The role of the idler is to support the conveyor belt and the
weight of the material. The work of the roller must be sensitive
and reliable. Reducing the friction between the conveyor belt and
the idler roller plays a key role in the life of the conveyor belt,
which accounts for more than 25% of the total cost of the conveyor.
Although the roller is a small part in the belt conveyor and the
structure is not complicated, it is not easy to make a high-quality
roller.
There are several standards for judging the quality of the idler:
the amount of radial runout of the idler; the sensitivity of the
idler; the amount of axial movement.
Utilization and operation of rollers:
1. Before using the roller, check the appearance carefully for any
serious bumps and damage. The rotating roller should be sensitive
and free from jamming.
2. The installation distance of the rollers should be determined by
scientific calculations based on the type of logistics and the
characteristic transportation volume of the conveyor, so as to
avoid excessive or dense installation.
3. The roller installation should be used to avoid rubbing against
each other.
Characteristics for Transport Roller
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

The role of the roller is to reduce the friction between the
conveyor belt and the roller, which accounts for more than 25% of
the total cost of the conveyor and plays a key role in the life of
the conveyor belt. Although the roller is a small part in the belt
conveyor, the structure is not complicated, but it is not easy to
make a good quality roller. The trough roller set is an important
part of the belt conveyor, with many types and large quantities. It
accounts for 35% of the total cost of a belt conveyor and bears
more than 70% of the resistance. Therefore, the quality of the
roller is particularly important. The radial runout of the roller
affects the belt conveyor. Within the range of runout specified in
our country, the belt conveyor can be kept running smoothly,
otherwise it will cause the belt conveyor belt to resonate and
jump, causing material toss and polluting the environment. The
higher the belt speed, the more it appears that the radial runout
is small.
The role of the idler is to support the weight of the conveyor belt
and the material. After the type and model of the tapered idler and
friction idler are determined, the combined structure design of the
rolling tapered idler and friction idler is required to be
accurate. The normal operation of the tapered roller and friction
roller. The combined structure design of tapered roller and
friction roller includes
1. Lubrication and sealing of tapered rollers and friction rollers
2. Coordination of tapered roller, friction roller and related
parts;
3. Shafting support end structure
4. Improve the rigidity of the tapered roller and friction roller
system.
