Features

With high tensile strength, elongation, good troughability, QuRao resistance and long service life etc.

Use

Suitable for long-distance, high speed, heavy load transportation of materials has been widely used in coal mines, power plants and other industries.

Products

According to the structure points: ordinary and impact resistance, the anti-peel type

Explain

1,execute steel cord fire resistant conveyor belting for coalmine MT668-2008 industry standard

2,company produces rope belt with width:800mm~2400mm

3,Tear-type steel cord conveyor belt is the superstructure of steel cord conveyor belt between the gum and gum-core(or under the plastic cover and the core glue between)plus a layer of tear-resistant net, in order to prevent foreign body into the belt body, tear strength at 50~80N/mm,optional add tear-resistant fabric network, tear strength at 125~800N/mm, optional add tear-resistant steel mesh. Select which tear resistance net more appropriate, Can and of company’s technical staff discussion.

4,users should use company approved sulfide cable connector

5,cable can be based on user needs company provide wire rope on-line detection of core belt(real-time monitoring instrument, it can) in the core wire rope conveyor belt, all ends, twitched the rust, steel wire and adhesive force of such defects drop on-line detection and real-time monitoring.

6,if a user provide conveyor technology parameter, company is willing to help the mining is specified by users of conveyor belt type and recommend acceptable safety coefficient.
