The Wet dry feldspar ball mills is mainly subjected to periodic high-frequency stress. The force is the greatest at the lowest point of the mill and decreases as it rotates to the upper part. The grinding balls slide relative to the material during the rising stage, and the grinding balls impact and crush the material during the falling stage. The balls can be divided into five areas in the mill cylinder
(as shown in the figure)
I: Drop zone: The steel ball detaches from the cylinder and falls in a parabola;
II: Crushing zone: The ball, material, and liner collide, and the material is crushed by impact;
II: Sliding zone: The ball slides downward, the balls rub against the material, and the material is crushed;
IV: Grinding zone: As the cylinder rotates, the balls and the material roll or slide relative to the liner, and the balls exert pressure on the material to grind it;
V: Dead zone: There is basically no relative movement between the balls and the material, and there is almost no crushing and grinding in this zone.
