Flame-retardant compounds used in the manufacture of conveyor belts, such as antimony oxide, enhance the ability of conveyor belts

Underground safety of conveyor belts

Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining

Conveyor Belt Fires Create A Safety Hazard In Industry

Nov 02, 2018  The most common type of conveyor is a belt conveyor, which uses a single long roll of fabric or rubber rotated around a path using gears and motors to pull the belt and the load on it. However, this movement of the belt creates large amounts of friction, which causes severe issues with conveyor belt fires when conveying flammable materials.
