Grinding mechanism of vertical coal roller mill

The invention relates to the technical field of vertical roller mills, in particular to a vertical coal roller mill grinding mechanism which comprises a base, a transmission module is mounted in the middle of the base, a grinding disc is in transmission connection with the top end of the transmission module, and a grinding ring is fixedly connected to the top face of the grinding disc in an embedded mode. Three adjusting assemblies are annularly arranged on the outer side wall of the base at equal angles, and a supporting frame is arranged on the outer side of the top end of the transmission module. According to the three-roller grinding machine disclosed by the invention, through the arrangement of the adjusting assembly, when the driving ring moves upwards, the rocker arm is driven to deflect through the connecting rod, so that the rocker arm drives the supporting seat to deflect, and the pitching angle of the grinding roller assemblies during working is adjusted; therefore, the pitching angles of the three
