The roller is an important part of the belt conveyor. There are many types and large quantities. The function is to support the belt, reduce the running resistance of the belt, and make the verticality of the belt not exceed a certain limit to ensure the smooth running of the belt.
idlers are classified into self-aligning idlers, buffer idlers, trough idlers, and parallel idlers according to their uses. The function of the self-aligning roller is to correct the deviation of the belt conveyor. Usually, a rotary groove-shaped self-aligning roller is installed on the heavy-duty section of the conveyor, and a parallel self-aligning roller is installed on the no-load section. The buffer 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.
Feature of belt conveyer rollers
1) strong construction
2) Better balance
3) Low T.I.R
4) Accurate bearing alignment
5) Maximum sealing efficiency
6) Low running resistance
7) Long service with more than 30,000 hours
