Abrasion Wear 165mm Conveyor Impact Roller For Coal Mining Industry
Coal Mining Industry Rubber Disc Impact Roller With CE Certificate
The Impact roller is to improve the density of the device in terms of the device; the other is to check frequently and replace the damaged roller in time. Regarding the conveyor belt with large blanking drop, it is recommended to install a Impact air lock device, and replace the Impact roller with a Impact bed. In terms of purchase, the following points are put forward based on the characteristics of the Impact roller: the amount of radial runout of the roller, the sensitivity of the roller, the amount of axial movement, the dustproof function of the roller, the waterproof function, the axial bearing function of the roller, the support Roll anti-impact function, etc.
The Impact roller is applied to the tailstock of the machine according to the actual situation. When receiving the material, it can reduce the impact of the material on the belt, which is beneficial to the service life of the long belt. The trough-shaped roller is generally composed of two side rollers and a flat roller. The groove angle is generally 30 degrees. For a detachable belt conveyor, the three rollers of the trough-shaped roller are hinged to each other, so Called hinged roller. The parallel roller is generally a long roller, which is installed at the lower end under pressure, so it is called the lower roller.
What problems should be paid attention to when assembling 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. When replacing the bearing, the bearing cage needs to be opened outwards. After the bearing is installed into the idler roller, the proper clearance should be maintained and it should not be crushed.
3. It is the sealing performance and use performance of the roller. It is forbidden to disassemble the roller at will.
4. During use, the roller should be prevented from hitting the roller tube by heavy objects.
5. The normal service life of the roller is more than 10000h, and generally does not need maintenance. 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.

The Impact roller has strong abrasion resistance; both ends are equipped with plastic labyrinth seals, oil and grease will not leak, which can make the rolling shaft run for a long time, and the Impact roller can run in a fully sealed state. Impact aprons are basically made of recycled rubber, which not only has poor elasticity, but also has poor abrasion resistance, tear resistance, and aging resistance. Due to the large dust at the blanking point, the buffer roller can easily be contaminated when its sealing performance is poor. The nylon roller can cause damage to the bearing; when the impact force is small, the service life is only about 1 year. When the impact force is large, it will take more than ten days. Fracture and fall off, causing serious damage to the tape. At present, a new labyrinth seal has emerged to ensure that the bearing is not polluted for a long time, and the bearing life reaches more than 100,000 hours. The rubber ring is replaced with automobile tire rubber, which has outstanding comprehensive properties such as abrasion resistance, impact resistance, tear resistance, aging resistance, high elasticity, etc., which increases the service life of the Impact roller by 20 times, and the economic benefit of the buffer bed is 10 times higher. Not only the buffer roller, but also the Impact roller and the buffer roller, there will be damage.
