With the rapid development of the coal mining industry and the increasingly strict national requirements for safe production,Conveyor beltsAs an important equipment in coal mine production, its selection has become particularly important. The purpose of this article is to help more coal mining manufacturers choose a more suitable one for themselves based on their own production needsConveyor beltsto improve production efficiency and achieve sustainable development.
Due to the harsh working environment of coal mines, containing gas, and the coal itself is flammable, the first thing in the selection of conveyor belts is to ensure that underground coal can be transported safely and stably. Our country is also aimed atCoal mine conveyor beltsA series of regulations have been promulgated that conveyor belts used underground must obtain safety marks and production licensesFlame retardant conveyor belts
At present, the coal mine is the mainstreamFlame retardant conveyor beltsThere are two kinds, one isFabric core flame retardant conveyor belt(Implementation of MT 914-2008 standard), the second isFlame retardant conveyor belt with wire rope core(Implements MT T 668-2019).
Fabric core flame retardant conveyor beltIt has good flame retardant performance, which can effectively avoid fire accidents and ensure production safety. It is generally made of high-strength fabric materials and flame retardant rubber, which has the characteristics of good flame retardant, antistatic, waterproof, moisture-proof, tear-resistant, thin belt, small weight, low energy consumption, etc., and is suitable for material transportation in coal mining, chemical industry, electric power, metallurgy, building materials and other industries.
Flame retardant conveyor belt with wire rope coreIt also has good flame retardant performance, when encountering open flames or high temperature environments, the conveyor belt is not easy to burn, will not produce toxic smoke and harmful gases, and effectively avoid the spread of fire and personnel. In addition, the wire rope core flame retardant conveyor belt also has the characteristics of good antistatic, high tensile strength, impact resistance, small elongation, good groove formation, good flexibility resistance, long service life, etc., which can meet different working environments and use needs.
Different from underground coal mines, the requirements for conveyor belts in surface and open-pit coal mines are no longer flame retardant and antistatic, but mainly based on physical and mechanical properties and safety properties, which are preferredLayered conveyor beltswithWire rope core conveyor belt
Layered conveyor beltsIt is made of multi-layer hanging rubber canvas bonded together and covered with rubber by vulcanization and combined, which has the characteristics of large bearing capacity, long service life, strong adaptability and convenient maintenance, and is suitable for ports, docks, airports, warehouses and other industries, and is used to convey block, granular, powdery, pasty materials or finished items.
Wire rope core conveyor beltIt is a conveyor belt made of core rubber, wire rope, covering layer and edge rubber, which has the characteristics of high tensile strength, good impact resistance, long life, small elongation, good groove formation, good flexibility resistance, etc., and is widely used in coal, mining, port, metallurgy, electric power, chemical industry and other fields to convey materials.
