Description

After reducing driving force of the main motor by the gear reducer, when the drive center axis and the quincunx rack fixed on the center axis revolve, under the centrifugal force the roller revolves around the center axis, at the same time parallel swing around the shaft, making the roller compress out side to the ring, thus ensure that the roller and ring has maximum surface contace. At the same time the roller self revolves around the roller shaft, making the material scooped up by the shovel blade to grind, after grinding the powder blew to upper part of the mainframe, the separating by the separator, too coarse powder drops to the grinding room to re-grind, the qualified powder airflows into the cyclone powder collector, through the discharging pipe is qualified product.
