Fourth step: when the slurry output of the supporting cylinder 382 needs to be increased, the grouting head 386 is screwed to the left side of the supporting cylinder 382, so that the grouting head 386 moves the arc plates 385 to the side far away from the axis of the supporting cylinder 382, and gaps among the arc plates 385 are gradually increased, thereby being convenient for passing a large amount of slurry; conversely, the grouting head 386 is screwed to the right side of the supporting cylinder 382, so that the grouting head 386 gradually reduces the abutting force to the arc-shaped plates 385, and the arc-shaped plates 385 gradually draw close to one side close to the axis of the supporting cylinder 382 under the action of the supporting spring rod 384, so that gaps among a plurality of arc-shaped plates 385 can be gradually reduced, and the slurry outlet amount of the supporting cylinder 382 can be reduced.
Fifth step: when slurry is poured into the first feed inlet 31, the slurry flows into the conical mesh plate 47 under the guiding action of the circular truncated cone 43, and at this time, the conical mesh plate 47 rotates, so that the conical mesh plate 47 drives the annular groove 48 to rotate, and relative to the conical mesh plate 47, the mounting rod 49 drives the grinding support 40 to rotate along the annular groove 48, so that residual particles in the slurry are convenient to grind, and after the diameter of the particles in the slurry meets the requirement, the particles can flow downwards into the second feed inlet 32 through the conical mesh plate 47.
