Milling Actions Grinding, or de-agglomeration, is affected by impact, pressure and shear forces between the grinding media and the mill parts. In each situation there is a critical energy required to break target particles. This 'Stress Energy' (SE) is directly proportional to the bead size: SE ∞ p . V2 . d3, where p = bead density

Reproducible sample preparation for determining moisture. Due to the milling system's special design, heating of the grist and loss of moisture during the milling process is reduced. The SM 4 is therefore especially well suited to preparing samples for moisture determination, as well as for analyses of protein or fat content, for example.

During milling, the breakage of wheat kernels during first break roller milling depends on many factors, including the disposition of the fluted rolls. Dull-to-dull gives slippage between the flutes and the kernel, and thus imparts less shear strain than sharp-to-sharp. The planes with principal strain are shown in Figure 2.

For the first stage of grinding, media will generally be in the 4″ to 2″ size (in some cases as high as 5″). In secondary finer grinding the initial charge will begin at around 3″ and in the case of balls will grade down to about ¾". Extremely fine grinding will dictate the use of 1½" and smaller balls. Grinding media is the working part of a mill.

Breaks generally can be evaluated on screen sizes of 0.630-4.00 mm with semolina granulation measured between .125-1.120 mm and sifting performance between 0.075-0.200 mm. The size spread between sieves should be minimal if the data is to be used to develop granulation curves to evaluate proposed clothing changes in the milling process.
