when the quartz sand falls to the side wall of the baffle plate 52, the rotating wheel 522 is driven to rotate by the motor, so as to drive the transmission belt 523 to perform transmission action, at the moment, the quartz sand with higher iron content is adsorbed under the action of the magnet rod 51 and then moves along the transmission belt 523, in order to avoid that part of the quartz sand with lower iron content is also transported into the conical tube 11 along with the transmission belt 523, the magnet rod 51 is obliquely arranged on the transmission belt 523, the magnet rod 51 is obliquely directed to the bottom end of the shell 1, and a 45-degree included angle is formed between the magnet rod 51 and the transmission belt 523, so that the resistance of the magnet rod 51 to the quartz sand except the magnetic force is smaller than the gravity of the quartz sand, thereby effectively avoiding misjudgment of the magnetism of the quartz sand, and after the elastic sheet 524 is arranged on the side wall of the through hole 521, the elastic sheet 524 can also block the quartz sand, so that the quartz sand is prevented from sliding into the tapered tube 11 from a gap between the through hole 521 and the transmission belt 523; when the quartz sand with low iron content slides along the side wall of the baffle plate 52 after passing through the transmission belt 523, the first rolling wheel 12 is driven to rotate when the quartz sand passes through the first rolling wheel 12, the second rolling wheel 13 is driven to rotate after the first rolling wheel 12 rotates, the quartz sand is further screened due to the magnetism of the second rolling wheel 13, the quartz sand with high iron content is adsorbed on the surface, and when the second rolling wheel 13 passes through the branch pipe 111, the quartz sand with high iron content on the surface of the second rolling wheel 13 is cleaned and brushed down under the action of the cleaning brush 112 and flows into the tapered pipe 11 along the branch pipe 111, so that the screening effect on the quartz sand is further ensured; after the quartz sand is put into the grinder, the cylinder 2 is controlled to extend, so that the motor 41 on the fixing plate 3 is pushed to move towards the sieve plate 44, when the grinding ball 43 is moved to be in contact with the annular sliding groove 441, the cylinder 2 stops working, the motor 41 is controlled to be powered on and rotate, the grinding ball 43 is driven to slide in the annular sliding groove 441 through the grinding plate 42 in the rotating process of the motor 41, the quartz sand is ground in the sliding process of the grinding ball 43, and the depth of the annular sliding groove 441 is in a high-low intermittent fluctuating shape, so that the alternating frequency between the quartz sand in the annular sliding groove 441 and the quartz sand on the sieve plate 44 is enhanced, and the uniformity and the universality of grinding the quartz sand are ensured.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
