A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. The metal changes its shape gradually during the period in which it is in contact with the two rollers.
The roller mill at the turn of the century is perhaps epitomised by Vernon & Sons' mill at Birkenhead, Liverpool which opened in 1899. Built on the latest Simon system, the mill had two separate milling plants, one with nine 60 inch and twenty-seven 40 inch rolls, the other with nine 60 inch and thirty-five 40 inch rolls. ...

In these studies, evaluating the energy use of a hammer mill vs. a conventional roller mill, a traditional roller grinder has been shown to consume 20-30% less energy. However, when comparing an RMS VersaMill® to a hammer mill, the required kilowatts to grind a ton of grain through a VersaMill® is approximately 40-60% more energy efficient .
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.
vertical roller grinding mills for grinding: • Coal • Cement raw material • Clinker / granulated slag • Industrial minerals, and • Ores The core elements of these plants are the Loesche vertical mills for dry-grinding the above-mentioned grinding stock. Loesche has developed and built the largest and most
Automatic Roller Mill. Automatic's electric roller mills use parallel, corrugated steel rolls to produce precise particle size—every time. Automatic's one-fast-roll principle gives more capacity at up to a third less horsepower than with hammer mills. It also provides a self-cleaning action that prevents clogging or packing.

2. Feed the dry metal into the mill, applying snug (but not overpowering) pressure on rollers. 3. After rolling metal through the mill, flip the piece end to end before you roll it through again. You will get a more even roll. 4. Before passing the metal through the rollers, lower the rollers until you again have a snug fit (as in step 2). 5.
Structure diagram of barrel roller mill. Full size image. The biggest difference between the horizontal cylinder roller mill and other grinding equipment is that the inner wall of the rotating hollow cylinder is used as the extrusion surface to squeeze the material. The vertical mill is "cylindrical surface plus plane," the roller presser ...
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 ...
Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 45–70% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.
The history of two roll mill and development . Two roll mill is the earliest used in the rubber industry, simple structure of the most basic rubber machinery. As early as 1820, a manual – driven single – roller trough rubber refining machine. Double-roller rubber mixing machine has been used in rubber processing in 1826.
