A steel rolling mill produces a sheet of uniform thickness from a slab of steel. It typically consists of several rolling stages, with rollers in each stage compressing the sheet of steel passing through it (Figure 1). In between the roller stages, looper stages maintain the tension in the sheet and prevent tearing and formation of slack.
Cold Rolling – Process Overview - Matmatch
The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. ...

Amazon: metal rolling mill
Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used. If the rolls are grooved, a tearing or grinding component is introduced.

DE-11: Lesson 43. SIZE REDUCTION - e-Krishi Shiksha
For example, in most roller mills compression is the dominant force, impact forces feature strongly in hammer mills and shear forces are dominant in disc attrition The extent of the breakdown of a material may be expressed by the reduction ratio, which is the average size of the feed particles divided by the average size of the products particles.

Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90°C. During subsequent compression and extrusion through holes in a ring' die, friction further increases feed temperature to nearly 92°C.

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. One of the rollers is run by a motor and the others are rotated by friction as the material is drawn ...
Tandem rolling mill - Wikipedia
If the Mill Stand Spring curve and the Compression Curve for the Strip are drawn against the same distance axes, then the intersection point gives the solution of expected Rolling Force F, and final Strip Thickness h, and also the required initial Screw-down position So.. In its simplest form h = S – S o – (F – F o) / M equation 4. This equation is known as the BISRA equation.
