Based on his work, this formula can be derived forball diameter sizingand selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of thesingle-sized ballsin mm.d = the diameter of the largest chunks of ore in themillfeed in mm.

2)Ballmilling – aball millwith a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

Theseball millsare often called planetaryball mills. The rotating drums are not usually detachable -- the material is poured into the top and the cap is replaced, like a kitchen blender. Like allball mills, the speed andball sizehave an effect on how the verticalball millworks.

Generally, a maximum allowed ball size is situated in the range from D /18 to D /24. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed30–35…

1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grainsize, hardness, density, temperature and humidity), the degree of ...

Wiki says "Aball millis a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics." Manyinstructablesrefer to United NuclearBall Mills. Their smallball millcost between $70 and $80 dollars. For no more than $30 and in 5 minute you can build aball millof appreciable performance.
Ball end millshave a rounded nose and create a round-bottomed groove in milling tasks. Also known asball-nose endmills, they are rotated against a workpiece to make round-bottomed slots and pockets ormillcomplex shapes without sharp corners. Each endmillhas flutes on its cutting head that carry chips away from the workpiece to prevent ...
