Rotationally connected with the transmission mechanism, the driven roller is located under the driving roller, and the bottom of the driven roller is docked with one end of the auger shaft channel 41;

The mill head 3 includes a fixed millstone 33, a first-stage movable millstone 32 and a second-stage movable millstone 31. The fixed millstone 33 is a trumpet-shaped structure, and the small mouth end of the horn is docked with the auger shaft channel. The millstone 32 and the secondary movable millstone 31 are all conical structures, and the first-stage dynamic millstone and the second-stage dynamic millstone are coaxially installed in the fixed millstone successively, and the millstone shaft 35 connecting the first-stage dynamic millstone and the second-stage dynamic millstone is connected to the agitator. Dragon shaft 4 is connected with the shaft center;

Described transmission mechanism comprises motor 14, small belt pulley 13, large belt pulley 10, transmission shaft 11, driving gear 9 and driven gear 8, and described transmission shaft 11 is connected with auger shaft 4 concentrically, and described large belt pulley 10 and The driving gear 9 is installed on the transmission shaft in turn, and the large pulley is connected with the motor 14 through the belt 12 and the small pulley 13. The driving gear meshes with the driven gear installed on the driving roller shaft, and the transmission shaft 11 is in the Driven by the motor, the auger shaft, the grinding disc shaft and the driving roller shaft are driven to rotate synchronously, thereby driving the roller mill and the mill head to rotate.

working principle

When it is necessary to grind the grain, first start the motor 14, then pour the grain into the feed hopper 7, the grain falls into the roller mill from the feed port, and the grain is first broken by the driving roller and the driven roller, and then the grain is crushed by the The auger shaft 4 transmits the crushed grains from the auger shaft channel 41 to the mill head 3. First, the first-stage movable millstone 32 and the fixed millstone 33 grind the grain for the second time, and then the second-stage movable millstone grinds the grain. 31 and the fixed millstone 33 are ground for the third time. Since the distance between the first-stage movable millstone and the fixed millstone is greater than the distance between the second-stage movable millstone and the fixed millstone, the first-stage movable millstone and the fixed millstone cannot be grinded. Larger grains that are sufficiently ground cannot move forward, and the grains are continued to be ground by the first-stage movable millstone and the fixed millstone to ensure that the millstones ground by the second-stage movable millstone and the fixed millstone are fine enough, and finally the ground grains are ground by the Discharge tray 2 flows out. By adjusting the distance between the first-stage movable millstone and the second-stage movable millstone installed on the millstone shaft, the gap between the millstones can be adjusted to meet the grinding needs of powder particles of different sizes.
