ABSTRACT:
The present invention relates to provide an upright lever pressure type mill, and particularly to a mill which may enable the internal mill wheel to hold tightly against the external mill wheel to a preset pressure based on the principle of leverage in order to increase milling efficiency, reduce noise and protect mill wheels against wearing. The mill includes a powder suction/delivery device, a separation device, a milling device, a lever pressure device, a variable speed mechanism and a transmission device. The milling device includes an integrally molded external mill wheel, a centrifugal disc and a number of internal mill wheels. The spindle of the internal mill wheel has a pressure lever for mounting a tension spring and for giving necessary tensile force as required on the principle of leverage.
