In equation 8.14, D is the diameter inside the mill liners and Le is the effective length of the mill including the conical ends. ! c is the specific gravity of the charge and . and / are factors that account for the fractional filling and the speed of rotation respectively. K is a calibration constant that varies with the type of discharge.
There is a small range of ratios for most conventional piston engines: the rod is between roughly 1.4 and 2.2 times the stroke length. It's not possible for the rod to be the same length as the stroke, and rods much longer than twice the stroke make the motor very tall, and are not practical for most purposes (although used for racing).

The length-to-inside diameter ratio of a rod mill was 1.5 when the length was 4.72 m. The true densities of the grinding media and the ore were 8.0 and 2.35 t/m 3, respectively. Forty percent of the mill volume was filled with grinding rods. chat online. Mill (grinding) - Wikipedia.
Feb 06, 2009· The tool's length-to-diameter ratio is significant in any milling process. The larger the ratio, the less rigid the setup. However, the difference in performance between different levels of L:D becomes even more pronounced when tools are particularly small. This video shows machining footage involving tools as small as 0.008 inch in diameter.

2. The ratio between the length and diameter of the barrel of the rod mill is generally 1.5-2.0, and the inner surface of the lining plate on the end cover should be a vertical plane.The ratio of cylinder length to diameter of ball mill is small, and in most cases the ratio is only slightly greater than 1.
As the length to diameter ratio of the mill should be in the range of 1,2-1,5, the biggest rod mill will convert maximum 1500 kW. Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials).
[citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter.
The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.
