selection function rod milling. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore.
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).

Connecting rod Function: The pull and push in the piston receive the piston pin, then the connecting rod acts as the transfer of the pull and pushes from the piston pin to the crank pin. That is, in any internal combustion engine with the help of it, the reciprocating motion is converted to rotary motion.
A rod mill discharge is to be classified in a straight sided, single pitch screw classifier. ... [35] developed a model to describe the relationship between the grinding selection function (breakage rate) and the physio-mechanical properties of the rocks. The advantage in such a relationship lies in the wealth of rock strength data determined ...

function of the wavelength of light and so to convert from radiometric units to photometric units first requires knowledge of the light source. If the source is specified as having a certain color temperature we can assume that its spectral radiance emittance is the same as a perfect black body radiator and use Planck's law. W. Wang
