A six mil reinforced film can be considered "heavy duty" when it is used to cover a desk to keep it clear of dust. That same "heavy duty sheet" would not be strong enough to line a land fill. Understanding the strength and thickness of the film, it's composition and additives and chemical make-up as well as the job it has to perform will help ...

Tandem Rolling Process :: Total Materia Article
Tandem cold rolling mills are named by their stand arrangement and designed as "sheet mills" if they reduce hot band to sheet gauge or "tin mills" if they roll the same incoming material to tinplate stock. A typical five stand tandem cold rolling mill is illustrated in Figure 1. Figure 1: A typical five stand tandem cold rolling mill

THE MECHANICS OF TENSION CONTROL
For example, if you start with a 17.5 inch roll radius (35 inch diameter) and unwind down to a 1.75 inch core radius (3.5 inch diameter); 17.5 divided by 1.75 is 10:1 ratio. That means, if you start at 100 inch pounds of torque at the beginning of the unwind roll for

Roll Mill - an overview | ScienceDirect Topics
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.
STRUCTURAL STEEL DRAWINGS
The edges of bars usually are rolled square, like universal mill plates. The dimensions are expressed in a similar manner as that for plates, for instance, bar 6 inches by 1/2 inch. Bars are available in a variety of cross-sectional shapes—round, hexagonal, octagonal, square, and flat. Four different shapes are illustrated in Figure 7-5.

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Tandem rolling mill - Wikipedia
A Tandem rolling mill is a Rolling mill with 2 or more close-coupled Stands, each of which is setup for rolling by using its Spring Curve and the Compressive Curve of the metal so that both the Rolling Force and the exit thickness of each Stand are determined.. The main advantages of a Tandem Mill are: only one single pass is required which saves time and increases production; …
