<p>Disclosed is a grinding system (10) with high wear resistance, comprising: a grinding roller (11) and a grinding disc (12) cooperating therewith, wherein the grinding roller and the grinding disc together form a material space (13) having a stable holding force for materials. By means of providing the material space (13) having a stable holding force for materials between the grinding roller (11) and the grinding disc (12), too-fast wear between the grinding roller and the grinding disc can be efficiently avoided. In addition, the material space can increase an angle of attack (a) of the grinding roller, increase material raking strength, increase a friction force, improve the wear resistance of the grinding roller and the grinding disc and improve the total productivity of a vertical mill.</p> |
