The conveyor belt carries material between the head pulley and tail pulley. The conveyor belt is composed of two layers of material; the under layer and the over layer. The under layer provides linear strength and shape, it is composed of woven fabrics that have warp and weft such as polyester, nylon or cotton. The over layer, often referred to as the 'cover', is composed of a material such as rubber or

Underground Coal Mine Transportation System - SKE

In the underground seams, we use shearer to crush coal from the walls, and the crushed coal will often be sent to the scraper conveyor. The scraper conveyor will feed coal onto a belt conveyor. We can use belt conveyor as underground coal mine transportation machine. It can help us move coal to the surface where we will store them. This is The Underground Coal Mine Transportation Principle.

Belt Conveyor Fatal Nip Hazards - SPC/Tech/SI1/11

A diagram showing these locations on a conveyor belt are shown at Annex 1, and Annex 2. Note: A similar point on the out-running side of the drum or roller where the conveyor belt exits is not the dangerous location, unless the conveyor can be reversed. This is important because in some cases it is difficult to identify the nip point side, for example, in some conveyor loop take-up systems.
