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
Flame retardant steel cord conveyor belt
(hereinafter referred to as "flame retardant steel cord belt") is composed of a certain number of special steel cord according to the left and right equal distance alternate arrangement, covered with flame retardant intermediate rubber.
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
Prevalent elasticity
Fire safe completion
Impervious to high warmth and wear
Capacity to convey unrivaled execution under outrageous temperatures
High scraped area opposition
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.
