Spraying Paint 200kg Conveyor Return Roller For Conveyor Belt
Rubber Disc Comb Return Roller for Conveyor Transport System
The Rubber Disc Return roller is covered with a hard rubber ring, and the Rubber Disc Return roller can prevent the conveyor belt from deviating. Rubber Disc Return rollers are used on conveyors that convey viscous materials.
Rubber Disc Return roller is also called comb type cleaning roller. Rubber Disc Return rollers are used on conveyors that convey viscous materials. The surface of the roller body is equipped with an elastic cleaning ring-shaped rubber ring at intervals to clean the viscous material on the carrying surface of the conveyor belt. The comb-shaped roller automatically cleans the bonded materials on the return belt to remove the fine particles or particles adhering to the belt surface. Powdery raw material to prevent belt deviation caused by it. Rubber Disc Return rollers are widely used in mining, power plants, chemical industries and other industries.
Factors affecting the quality of comb idlers:
1. Roller radial runout (this index directly affects the stability
of material conveying)
2. Axial string momentum (directly affects the service life of the
roller)
3. Flexibility (affecting the service life of the roller and the
service life of the tape, as well as the driving power of the whole
machine)
4. Performance (affecting the service life of rollers)
5. Dustproof performance (affecting the service life of rollers)
6. Axial bearing capacity (affecting the service life of rollers)
7. Impact resistance (affecting the service life of rollers)
8. Rotation resistance (affects the service life of the tape)
There are five other criteria for judging the quality of rollers:
1. Dustproof performance of roller;
2. Waterproof performance of roller;
3. Axial bearing capacity of the roller;
4. The impact resistance of the roller;
5. The service life of the roller.

The basic types of rollers:
(1) The rollers are classified into self-aligning rollers, buffer
rollers, trough rollers, and parallel rollers according to their
uses. The function of the self-aligning roller is to correct the
deviation of the belt 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.
(2) The rollers are divided into two types: steel rollers and
plastic rollers. There are three types of bearing seats for
rollers: cast iron, stamped steel plate and phenolic plastic.
