Impact-Resistant Steel Cord Conveyor Belt
Impact-Resistant Steel Cord Conveyor Belt is also called tear resistant steel conveyor belt or anti tear steel cord conveyor belt. This kind of conveyor belt can be widely applied in the fields of coal, mining, port, metallurgy, power, cement, etc. with High strength, low elongation, good impact resistance, trough-ability, and sound flex resistance. Suitable for conveying materials of large load through long distance at a high speed.
Flame retardant Steel Cord Conveyor Belt
Flame retardant Steel Cord Conveyor Belt with unique formula and design can make the belt continuous work under the extremely terrible environment about the temperature300-800 degrees. It is widely used in special application such as cement plant, foundry, iron ore, steel mills, underground and tunneling.
We have successfully supplied our customers from different countries with good quality steel cord conveyor belts according to the requirements of the customers, under international standards of the German DIN22131, Australia AS133, Japan JISK6369, etc.
