Rubber conveyor belts are mainly used for Gute bulk material transportation. It mainly consists of carcass and cover.
Usually the carcass of rubber conveyor belts is made of fabric and steel cords, which provide reliable strength for the belt. The covering layer determines the application of the belt conveyor.
Although belt conveyors look the same on the outside, they have different characteristics. This is determined by the rubber grade of the cover layer.
Grade A conveyor belts are usually wear-resistant conveyor belts.
When conveying very rough and abrasive materials, the Rayco rubber conveyor belt will wear out too quickly. In addition, special cleaning systems for conveyor belts, such as scrapers, conveyor belt skirts and other accessories can also cause belt wear.
Therefore, when transporting large, hard materials, a conveyor belt made of Class A rubber should be used. Although its price is higher than that of general-purpose rubber, you have to know that the cost of frequent disassembly and installation and replacement of conveyor belts may be higher. Therefore, it may be more cost-effective to choose a rubber conveyor belt with higher wear resistance.
Wear-resistant conveyor belts are widely used in mines, quarries, construction aggregates and other fields to transport crushed stone, sand, minerals and other materials.
The static charge in the conveyor belt may be caused by the friction between the conveyor belt and the slider bed and/or the movement of the conveyed product or the ionization of the air (dry and dusty environment). Although the quiescent current is usually low in intensity, sparks may still be generated.
When there are potentially explosive substances (such as gas, liquid, powder and dust), static sparks must be minimized because the risk of explosion may be fatal.
The anti-static conveyor belt is an E-class conveyor belt, which can conduct static electricity generated during transportation and transportation, and release electric charges-usually into the grounding path.
The common use of E-grade rubber belts is in aluminum refineries. Aluminum usually releases excess electrons, which can cause static electricity to build up. The electrostatic conduction belt is used to absorb excess electrons and discharge them safely.
Fire is one of the main threats to conveyors, and the gas released when the belt burns can cause death.
Therefore, fire-resistant conveyor belts must be used when transporting flammable or overheated materials. Because ordinary rubber conveyor belts do not have fire resistance.
In underground mines, coal mines and power stations, F grade rubber conveyor belts are required. Because once a fire occurs on the underground conveyor belt, the smoke produced is fatal.
Garde M & N
General purpose rubber is the most common type of rubber conveyor belt and is used in industries that do not require special performance conveyor belts. N grade rubber is of lower quality than M grade rubber. M grade rubber has higher hardness, higher wear resistance and higher strength than N grade rubber. Therefore, the only difference between M-grade rubber and N-grade rubber is the quality of the rubber.
This is a mixture of E grade and F grade rubber. The S grade rubber conveyor belt has antistatic and fireproof properties. Mainly used in underground mining.
The Z-grade rubber belt is a conveyor belt specially designed for special purposes. This grade is used when the rubber performance does not meet any other category.
