When the traditional high-pressure roller mill roller system works, the abrasion is uneven, the extrusion stress of the roller edge to materials is reduced, the materials run thick at the roller edge, in order to improve the crushing and grinding efficiency, the baffles are added at the two sides of the roller sleeve, and a relatively airtight space is formed. The fixed roller system and the floating roller system of the high-pressure roller mill rotate in opposite directions and are crushed and ground under the action of the force between the material layer and the baffles on the two sides, so that the abrasion loss of the roller edge is very large, and the roller edge is difficult to repair after abrasion. Therefore, it is necessary to provide a reinforcing roll edge at the edge of the roll shell to reduce the amount of wear.
