Friction roller aligning roller group for belt conveyor

The assembling of carrier roller adopts technology of assembling before welding and is conducted on double-end welding machine. The welding of bearing pedestal and pipe is conducted at the same time. CO2 gas automatic protection welding is adopted. Ours is the most advanced production line for carrier roller at home currently.

Roller Major technical parameters:

Roller resistance to rotation (Non-contact seal)

The amount of radial run-out

 Roller Axial load

Roller'S Axial float

Under the impact of axial load of 500N, the axial float figure≤1.2mm

Roller Dropping intensity

After experiments of horizontal and vertical drop of carrier roller, the following requirements should be met:

1. All components and welded joints cannot be damaged or taken apart;
2. Axial displacement of roller carrier after falling should be not more than 1.2mm;
3. The body and bearing of carrier roller should never be loosing;
4. The resistance to rotation should be not more than 1.5 times of the figure stipulated in table 1.

Roller Sealability in water

After revolving at the rate of 1450t/min for 24 hours in water, the water inflow of the carrier roller with non-contact seal device is not more than 150g.

Roller Life span

When reinforced service life of carrier roller is converted into the actual service life, the time span is no less than 20000h. The damage rate of carrier roller is no larger than 10%.

Roller Range of application

Our product is widely used in such surrounding as underground coal mine and that with severe open-air dust and high corrosivity. These places include mines, power plants, steel mills, stone factory, cement plant, coking plant, coal washing plant, saltworks, soda ash factory, chemical fertilizer plant and wharfs.
