Smash material mechanism 7 simultaneously and disperse the raw materials in unloading hole 401, and the concrete process is: when the main shaft 9 rotates, the rotating disc 17 and the second hemispherical block 18 are driven to rotate synchronously, when the second hemispherical block 18 contacts the first hemispherical block 706, a thrust force is generated on the first hemispherical block 706, and the thrust force and the elastic force of the material tamping spring 705 act together, so that the horizontal plate 702, the first hemispherical block 706 and the material tamping rod 703 move up and down in a reciprocating manner. The material stirring rod 703 drives the material homogenizing rod 707 to move synchronously in the up-and-down moving process, and the ball 708 rolls in the spiral groove 402 in the process, so that the material homogenizing rod 707 rotates in a reciprocating mode, and raw materials in the blanking hole 401 are uniformly stirred in a rotating mode through the rotating material homogenizing rod 707.
The dispersed raw materials leave the discharging hole 401 and fall to the upper surface of the lower grinding disc 13 and slide down to the position between the lower grinding disc 13 and the upper grinding disc 10 along the upper surface of the lower grinding disc 13, the stone grinding balls 11 grind the raw materials on the upper surface of the lower grinding disc 13, the balls 708 push the stone strips 19 and the lower grinding disc 13 to move downwards when rotating to the position corresponding to the stone strips 19, the lower grinding disc 13 drives the lifting rod 122 to descend to compress the supporting spring 123, after the balls 708 leave the position corresponding to the stone strips 19, the resilience force of the supporting spring 123 enables the stone strips 19 and the lower grinding disc 13 to return upwards, so that the stone strips 19 and the lower grinding disc 13 generate continuous up-and-down vibration, and flour adhered to the lower grinding disc 13 falls off through the up-and-down vibration of the lower grinding disc 13; the raw materials which are not fully ground are prevented from sliding off the lower grinding disc 13 by the action of the material blocking ring 20, and the fully ground flour falls off through a gap between the material blocking ring 20 and the upper grinding disc 10.
The ground material becomes flour and slides down the upper surface of the lower grinding disc 13 until it leaves the upper surface of the lower grinding disc 13. Flour leaving the upper surface of the lower grinding disc 13 passes through the annular channel 14, falls onto the guide block 15, slides downwards along the upper surface of the guide block 15, enters the material receiving box 16 through the discharge hole 101, slides downwards along the bottom surface of the inner side of the material receiving box 16 under the action of gravity, and finally flows out of the discharge hole 161.
