Superfine vertical pulverizing machine

The utility model discloses a superfine vertical pulverizing machine which comprises a host machine body (16), a host machine shell (17), an electric motor (7), a speed reducer (6) connected with the electric motor (7), a grinding pan (5) driven to rotate by the speed reducer (6), and a grinding wheel (2) driven to rotate relatively by the grinding pan (5); and the superfine vertical pulverizing machine is characterized in that the grinding wheel (2) is provided with a sensing board for an upper electronic limit (3) and a sensing board for a lower electronic limit (4), the host machine body (6) and the host machine shell (17) are respectively provided with an approaching switch. When a hydraulic cylinder lifts up, the upper approaching switch approaches the sensing board for the upper electronic limit, and after reaching a preset distance, the approaching switch gives an electronic signal to stop the hydraulic cylinder, thus enabling a pull rod not to collide with the host machine body, and further preventing
