The roller type abrasion tester is mainly composed of a power system, a rotating roller, a sample holder, an automatic shutdown system and a rack and pinion gear device for sample rotation, a base and a dust collector, etc. Product Description: The roller type abrasion tester is mainly composed of a power system, a rotating roller, a sample holder, an automatic shutdown system and a rack and pinion gear for sample rotation, a base and a dust collector. The main principle of the roller abrasion tester is: under a certain load, on a de facto grade emery cloth, the cylindrical sample is cross-cut and ground on the surface of the emery cloth for a certain stroke, by measuring the mass abrasion of the sample, and then The volume wear was calculated from the density of the sample. In order to make the test comparable, a standard rubber must be used at the end, and the test result is expressed as the relative volumetric wear based on the calibrated grinding wheel or as the wear-resistant base number relative to the wear of a certain standard rubber.
