Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

For repeatability, the aim is to keep the apron knife constant. The standard way to do this, is to have a hydraulic, or a pneumatic apron set system. These systems will have gauge to show pressure, and a regulator to control this pressure. The photo at the right shows an electro-hydraulic apron set on a typical TRM. ROLL SPEED.
Amtec Block Nuts are custom engineered to meet specific pre-tensioning conditions for rolling mill frames, pinion stands, crop shear housings, plate and strip levelers, injection molding machines, and mechanical or hydraulic presses, to name just a few applications.

the higher the pressure imparted on the film at that cross directional point. Although a subjective evaluation of the Fuji film can be done with the eye to see what part of the press is loaded higher, to get actual values for the pressure a Fuji film reader must be used. A second method for measuring nip impressions with Fuji film is available.

In the discussion that follows, the term rider roll pressure refers to the downward pressure exerted by the weight of the rider roll on the paper rolls. Rider roll relief pressure refers to the hydraulic pressure in the relief cylinders, which helps support the weight of the rider roll, thereby reducing the downward pressure on the paper rolls.
The Edwards mill hydraulic system and accumulators are based on more than 50 years experience in the sugar cane industry. Their primary purpose on mill cap rams is to establish a desired average opening to the mill, subject the cane and bagasse to pressure and increase the mill opening under a yielding force, when necessary.
A few years ago, Freeport-McMoRan Inc. (FCX) chose high-pressure grinding rolls (HPGR) over a semi-autogenous grinding mill for the expansion of its Morenci open-pit copper mine in Arizona. In February of this year, Iamgold announced it too would be using HPGRs at its new Côté Lake project in northern Ontario. The same month, Altura Mining also revealed it would be using HPGRs for …
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 work-rolls through 28:1 gears to …
The hydro-dynamic roll pressing system guarantees high throughput and permanently stable, reproducible pressures in the roll gap.
