A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.
MATERIAL-SPECIFIC END MILLS HARDENED STEELS 76 Click Tool for stock, speeds & feeds, & other technical info Designed to mill hardened tool, die, and mold steels up to 55Rc Also excellent for stainless steel, inconel, titanium, and other high temperature alloys 5 flute, variable helix design (approx. 37°) for improved slotting and roughing
These tools, in either straight or ball end configuration, can produce intricate shapes in very hard steel (H>55Rc), quickly and without grinding. However to reach into small features, the length of the tool becomes large enough (length/diameter ratio >5/1) to influence the dimensional tolerances of the machined part due to deflection of the tool.
is the ball diameter, d bmax is the maximum ball diameter in charge, d bmin is the minimum ball diameter which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size ...
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters.

Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter. The general idea behind the ball mill is an ancient one, but it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built. It is reported to have been used for grinding ...

For fine grinding of e.g. sands, balls can be replaced by cylpebs, which are heat treated steel cylinders with a diameter of 12-40 mm and with the same length as the diameter. Ball mills are often used as secondary grinding mills and for regrinding of middlings in concentrators. Ball mills can be of the overflow or of the grate discharge type.

Data from Rowland indicate that the length-to-diameter ratio of mills ranges from 1.2 to 2.3. The largest length mill is around 7 m. The ratio of the length of rod to mill diameter should be greater than 1.25 to avoid the risk of rod tangling. The recommended ratio is 1.4 to 1.6.
