STEEL CORD BELTS

Belt cross-section



1) Steel cord belts are used in the following cases:
  • severe operating conditions;
  • high output;
  • long installations and steep inclination;
  • high resistance of the belt to breaking.
Main advantages:
  • possibility to use belts with high resistance to breaking (ST 7000 N/m);
  • low elongation, making it possible to use the long conveyors with reduced tensioning path;
  • operation safety and long service life;
  • good lateral flexibility allows the use of large angles of the trough;
  • small diameter idlers can be used;
  • durability and service life of the splices similar to the operating period of the belt.

Belt structure



Belt structure:
Shields: excellent resistance to abrasion, aging and UV rays.
Adhesive rubber: Adhesion to galvanized wires and shields: excellent penetration of rubber, high shear rate, resistance to aging.
Transverse reinforcement: depending on the application – with or without transverse fabric or metal breaker/weft.

Availability:
  • width from 600 mm to 2000 mm;
  • durability from 500 N/mm to 4000 N/mm;
  • type series 4+3, 6+3.

2) Steel cord belts with metal transverse reinforcements (2 wefts)

Belt cross-section



Belt structure:
These belts are manufactured with two types of the core (carcass wires and weft wires): The core with elastic wires of the M type carcass (4x7 structure), resistant to strong impacts, particularly suitable for:
  • conveyors with small diameter idlers;
  • curved routes of the conveyors with small radii;
  • severe operating conditions;
  • frequent stops and starts.
The belt has its own core with three layers of steel wires (wires with variable elasticity). This type of structure has various advantages. These advantages include:
  • excellent wire/rubber adhesion;
  • resistance to repeated impacts;
  • resistance to penetration of moisture into the wires;
  • ability to discard foreign matter;
  • reduction of longitudinal cuts and tears;
  • possibility to completely use up the shields;
  • ability to wind onto small diameter idlers;
  • ability to take small diameter crests;
  • durable splices;
  • easy repairs in emergency situations.
Main advantages:
  • long service life of the belt;
  • cost-effective maintenance;
  • improved stability;
  • safe usage;
  • quick repairs;
  • improved production performance.
Availability:
  • width from 600 mm to 2000 mm;
  • durability from 500 N/mm to 4000 N/mm;
  • type series 4+3, 6+3.

3) Steel cord belts with metal transverse reinforcements (1 weft)

Belt cross-section



Belt structure:
The belt consists of a combination of two layers of wires embedded in rubber. The core contains:
  • one layer of ropes running toward the carcass;
  • one layer of ropes running toward the weft.
The belt is designed from individually and equally tensioned wires. A layer of rubber separates each layer of the wires, carcass and weft to avoid the risk of the material’s fatigue corrosion.

Main advantages:
  • long service life of the belt;
  • cost-effective maintenance;
  • improved stability;
  • safe usage;
  • quick repairs;
  • improved production performance.
Availability:
  • width from 600 mm to 2000 mm;
  • durability from 500 N/mm to 4000 N/mm;
  • type series 4+3, 6+3.
