Grinding and Screening. In addition to a grain mill, if you want to make grits, you will need three bowls and a couple of screen type strainers. One of the strainers has to have 1/16 inch screen and the other 1/32 inch screen. This will allow you to screen away the larger pieces and re-grind them, as well as separate the grits size pieces from ...
Nowadays, grinding aids are mainly established in continuously operated industrial grinding processes. However, as laboratory mills are often seen as the more convenient tool for an efficient grinding aid screening, most of the present studies were carried out in batch-wise operated grinding devices on laboratory scale.
