Description

Fire Resistant Belt

Fire Resistant belting solutions conveyed involve transport lines that are fabricated utilizing Nylon body/EP body material and comes completed through unrivaled and all around characterized forms including -Calendaring, Assembling, Vulcanizing and Other involved processes. 

The superior construction finish (like Power, Chemical, Light, Metallurgical & grain processing industries and Used under condition of flammable/explosive environment like above coal mines) provided in these belts make these suitable for conveying materials requiring flame resistant as well as static conductive belts in industry sectors


Qualities: 

A main name in the field of assembling and trading heat proof transport lines 

Arrangements explicitly intended to keep fire from spreading over whole belt 

Belts sponsored by fire retardant properties 

Belts fulfilling different testing guidelines as per ISO like fire test, electrical opposition test, drum grating test 

Belts ideal for forestalling fire dangers in coal mineshafts 

Belts intended to lessen support necessities of transports that are inclined to harms by fire at impact heaters 

Belts discovering appropriateness in regions like mining industry, warm force plants, coal cleaning plants and others 


Standard Features: 

Prevalent elasticity 

Fire safe completion

Impervious to high warmth and wear 

Capacity to convey unrivaled execution under outrageous temperatures 

High scraped area opposition

Applications

DIN22131  Cover Grade K, fire resistant steel cord conveyor belt (flame resistant steel cord conveyor belt) is suitable for general uses, such as coal washing/coal cleaning plants on the ground, thermal power plants, fertilizer plants, mining industry. It should meet requirements of electrical and fire safety properties.
