The ball milling of flowable materials can be optimized by switching to a three roll mill. Not all ball mill applications can be processed in a three roll mill but many are suitable especially pastes and slurries of moderate viscosity. Three roll mill, theory of operation Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

14-1-2014I use a 2-flute ball nose end mill for drilling into ABS all the time, but I would be cautious in other materials. In that parts case, it was being run on my Fadal, which takes about 15 seconds to change tools. Drilling that hole and doing a little profiling with that end mill was the only things that needed to be done.
Mills theory is completely determined, and by quantizing it one can obtain the standard model3. Once you've read the notes, you should understand the basic equations of Yang-Mills 2I believe it was Weyl. I haven't read the original papers, and am relying on hearsay. 3Almost.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
Critical theory as it is known today can be traced to Marx's critiques of the economy and society. It is inspired greatly by Marx's theoretical formulation of the relationship between economic base and ideological superstructure and focuses on how power and domination operate.

Mechanics inside a Ball Mill. In the endeavor to determine the best working conditions for the ball-mill, a detailed mathematical study was made of the action of the ball charge. While the data taken from a properly conducted test are convincing, an engineer sometimes prefers a mathematical proof.
Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in

Grinding Theory: There are a lot of misconceptions about what goes on in a ball mill.
Mills further suggested that sociologists could use the sociological imagination to examine the problems facing society from an outward perspective. Going back to unemployment, a sociologist might observe that in a country of one million people, having five hundred citizens unemployed would be less urgent of an issue than five hundred unemployed in a community of one thousand.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
