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.
