would be 85 kN. However, if the take-up is installed at the tail end, then the counterweight could be reduced to 55 kN. This is due to the fact that the return side belt tensions are increasing from the tail to head conveyor. Therefore the 55 kN tail tension would result in the same 85 kN T2 tension.Web

The material is discharged at the end of the conveyor, or at any point along the length of the conveyor if a belt tripper or plow is employed. Belt conveyors can convey material at angles up to 18°, or 30° with cleated belting; beyond this, a steep incline or pocket conveyor, which allows material to be conveyed anywhere from 30°-90 ...Web

Conveyor belts are designed to carry material with little amounts of trampling from the tail to the head end. When v(t) = v is constant, material flows along the conveyor belt like a constant speed wave (vanDelft 2010). Thus, according to Strauss, the one-dimensional transport equation in describes the flow of material on the belt.Web

In belt conveyor application, a pulley's purpose is primarily three-fold, 1) support the belt in directional changes, as designed in the conveyor, 2) transmit driving power to the belt, and 3) guide or train the belt.
