Introduction to Milling Tools and Their Application
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

The motion of grinding bodies in conventional ball mills has been repeatedly investigated, both theoretically and experimentally. It is well‐known that, depending on mill filling and speed of rotation, different motion patterns occur and some of these patterns, especially that of cataracting, can be described by simplified theories.

Comminution - an overview | ScienceDirect Topics
The parameter M i takes on different values depending on the comminution machine: M ia for primary tumbling mills (AG/SAG mills) that applies above 750 μm; M ib for secondary tumbling mills (e.g., ball mills) that applies below 750 μm; M ic for conventional crushers; and M ih for HPGRs. The values for M ia, M ic, and M ih were developed using the SMC Test® combined …

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
Theories of ball wear and the results of a marked-ball ...
Theories of Ball Wear The volume and surface theories of ball wear were proposed by Davis3 and Prentice4 respectively. Their discussions relate mainly to the size distribution of balls within a mill. The theories predict markedly different distributions of ball size. According to the volume theory the size frequency distribution is hyperbolic,

Each of these theories was useful in the design and scale up of' ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation. Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range.
