System of milling

The utility model discloses a system of milling, mill and grinding roller that this system of milling set up including cooperation each other, wherein, the grinding roller includes that base member, cladding flexible layer and the cover on the base member establish the wear -resisting track outside flexible layer, being provided with a plurality of mounting holes on the mill, disposing the connected elastic component of one end in the mounting hole, the other end of elastic component is connected to wear -resisting lug. The utility model provides a system of milling during operation, material not of uniform size can correspondingly extrude flexible layer and elastic component respectively through wear -resisting track and wear -resisting lug for wear -resisting track and wear -resisting lug produce making a concession of corresponding direction, and the wearing and tearing of avoiding wear -resisting track and wear -resisting lug to lead to with the too inflexible contact of material have improved system of milling's life.
