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.
