Grade M-24 conforming to IS:1891 (Part I) 1988 is suitable to withstand high resistance to cutting, tearing etc. In heavy duty applications for highly abrasive materials like metallic ores, coke, stone, rocks etc.
Grade N-17 conforming to IS:1891 (Part I) 1988 is recommended to carry moderately abrasive materials as coal, fine ores, cement, sand etc. |
(a) Grade HR (T1) conforming to IS:1891 (Part 2) 1988, suitable for carrying hot coarse materials upto 125°C and hot fine materials upto 100°C.
(b) Grade SHR (T2) conforming to IS:1891 (Part 2) 1988, suitable for carrying hot coarse materials upto 150°C and hot fine materials upto 100°C.
(c) Grade SHR 180 provides excellent heat resistance and moderate abrasion resistance characteristics & is recommended upto 180°C for coarse and 150°C for fine material. |
Grade O.R conforming to Is:1891 (Part 3) 1988 is suitable for carrying materials which leave residues of fat and oil. |
Conforms to IS:1891 (Part 4) 1988 and is suitable for conveying tea, coffee, food products & pharmaceuticals. |
Grade FR - Fire resistance belting has been developed to meet Indian and Canadian standards specifications. This grade is specially meant for conveying coal in thermal power stations where fire hazards exist. |
This belt is designed to prevent fire risks in coal mines where is not easily accessible and to reduce maintenance of the conveyors.The important characteristic is self-extinguishable cover rubber and meet drum friction test. It is suitable for serving in mining industry, power plant, electric utilities, coal cleaning plants. |
