High Quality Conveyor Roller Mining Belt Conveyor Flat Return Idler Roller
1. Conveyor rollers mainly consist of roller shell, bearing and
bearing housing, shaft, and seal. It has the features of long
service life, low noise, greater load carrying ability and fully
sealed.
2. Flat Rollers (Carrying Rollers)
-Flat rollers are used for bulk and unit material handling
applications
3. Impact Rollers
A. Impact rollers consist of a base steel roller design, on which
are fitted rings, designed to resist and absorb the pressures given
by the impact of material onto the the belt.
B. Impact rollers are positioned in the carrying section of the
belt, corresponding to the point of loading where the material
falls onto it.
4. Return Rollers with Spaced Rings (Rubber Disc Rollers)
A. Rollers with spaced rings are used to sustain and support the
belt during its return section, where the conveyed material tends
to stick to the belt or wherever there is a wear problem or
tracking problem of the belt itself.
5. Return Rollers with Helical Rubber Rings (Spiral Rollers)
A. The helical spiral form of the non-abrasive rings, assembled
onto the base roller shell, performs a cleaning action and reduces
the tendency of material to deposit itself and stick to the surface
of the dirty side of the belt.
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)

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.
