Wear Resistant Rubber Coated Belt Tracking Roller 165mm Diameter
Conveyor Belt Impact Roller With Rubber Cover For Bulk Material Handling Equipments
The impact roller is used for the belt conveyor to slow down the impact of the falling material on the conveyor belt. It is a type of roller that is mainly developed for corrosive environments such as coal washing plants, coking plants, and chemical plants. Its inherent toughness is ordinary More than 10 times that of metal, five times the life span of traditional pillar shoes, corrosion-resistant, flame-retardant, anti-static, light weight, etc.
It is widely used in mining. The special polymer material for the roller body has mechanical properties similar to bronze, has good wear resistance, and has good self-lubricating properties, and does not damage the belt.
The impact roller has superior anti-corrosion performance. The roller body and the seal are made of polymer materials, which are corrosion resistant. Used in corrosive occasions, the service life can reach more than 5 times that of ordinary rollers.
How to maintain the sealing performance of the Impact roller?
(1) The labyrinth seals should be made of original parts, and should be put into the rollers during assembly, and should not be assembled together.
(2) For the sealing performance and use performance of the roller, it is forbidden to disassemble the roller at will.
(3) The normal service life of the roller is more than 20000h, and generally does not need to be repaired. However, according to the place of use and the size of the load, the corresponding maintenance date should be established, and the oil injection maintenance should be cleaned in time, and the floating coal should be cleaned in time. The rollers with abnormal noise and non-rotating should be replaced in time.
(4) When replacing the bearing, the opening of the bearing cage needs to be opened outwards. After the bearing is installed into the idler, the proper clearance should be maintained and it should not be crushed.
(5) During the use of the idler, prevent heavy objects from hitting the idler tube.

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.
