Products
1 - carrying side rubber cover;
2 - fabric insert ply (carcass);
3 - rubber gasket;
4- back rubber cover.
The type 2 belts are made of rubber carcass, carrying and back rubber covers with rubber capped edges.
The type 3 belts are made of rubber carcass and carrying rubber cover with cut edges.
The type 4 belts are made of rubber-fabric carcass and rubber carrying and back covers with cut edges.
Conveyor belts have a strict marking every 10-20 m along the belt.
The marking includes:
- trademark of the enterprise;
- belt type and sort;
- cloth type;
- width and amount of side irons;
- thickness of rubber linings and class of rubber;
- number of a belt;
- part due date.
Rubber-fabric conveyor belts type 2T1, 2T2, 2T3 are oriented on the transportation of hot material cargos with the temperature of 100°С, 150°С and 200°С at the enterprises of ferrous and nonferrous metallurgy, chemical industry etc.
