The role of the roller is to support the weight of the conveyor
belt and the material. The operation of the roller must be flexible
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, the
structure is not complicated, but it is not easy to make a
high-quality roller
During the use of the roller, the roller bracket should be adjusted
appropriately. If the tape always deviates to one side when no
load, the roller bracket on the deviated side should be moved
forward by 1-2cm in the running direction of the tape, or another
One side of the roller support (or frame) is properly heightened.
This can effectively prevent tape deviation. This will not cause
material leakage, abnormal wear and damage of the equipment, reduce
productivity, and will affect the normal operation of the entire
equipment.
