152mm 165mm Dia Black Flat Return Idler For Conveyor Machine
Iron Return Disc Conveyor Roller Idlers For Belt Conveyor
The main characteristics of Iron Disc Return roller are: the
surface of the roller body is equipped with an elastic cleaning
ring-shaped rubber ring, which is used to clean the viscous
material on the carrying surface of the conveyor belt. The cIron
Disc Return roller automatically cleans the bonded materials on the
return belt to remove Fine or powdery materials adhering to the
belt surface to prevent belt deviation caused by it.
Iron Disc Return roller is suitable for conveyors in the industry.
Iron Disc Return roller can replace the previous metal rollers and
nylon plastic rollers. It has long service life, convenient
installation, stable self-defined conveying, reducing conveyor belt
deviation and protecting conveyor belts. Iron Disc Return roller
has better performance than traditional iron rollers, with low wear
coefficient, small specific gravity, light weight, easy
replacement, low noise, stable operation, suitable for working
environments with harsh production conditions, and long service
life.
Different type of conveyor idler:
1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit
material.
2. Impact Rollers: Installed at the loading point to absorb the
shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its
return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt
deviation, preventing hunting and ensuring stable operation of
conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers

Main classification of rollers:
There are several standards for the quality of the Iron Return Disc
Conveyor Roller : the radial runout of the roller; the flexibility
of the roller; the amount of axial movement.
1. According to the material, it is divided into rubber roller,
ceramic roller, nylon roller and insulating roller.
2. There are mainly trough roller groups, various parallel roller
groups, various self-aligning roller groups, and various buffer
roller groups.
(1) Trough idlers include ordinary idlers, forward inclined idlers,
quick-change bearing idlers, hanging idlers, triple chain idlers,
reversible idlers, variable groove angle idlers, and transitional
idlers. Idler, V-shaped Idler, etc.;
(2) Parallel idlers include ordinary idlers, comb idlers, forward
inclined idlers, steel rubber idlers, spiral idlers, etc.;
(3) Self-aligning rollers include universal rollers, friction
reversible rollers, powerful rollers, cone rollers, spiral rollers,
combined rollers, etc.;
(4) Buffer rollers include spring plate rollers, buffer ring
rollers, powerful buffer rollers, adjustable elastic rollers,
hanging rollers, etc.
