Effect of the Bionic Transverse Stripe on Wear Resistance and Crushing Performance of Cement Grinding Roller

To improve the wear resistance and mineral crushing performance of grinding rollers in cement, mining, other engineering fields, a striped groove morphology was designed on normal roller surface this study. The with different parameters quartz sand were tested purposely device. depth number grooves used as structural grooves, test protocol experimental design method. results showed that better than those smooth for sand. For example, 3# bionic reduced by 53.58% compared average amount roller, effect also improved. regression equation between stripe depth, stripes, constructed basis multiple orthogonal It found influence greater distribution grooves. According to analysis distributed roller’s caused friction state be sliding friction, reduced. Striped might change stress process. Additionally, improved, roller.
