     Roller's role is to support the conveyor belt and the weight of the material.Roller must be flexible and reliable operation.Reduce the friction with roller conveyor belt, to take up of the total cost of more than 25% of the conveyor belt conveyor life plays a key role.Although the roller in the belt conveyor is a smaller parts, structure is not complicated, but to create high quality roller is not easy.
Judgment criteria for roller has the following several: roller eccentricity quantity;Roller flexibility;The axial momentum.

Main classify

1, according to the material into rubber roller, ceramic roller, nylon roller roller and insulation.
2, main grooved roller group, all kinds of parallel roller group, all kinds of self-aligning roller group, all kinds of buffer roller group.
(1) grooved rollers have normal roller, forward type roller, quick change bearing roller, hanging roller, three roller chain, reversible roller type, variable groove Angle roller, transitional rollers, v-shaped roller, etc.;
(2) the parallel rollers have normal type roller, brush roller, forward rollers, plastic steel roller, screw type roller, etc.;
(3) the self-aligning roller is universal, friction reversing type roller, strong type roller, taper roller, screw type roller of roller, combination, etc.;
(4) the buffer roller type spring plate roller, buffer roller, strong buffer roller, adjustable elastic roller, hanging roller, etc.;
