Roller mill is a form of compression mill that uses a single, double or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling ''broadside'' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"diameter workrolls through 28:1 gears to reduce the slab''s thickness by as much as 2 .

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Fourroller mills Fourroller mills have two sets of rollers. When using a fourroller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits.

This provides sufficient rigidity and, at the same time, resiliency, necessary to roll parts of varying thickness. Two Roll vs. Three Roll Process. Note that the drawbacks of the three roll systems, whether pinch or pyramid type, are that the work piece is not confined during the bending process,, bending takes place "in the air."
