The vertical roller mill is widely used in the fields of cement, electricity, steel, nonmetallic ore, etc., it can grind cement raw materials, slag, coal, etc. into powder.; 1. Vertical Roller Mill Structural Features Automatic roller lifting and falling helps to realize no-load start, so as to lessen starting torque and avoid feeding firstly in the test run.
Abstract –In hot rolling mill process the rollers is subjected to heating and cooling cycles with different processing parameter. This nature of heat and processing parameter found some cracks, wear and tear in hot roller. In this work, the study of existing process was done to find the root cause of the cracks in roller mills.

Control decision-making. 1. Introduction. Vertical roller mill (VRM) is a type of heavy-duty and energy-intensive grinding equipment for many industries, such as cement, steel and chemical industries. It is used to grind slag, nonmetallic ore and other block and granular raw materials into required powder materials.
In this study, pilot scale tests were performed with a mobile vertical-roller-mill grinding plant to investigate the relationships between operational parameters. The identification and quantification of the grinding parameter relationships was carried out to implement these relationships into a computational vertical-roller-mill performance model.
