Turbo Mill – Ball Mill and Air Classifier Production Line
Turbo Mill is different from other kinds of grinders. Raw materials will be ground via the force of cutting, impact, innumerable high-speed vortexes, and high-frequency vibratory. Not only the raw materials with tough flexibility and high fiber but also high heat-sensitivity can be ground completely. The tapered rotor and stator are adopted, and the gap between …
Christian Pfeiffer classifying lining · Christian Pfeiffer
The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.

Classifying Liners
Some ball mills around there are really a black box. There is very little literature on the subject as you mentioned. The object of classifying liners is to keep coarser balls in one section and smaller in the other section. So basically you want high impact energy in one section and lower in the other section.

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
