The roller has large rotation resistance, and the frictional resistance between the roller and the conveyor belt is large, causing friction; the rotation direction of the roller and the running direction of the conveyor belt are declination, and the deflection friction resistance is formed to cause the roller to wear; the running environment of the roller itself is bad, resulting in Frictions such as direct contact of the rollers with coal (ore) or other items are common causes of damage to the belt conveyor idlers.
Regarding the analysis of the reasons for the damage of the belt conveyor roller, if you have any questions, please feel free to contact our Xinjian tape professionals. Xinjian Tape is dedicated to serving every customer!
Next, Xiaojian tape's small series brings everyone to learn about the types of rollers commonly used in belt conveyors.
Category 1: Transition Roller
Large-capacity, long-distance, high belt tension and important conveyors should generally be provided with transition sections.
Type 2: Groove type idler
The standard groove angle of the upper roller is 35 degrees, so the most used in each conveyor is the 35 degree groove roller and the 35 degree groove forward roller.
Category 3: Buffer Roller
Buffer rollers are 35 degrees and 45 degrees. When using canvas conveyor belts, only 35 degree groove cushion rollers can be used. When using a 45 degree grooved cushioning roller, a 45 degree grooved roller can be used in the section where the guide groove is not impacted by the material.
Category 4: Return roller
The return idler is also called the parallel lower roller, which is also the most used lower roller.
Category 5: Self-aligning roller
The centering roller includes a conventional centering roller, a friction centering roller, and a tapered centering roller. The self-aligning roller is used to automatically correct the excessive deviation of the conveyor belt during operation to ensure the normal operation of the conveyor.
