Posted June 11, 2009 (edited) with the encouragement of Dave Stephens i have started building several roller mills based on Hugh McDonald's design. I am going to build several extra of the parts that require mill work or lathe work if anybody else is interested. I have re done the orignial plans to all english dimensions and parts.

Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.

Milling malt for a normal brew should not take more than 1 h to 2 h. The time depends on the length of the rollers, the moisture content of the malt, the roller speed, and the type of roller surface. In some roller mills, the grist may be separated by size and some grist fractions may be sent through the mill a second or even third time.

Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.
