In coal mines, we recommend the following 3 conveyor belt types:
1. Flame Retardant Steel cord conveyor belt .
2. Solid Woven PVC PVG conveyor belt
3. General flame retardant FR conveyor belt
Flame retardant steel cord conveyor belt (hereinafter referred to as "flame retardant steel cord belt") is composed of a certain number of special steel cord according to the left and right equal distance alternate arrangement, covered with flame retardant intermediate rubber. Our company can produce, 400mm to 2200mm width, ST/S630, ST/S800, ST/S1000, ST/S1250, ST/S1600, ST/S2000, ST/S2500, ST/S3150, ST/S4000, ST / 4500, ST / 5000, ST / 5400, ST / 6300, ST / 7000, ST / 7500
