Product Details

Steel reinforced rubber conveyor belt

It can be extensively used in the coal, mining, port, metallurgical, electrical and chemical industries, and is applicable for the conveyance of materials with heavy load, long distance and large freight volume.

The core rubber has enough diffusion space for each wire in strand, the bonding strength of the rubber and steel cable is very high, it is rust and corrosion resistance, it relieves the mutual shearing and torsion of the wires in strands, it has high dynamic fatigue resistance, and the product has a long service life .

Tear Resistant(Transverse Reinforced)St Belt
Structure
It uses the new type steel cable as the tension element. On one side or two sides vertical that is perpendicular to the lengthways steel cable, evenly lay the reinforcing layer of the steel cable, steel cord, fabric, etc. broadways.
Character:It has excellent impact and tearing resistance performance.

Character
1.Control: it gives out an alarm and stops running automatically whenever a tearing rupture of the belt is detected.
2.Alarm and stops running automatically whenever the belt runs abnormally and reaches the preset off speed.
3.It has memory function and displays the belt running data and status.

Main technical parameters of the steel cord flame-retardant conveyor belt produced for coal mines in accordance with MT668-2008
