Notes:
All measurements were made grinding wheat.
1. The average handle pressure exerted against the grinder handle knob to grind wheat.
2. Grinder axle torque. Calculated by multiplying the knob pressure by the handle length in feet.
3.Minutes and seconds required to grind one cup of wheat at 60 RPM, stones/burr spacing set at .005 inch. The Family Grain Mill and the Back to Basics Grinder burrs were set tight.
4. Minutes required to grind 10 cups of wheat. This time included putting the wheat through twice with the Family Grain Mill and the Back to Basics Grinder because of their coarse grind on the first pass.
5. The higher the number the finer the flour. See the Flour Fineness Graph for greater detail.
6. This is a measurement of how much energy must be expended in grinding wheat with each grinder. It was calculated by multiplying the grind time by the torque. The energy expended on the second grind for the Diamant, Family Grain Mill and the Back to Basics Grinder was also included in this figure. The lower the number the better.
7. This line compares grinder efficiency to the grinder cost using the Country Living Mill as the base. The higher the number the more efficient the grinder. No other determining factors were used in computing this figure such as grinding speed, durability or long life of the grinder and because of this, these numbers can be misleading on overall grinder value. This is especially true when comparing the Back to Basics and Family Grain Mill. (Figured by dividing the Country Living Mill's power coeficient by the compared grinder's power coeficient then multiplying the result by the cost of the Country Living Mill.)
8. The Diamant will make a fine grind with only one pass but the Diamant test administrator chose to grind the wheat in two passes as he feels it grinds easier this way.
