This is becoming common whether a 2-high, 4-high, 6-high, or cluster mill. Before dual motor drives, rolls had to be ground the same diameter. If one roll needs to be ground, the opposing roll must be ground at the same diameter. Four-high mills are very common for steel, aluminum, copper, and any high production metal rolling.

In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.

The 3-roller mill has several advantages and few disadvantages. It has greater output than a 2-roller model running at the same RPM. It provides less husk damage, which aids in sparging. Also, the 3-roller mill more fully separates the starch from the husk, while providing superior grain feed, even with wheat.

History of the Rubber Mixing Mill The first rubber machinery used in the rubber industries has a very simple and basic structure. Moving forward to 1820, a manual mill with a single roller was employed for the rubber refining procedure. But sooner, in 1826, the rubber mixing mill with double rollers was introduced and was more rampantly used for rubber processing.

A two-roller mill can do the job just fine in two rounds as per the gap you adjust and the crush size your desire. However, a three-roller mill would do the same in one go by passing the grain through two different gaps. The first would break the husks of the grain while the second grind the grits.

Set the roll nip opening to 2 mm. Adjust and maintain roll temperature at 70 ± 5 degrees C. Add rubber into the mill nip and band, as a continuous sheet, onto the front roll. Using a hand knife, make two ¾-cuts from each side and allow the rubber to move through the nip quite a few times until a smooth rolling bank is formed on the nip.

The 2-roll-refiner crushes sugar crystals to sizes below 100µm. Alternatively, sugar can be ground separately by a sugar mill, which was common practice some decades ago. Although sometimes this set-up can still be found, most companies nowadays prefer the 2-roll-refiner due to the danger of dust explosions in sugar mills.

Using a standard 2-roller homebrew mill, I crushed each malt using four different gap settings. The gap settings were 1.25 mm, 1.0 mm, 0.75 mm and 0.50 mm, and I used a feeler gauge to confirm these gap setting between each milling. After milling, I performed a grain sieve test on the different malts and crushes, and recorded all of the results.

A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1.
