The sample is better screened on the vibrating screen 53.

In one embodiment of the present invention, the simple inspection sample grinding device further includes a splash guard 28 for preventing the material from splashing. The splash guard 28 is fixed on the inner wall of the grinding bin 21, and the splash guard 28 is located above the material receiving opening 26. When a sample is ground in the grinding bin 21, since the material receiving opening 26 is formed in the side wall of the grinding bin 21 for recovering a sample with a larger particle size, there is a possibility that the material may spill from the material receiving opening 26 during grinding, one end of the splash-proof plate 28 is fixed above the material receiving opening 26, and the other end is disposed obliquely downward. Not only can the materials smoothly enter the grinding bin 21 from the material receiving opening 26, but also the materials in the grinding bin 21 can be prevented from splashing from the material receiving opening 26.

The sample to be tested is fed from the feed tube 11 and falls down the feed tube 11 into the grinding silo 21. After all the materials to be ground enter the grinding bin 21, the grinding is started immediately. The motor 4 is started, and the motor 4 is started to drive the main transmission shaft 61 to rotate. The main drive shaft 61 rotates to rotate the grinding roller 22 attached to the lower end. The grinding roller 22 in this embodiment is configured to conform to the inner wall of the grinding chamber 21, leaving a narrow space therebetween for the placement of material. The grinding roller 22 rotates to cooperate with the grinding balls 23 on the side wall and the inner wall of the grinding bin 21 to impact and grind the block sample. The ground sample falls downward under the influence of gravity. Some of the samples are ground into fine particles, which is convenient for subsequent detection, but some of the samples still remain large particles, which is not beneficial for subsequent detection. The samples are mixed together and output from a discharge pipe 25 at the bottom of the grinding bin 21. These sample discharge pipes 25 having different particle sizes are filtered by two screens 53 during their falling. The two screens 53 arranged one above the other have different mesh sizes, the upper screen 53 having a smaller mesh size than the lower screen, so that the upper screen 53 performs a coarser filtering operation, while the lower screen 53 performs a finer filtering operation. The filtering efficiency can be accelerated by two filtering steps of one coarse filtering step and one fine filtering step. The finely ground sample can be discharged from the outlet of the discharge pipe 25 through the two screens 53.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
