The three roller vertical mill is placed within a grid-like space where everything seems measured and under control. The image suggests that the human labor needed to work this mill is so minimal that one white woman, dressed as a servant, can operate it—although one might worry about that dainty hand, so close to the powerful rollers.
In this type of mill, the rollers are both adjustable. In these mills, rotation of that two rolls is made in two different directions. In this operation, the metal is passed between two rollers that rotate at the same speed but it is in the opposite direction. It is used in slabbing, plumbing, rail, plate roughing work and many other areas.
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.
1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills. However, control of sheet thickness and cross-section is a real challenge. In order to continuously monitor the thickness of sheets rolled, x …
The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.

The milling process. Before it enters the mill floor, wheat is cleaned and then conditioned after which it passes through two cast steel 'break' rollers which are set slightly apart from each other. The top roller runs at a slightly faster rate to the lower roller and when wheat passes through it creates a shearing action, opening up the ...
For improved size reduction one of the rolls rotates faster. This results in a differential in speed between the roll pair. Typical differentials range from 1.2:1 to 2.0:1 (fast to slow). Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9-inch (~23 cm) roll to 3,140 feet per minute (~957 m/min) for a 12-inch (~30.5 cm) roll.
