representation of the general conveyor belt coal mine PVC and PVG whole 

core resistance burning with intensity level and conveyor belt width to 

represent. Intensity level is generally divided into: 4, 5, 6, 7, 8, 9, 10, 

11 and up to 16 bands respectively corresponding to intensity: 680S, 800S, 

1000S, 1250S, 1400S, 1600S, 1800S, 2000S, 2240S, 2500s, 2800S, 3100S and 

3400S. Conveyor belt width is generally: 500mm, 650mm, 800mm, 1000mm, 

1200mm, 1400mm, 1600mm, 1800mm and so on. China provides that all coal mine 

conveyor belt products used must comply with the relevant standards of 

fire-retardant anti-static conveyor belt. Now commonly used in coal mining 

enterprises conveyor belt: PVC whole flame retardant anti-static conveyor 

belt, PVG whole flame retardant anti-static conveyor belt, steel cord 

conveyor belt fire-retardant anti-static. Retardant anti-static conveyor 

main provisions of the safety performance of the product: 1, alcohol burner 

combustion; 2, surface resistance; 3, roller friction; 4, analog gateway 

propane combustion. These test items characterize the safety performance of 

the product. Steep Ribs conveyor belt with corrugated wall large angle from 

the base band, ribs, transverse bulkhead 3 parts. To prevent the material 

from sliding wall measuring scattered role. For ease of bypassing the drum, 

corrugated edge design file; diaphragm is the role of cross-bearing 

material care, in order to achieve a large transmission angle, using T-TC 

type. Profile edges and transverse bulkhead is a secondary curing method 

connected with the baseband with very high bonding strength.
