Multiple drive conveyor systems are already widely used in under-ground coal mines and are increasingly being considered in the mining plan for future developments [32]. Fig. 1 illustrates the evolution of the belt tension pro le before and after one, and subsequently, two drive stations are inserted in the upper stretch of a single drive conveyor.

A tensioning device should be designed to be compatible with the cleaner in order to provide a consistent blade-to-belt pressure throughout the life of the blade. When cleaner adjustment and re-tensioning are required, the tensioner should allow this maintenance to be performed simply, without requiring tools or more than one service worker.

Slat conveyors are a type of conveying technology that utilizes a chain-driven loop of slats to move product from one of its ends to another. The chain is driven by a motor, which causes it to cycle just as belt conveyors do. The main difference is that, instead of a rubber belt, this conveyor type uses slats connected to a chain, not ...

As shown in the figure below (Figure A), the tension on the belt is accomplished by turning the screw at the end of a conveyor. This pushes the bearing block towards the end of the conveyor, which adds tension to the belt. There is another, identical jack-screw located on the opposite side of the roller.

The calculation to obtain the tension at a particular node is given in Equation 2. The calculation is started at a point of known tension, such as the gravity take up, then progresses around the conveyor to points on either side of the drive. Most conveyor system designs would require at least this level of analysis.

To conclude, the total belt tension as calculated above is usually expressed as a unit tension for reference against various information tables. This is done by dividing the total calculated tension by the belt width. Therefore Unit Tension = Belt tension (N) / Belt width (mm) giving units of N/mm width.
