Experimental Study on Abrasion Resistance of Grinding Rolls with Stripes Surface

Abstract:

In order to study the impact on the roller abrasion resistance of the surface structure parameters such as stripes depth and number, roller abrasion model experiments were carried out with quartz sand as granular material and optimal design method was used to arrange testing program. Based on structural features of roller press, a model test bed was build and stripes roller were design and manufactured according to similar principles. Roller surface structure parameters were determined by orthogonal polynomial regression design method. By processing the test data, a regression equation was obtained with stripes depth, number and the amount of wear as parameters. The results showed that: Stripes structure grinding rollers have better abrasion resistance than the light roller; The depth and the number of stripes have a greater impact on the abrasion resistance and there was an interaction between them; In the same conditions, when the stripe depth is fixed, the wear amount increases with the number of stripes increasing; when a fixed number of stripes, the wear amount decreases with stripes depth increasing.
