After the motor 8 is started, the motor 8 drives the spindle assembly to rotate at a high speed through the coupler 81, and the hammer 53 on the hammer plate 51 is opened under the action of centrifugal force and rotates at a high speed along with the spindle 5. After the material flows down along the funnel-shaped material guiding plate 25 at the feeding opening 21, the material is hit by the hammer 53 rotating at high speed. After the material is hit to be less than the sieve pore size of the arc-shaped screen 3, the material flows into the funnel-shaped discharging plate 26 along with the slurry and then enters the next treatment process.

When the hammer 53 needs to be replaced, the fixing effect of the fixing piece 7 on the side door 6 is firstly released, then the side door 6 is pulled through the handle to rotate, the bottom end of the side door 6 is enabled to be abutted against the ball 14, and at the moment, the side door 6 can be pulled to be far away from the box body 2. Subsequently, the arc-shaped outer press bar 33 corresponding to the upper screen 34 is removed to take out the upper screen 34, or all the arc-shaped outer press bars 33 are removed to take out all the components of the arc-shaped screen 3. At this time, the through holes 23 on both sides of the box 2 are opened, so that the abutting rod 524 on the connecting rod 52 corresponding to the hammer 53 to be replaced can be screwed out.

When the hammer 53 is replaced, the hammer 53 and the spacer 9 are placed at the designated positions, and then the connecting rod 52 passes through the designated positions. When the stop block 527 is locked into the corresponding stop ring groove 58 during the process of the connecting rod 52 passing through the shaft hole 57, the hammer 53 and the spacer 9, a "snap" impact sound is generated, which indicates that the connecting rod 52 is installed in place. After the connecting rod 52 is installed, the abutting rod 524 is screwed into the threaded hole 523 in the connecting rod 52, and at this time, the abutting rod 524 abuts against the sliding block 525, so that the sliding block 525 cannot move. Subsequently, the screen assembly, the end cap 24 and the side door 6 are mounted, and the pulper can be used continuously.
