ODM Dustproof 89mm Diameter Belt Conveyor Rollers Trough Shaped
Coal Mining Heavy Duty Conveyor Idler Trough Roller Idler for belt conveyor
Conveyor trough rollers are widely used in open-air dusty and corrosive environments, such as mines, power plants, steel plants, stone plants, cement plants, coal washing plants, salt plants, alkali plants, fertilizer plants, docks, etc. Trough rollers are often used in transportation places.
The influence of the radial runout of the idler on the belt conveyor: within the specified runout range, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, causing material toss, polluting the environment, and speeding up the belt. The higher the value, the more beneficial the radial runout is smaller. The standard amount in my country is 0.7 mm, and the amount specified in the Japanese JIS standard is 0.5 mm.
Features of trough rollers
1. The trough-shaped roller has the characteristics: acid, alkali and salt are not corrosive to it.
2. The groove-shaped roller has strong hardness: strong.
3. Good airtightness: the trough roller is fully sealed, with plastic labyrinth sealing rings at both ends, oil and grease will not leak, which can keep the rolling shaft for a long time; the trough roller is running in a fully sealed state.
4. The ceramic surface of the trough roller: an oxide film is formed, the surface is smooth, does not adhere to the material, and the friction coefficient in contact with the conveyor belt is small, which reduces the driving force of the winding.
5. Long service life of trough rollers: trough rollers are 2-5 times longer than steel rollers, and can reduce belt wear, belts do not run sideways, and extend belt service life.
6. Low operating cost: trough rollers can reduce the overall cost of belt conveyors and reduce maintenance man-hours.

Reasons for the damage of the Impact roller:
1. Due to the large amount of dust at the blanking point, the Impact roller can easily be contaminated and cause damage to the bearing when the sealing performance of the Impact roller is poor.
2. The cushion rubber ring is basically made of recycled rubber, not only has poor elasticity, but also has poor wear resistance, tear resistance, and aging resistance. The impact force is small, and the service life is only about 1 year. When the impact force is large , It will break and fall off within ten days, causing serious damage to the tape. In desperate circumstances, many belt conveyors began to choose expensive impact beds.
