Belt Conveying System Coal Mine Roller Idler Conveyor Roller Conveyor

Belt Conveying System Coal Mine Roller IdlersConveyor belt rollers are one of the important parts in belt conveyor. It accounts for 35% of the total cost of a conveyor belt and has suffered more than 70% of the resistance ,so the quality of the roller is particularly important.
The scope of conveyor roller has food, cement, electric power, mining, chemical industry, building materials, steel, conveyor equipment, coal, metallurgy, etc.
Through the friction between belt and roller, roller conveyor drives the roller tube body, rotation of the bearing and the bearing outer ring, sealing ring and the conveyor belt to realize the transmission of logistics.
Conveyor rollers mounted on the belt transport planes is used to support the belt. The belt suspension shall not exceed the technical requirements so that can ensure the belt running smoothly.FeaturesThree sealing device, dustproof and waterproof.Good strengthSmall amount of radial runoutLight weight, low energy consumptionLong service life (more than 50000 hours)Small radial runout, which of carrying idler is below 0.35 mm.
Application
The Carrying roller is usually equipped in the belt conveyor, which is widely used in coal mines, metallurgy, ports, construction site, power station, and chemical, food industries.
