The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

from fresh replacements to those which have worn down Actual diameters in use range from 25 to 150mm The smaller the rods the larger is the total surface area and hence the greater is the grinding efficiency A coarse feed or product normally requires larger rods Generally, rods should be removed when they are worn down to about 25 mm in diameter or less, depending on the application, as small ...

Boring bars are made of different materials, and they all have different diameter to length ratios. Where one boring bar will work, another may not. In boring applications, the diameter to length ratio is the biggest contributor to vibration. The most common materials for boring bars and their diameter to length …

Ever asked what size/length rods (bars) you need for charging your rod mill? It depends on the rod mill diameter itself. To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly.

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. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill. Autogenous or autogenic mills are so-called ...

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.

Aug 12, 2014· Depending upon the criteria of each application, the actual ratio may be larger or smaller than 2:1.

Ratio "n" = Rod Length ÷ Stroke The rod's length is measured (for this purpose) from the center of the piston-pin opening to the center of the big-end bore, not overall. 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.
