a cutter velocity that is at least 1.5 times the conveyor belt velocity.
