The ratio of cylinder length to diameter of ball mill is small, and in most cases the ratio is only slightly greater than 1. In addition, the rotating speed of the barrel of the rod mill is lower than that of the ball mill of the same specification, so that the medium in it is in the state of falling.

[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.

Could someone help in finding an analytical answer or formulas for a proper length-diameter ratio of a piston to prevent it from binding as a function of force or pressure, piston diameter, and the clearance between the piston and cylinder bore? The piston can be either connected to a rod or to nothing. Thanks very much in advance.

The rods should be 152 mm shorter than the inside working length of the mill. Rods have a tendency to break during operation; therefore, the quality of rod should be carefully chosen. According to Rowland and Kjos [2], the recommended ratio of rod length to mill working diameter needs to be between 1.4 and 1.6 to yield acceptable life to the rods with minimum breakages.

Rod Design, 2nd ed.) conservatively limits the engagement length L E to a minimum of half of the nut's height h. At this minimum engagement, the reduced allowable rod tension A1 T is considered to be half of its full (basic) allowable A. Partial-T engagement lengths in between 50% and of the nut height result in linear reductions of T A: T A1 = (L E /h)T A
