The following is the working principle drawing of symmetrical 3 roll bending machine. Driven roller Ⅱ, Ⅲ is driven by motor and reducer, which rotates in the same direction at the same speed (or in the opposite direction). Because of the friction between the roller and the plate, the plate is driven forward and the roller is rotated.

Vertical roller mills are developed to work as air-swept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill). Loesche roller mill and Polysius® roller mills are widely applied in cement raw material grinding.

In contrast, the Roller Mill Grinder Mixer operates at a much slower speed than the Hammer Mill Grinder Mixer. This type of grinder produces a more consistent particle size with increased bulk. The variable parameters of the Roller Mill are feed rate, quality of feed, and power to the Roller Mill and roll spacing.

A mill is designed to work well within its elastic deformation stress range while the work-piece is in its plastic deformation stress range. The yield stress of C12 bronze is 18,000 psi. The area undergoing deformation is most of the contact area between the rollers and the sheet multiplied by the width of the sheet.

When you purchase a new rolling mill it will come heavily greased in oil. That's a good thing! Always keep your rolling mill and rollers greased in a 3-to-1 gear oil which will protect your mill from corrosives. This is especially important during transport via ocean freight, so new mills have a lot of protective grease during transit.

The Kegco KM11GM-3R Grain Mill is perfect for large batches and high efficiency milling. With three rollers, all your grain will be crushed twice in one cycle. The initial crush is through the fixed gap between the top two rollers, and then the grain passes through the second gap between the drive roller and the adjustable bottom third roller.

4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
