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.

Bent shaft(s) can create a pinch point and a loose point with each revolution. This will influence the speed of the product. 2. Depending on the roll ...
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.
The hydraulic motor provides a flow of 12 GPM. Magnets in either of the machines remove any metal that may accidentally mix with the material entering the mill. The 240 degree swing radius of the unloading auger allows repositioning of the discharge auger from one side of the machine to the other without moving the grinder-mixer.
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 …
Freeport's Morenci operation, for example, commissioned a 3.0 x 2.0-m HPGR (called the hydraulic rolls crusher, or HRC) in an expansion mill circuit in 2014. The circuit has a single-line capacity of over 60,000 tpd. with the single HRC having 11.4 MW of installed power, and operating in conjunction with twin MP1250 cone crushers to ...

the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.
