## Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed .

## Milling A Convex Shape With A Ball End Mill

Apr 03, 2011 · The tool path for a convex hemisphere with a ball end mill is indeed a series of circles. The issue is that the diameter of the circles does NOT change linearly with Z. Just like roughing it out with a square end mill - near the top you increase diameter by say 0.002 and reduce Z height by 0.000,5.

Countersink Calculator This will calculate the z depth to enter for a given diameter and angle of countersink. The actual cut dimension will probably be more after cutting due to the countersink point on the tool is usually not perfect causing the tool to cut deeper. So be sure to adjust your numbers so as not to cut too deep.

## Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
