Rolling Mills: What They Are & How They Work What is a Rolling Mill?
At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacrificing any of the material meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level and the desiredRequest PDF On Mar 15, 2015, Mathis Reichert and others published Research of iron ore grinding in a vertical-roller-mill Find, read and cite all the research you need on ResearchGateResearch of iron ore grinding in a vertical-roller-mill

Force Model and Elastic Deformation Analysis of 20-High Sendzimir Mill
A 20-high Sendzimir mill is widely used in cold rolling. The deformation of rolls within the roll system as a whole is analyzed without pin-pointing upon each roll and impact on the rolling process. The mechanical model of the work roll, first intermediate roll, second intermediate driven roll, and second intermediate idler roll was proposed and the through the electrical control system. The parameters of VRM are as follows: roller radius 340 mm, roller width 105 mm, roller inclination 13°, millstone radius 300 mm, millstone revolution rate 0 72 rpm, motor revolution rate 0 1000 rpm, maximum motor power 15 kW, loading pressure 0 10 MPa, feeding rate 0 200 kg/h.

Effects of Blade Parameters on the Flow Field and
The vertical roller mill is an important crushing and grading screening device widely used in many industries. Its classification efficiency and the pressure difference determine the entire producing Roll diameters vary from 0.5 m to 2.8 m, and roll widths vary from 0.2 m to 1.8 m. The recom-mended maximum L/D ratio for hard ores is 0.7:1. The L/D ratio has a very important effect on the properties of the mechanical components, layout of the drive system, performance of the rolls and wear life of the liners.
