When the push shaft on the turntable one rotates into the chute, during the continuous rotation, the turntable two is pushed to rotate. Through the rotation of the turntable two, the cam is driven to rotate, so that the slide bar slides, the spring is compressed, and the valve opens. When the cam disengages from the arc-shaped guide rail, the spring resets and the valve closes. By intermittently supplementing water, the fluidity and solid-liquid ratio of the slurry can be adjusted in real time, avoiding insufficient contact between the grinding medium and the material caused by too thick slurry, or energy loss caused by too thin slurry.
