The Significance of Fine Grinding - biodynamics

Marshall's remarks about grinding clay crystals (of less than 2 microns) to support his own ideas about grinding silica crystals down to 75 microns (200 mesh). The fact that 75-micron silica particles are at least an order of magnitude larger than either clay crystals or their ground products turns out to be quite significant.

Grain Processing: Is it Too Coarse or Too Fine? - Dairy Cattle

A course rolled grain has a higher PI than fine rolled grain. In a study where cows were fed 31% barley silage, 8% alfalfa hay and 42.5% steam rolled barley, decreasing the PI from 81 to 72.5% resulted in a 14% increase in milk production because of the increased DMI and dry matter digestibility (Table 7).

The back-end process: Step 3 – Wafer backgrinding ...

For wafers with diameters of 200 mm, it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical two-step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.
