In the milling process, scraps generated on the end cover piece 101 drop downwards into the first collecting shell 5 and gradually subside downwards, the scraps and the milling liquid are automatically layered in the process, namely, the scraps subside to the bottom of the first collecting shell 5, and the liquid return pipe 6 absorbs the milling liquid at the middle upper part in the first collecting shell 5, so that the scraps in the milling liquid are filtered, a filter screen is directly used for filtering a large amount of scraps in a traditional filtering mode, blockage is easy to occur, the absorption amount of the milling liquid in the first collecting shell 5 by the liquid return pipe 6 cannot reach the amount required by a cooling system, the milling part of the end cover piece 101 cannot be sufficiently cooled, and the quality of milling processing is reduced.

In the process that the first sliding rod 9 rotates anticlockwise along with the rotating roller 7, when the interception plate 8 (moving to the lower side) is in contact with the first stop lever 12, the interception plate 8 at the lower side deflects clockwise (in the front view direction) along with the continuous anticlockwise rotation of the rotating roller 7, the adjacent first elastic element 10 deforms, after the interception plate 8 at the lower side rotates anticlockwise along with the rotating roller 7 and passes through the first stop lever 12, the interception plate 8 at the lower side starts to reset rapidly (namely reversely deflect) under the action of the torsion force of the adjacent first elastic element 10, then the interception plate 8 in the rapid reset is contacted with the second stop lever 13, so that the intercepted fragments on the interception plate 8 are separated under the action of inertia, the normal passing property of milling liquid of the interception plate 8 is ensured, the interception plate 8 deflects clockwise again under the action of the blocking of the second stop lever 13, the interception plate 8 is reset again along with the anticlockwise rotation of the rotating roller 7, the milling liquid in the right adjacent area is moved rightwards, the milling liquid is utilized to carry away the left fragments by the rightwards moving milling liquid, the fragments in the process are carried out by the opposite directions through the two guide pieces 16, and the fragments are collected downwards from the middle part 5, and the fragments are collected downwards after the fragments are guided downwards from the shell.
In the process of rotating the rotating roller 7 anticlockwise, after the limit post on the first sliding rod 9 (moving to the right lower side) enters the middle groove 11033 on the right side, the limit post on the first sliding rod 9 on the right lower side starts to move towards the direction close to the axis of the rotating roller 7 under the extrusion action of the adjacent middle groove 11033, the first sliding rod 9 drives the upper part of the first sliding rod to move together, the interception plate 8 starts to retract, and when the limit post of the first sliding rod 9 (moving to the right side) enters the adjacent second arc groove 11032, the interception plate 8 completely retracts, so that fine scraps in milling liquid in the middle space 102 are continuously intercepted through the circular movement.
