PARTICLE SIZE REDUCTION TECHNIQUES - SlideShare
BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume.

Grinding Mill Design & Ball Mill Manufacturer
All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

Grinding Media - 911Metallurgist
Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ...

3D Pocket Clearing - manual Stepover for Ball endmills ...
If you are using an 8mm ball mill, then 6mm stepover is still very aggressive and will leave a very irregular surface for the finish pass. The goal is to get as uniform a surface as possible for the finish pass so the cutter bends by a uniform amount. Any change is the amount of force on the cutter will show up on the surface of the finish cut.
