[0051] The working principle of the present application is: when the present device is used, the hydraulic push rod 9 is started to drive the static grinding disc 8 to make the second lining plate 5 descend through the clamping mechanism 2 until the second lining plate 5 is lowered to an appropriate height, then the receiving ring 10 is started to drive the dynamic grinding disc 1 and the lifting support 3010 to rotate through the connecting rotating frame 308, at the same time, the first lining plate 4 is driven by the dynamic grinding disc 1 to rotate at high speed through the clamping mechanism 2, in this process, the receiving ring 10 and the annular sleeve plate 16 rotate synchronously under the driving of the dynamic grinding disc 1, at this time, the annular sleeve plate 16 can be limited in rotation through the limiting ring 14, then the material is sent into the space between the second lining plate 5 and the first lining plate 4 through the feeding port 6, at the same time, the material sliding along the upper surface of the static grinding disc 8 can be blocked through the blocking ring 7, at this time, the material can be ground through the high-speed rotation of the first lining plate 4 and the stationary second lining plate 5, at the same time, the material ground into powder is separated from the outer wall of the first lining plate 4 under the centrifugal force of the rotating first lining plate 4 and contacts with the inner wall of the receiving ring 10, at this time, the powder can be automatically collected through the blocking of the receiving ring 10.

[0052] When the first liner 4 and the second liner 5 need to be replaced, the hydraulic push rod 9 drives the second liner 5 to contact the upper surface of the first liner 4, at this time, the knob 209 drives the rotating disc 204 in the static grinding disc 8 to rotate, and the plurality of moving slide rods 203 drive the positioning insert plate 206 to slide along the inner wall of the linear sliding groove 2016 through the connecting slide plate 202 and the arc-shaped sliding groove 207 under the driving of the rotating disc 204, at this time, the positioning insert plate 206 is pressed against the outer wall of the fixed rod 205 to shrink the first spring 201 until the positioning insert plate 206 is completely separated from the inner wall of the static grinding disc 8, and the positioning slot 208 is moved below the positioning clamping block 2010 under the driving of the rotating disc 204, at this time, the second spring 2013 drives the positioning clamping block 2010 to be clamped into the positioning slot 208 through the rebounding of the moving pull plate 2014, and the connecting pull block 2011 is lowered under the driving of the moving pull plate 2014, so that the rotating disc 204 is clamped and limited, then the hydraulic push rod 9 drives the static grinding disc 8 to rise, at this time, the second liner 5 is completely separated from the static grinding disc 8 and the butt joint insert plate 2015, so that the butt joint of the second liner 5 and the static grinding disc 8 can be quickly released.

[0053] Then the hydraulic push rod 9 drives the static grinding disc 8 to continue to rise until the static grinding disc 8 presses the moving sleeve plate 3012 to rise, in this process, one transmission tooth plate 301 is driven by the moving sleeve plate 3012 to rotate the gear 3011, and the other transmission tooth plate 301 is driven by the gear 3011 to drive the lifting slide plate 302 to descend along the inner wall of the support frame 11 and the support column 15, at this time, the linkage ring 304 is driven by the moving pull ring 309 to descend the lifting sleeve 305 through the lifting bracket 3010, and the transmission rotating rod 306 is rotated under the driving of the lifting sleeve 305 through the guiding sliding groove, at this time, the rotating disc 204 in the first liner 4 is synchronously rotated under the driving of the transmission rotating rod 306, and the positioning insert plate 206 is driven by the moving slide rod 203, the connecting slide plate 202, the arc-shaped sliding groove 207 and the linear sliding groove 2016 to slide into the butt joint insert plate 2015, then the first liner 4 is removed from the upper surface of the driven grinding disc 1, so that the first liner 4, the butt joint insert plate 2015 and the driven grinding disc 1 are separated from each other, thereby realizing automatic release of the butt joint of the driven grinding disc 1 and the first liner 4.

[0054] Then the above operation is reversed, the new first liner 4 and the second liner 5 are respectively butt jointed and fixed with the driven grinding disc 1 and the static grinding disc 8, thereby realizing the purpose of further improving the replacement efficiency of the first liner 4 and the second liner 5.

[0055] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
