200kg Rubber Coated Conveyor Impact Roller Conveyor Transmission
Transmission Part Conveyor Roller Rubber Coated Impact Roller
Impact roller, a kind of rubber-coated conveyor roller, mainly consists of steel axis, impact disc coated by natural rubber and support rings. Rubber disc is manufactured by black rubber which has excellence elasticity, weather and wears resistance. Conveyor impact roller is designed for carrying loads and reduces damage and breakdown of the material to be transported. It is often be used in mines,metallurgy, power, machinery, construction and other related industries.
There are two types of rollers: steel and plastic rollers. There are three types of bearing seats for rollers: cast iron, stamped steel plate and phenolic plastic.
The seal of the roller can be divided into steel and plastic. Their seals are filled with grease inside. The quality of the roller directly affects the power consumption of the belt conveyor and the life of the belt. Therefore, dust-proof sealing and good lubrication are important standards for use.
The rollers account for 35% of the total cost of a belt conveyor and generate more than 70% resistance, so the quality of the rollers is particularly important.
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:
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 rollers include ordinary rollers, forward tilt rollers,
quick-change bearing rollers, hanging rollers, triple chain
rollers, reversible rollers, variable groove angle rollers, and
transitional rollers. Roller, V-shaped roller, 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.
