When properly managed, a two pair high roller mill used for grinding corn or cracking soybeans will wear the top and bottom pairs of rolls at approximately the same rate. By using a "staggered" corrugation on the fast and slow rolls (coarser grooving on the fast roll) all four rolls will be ready for recorrugation at the same time.
Vertical rolling mill has two pairs of grinding rollers. Each pair of roller is composed of two narrow rollers and mounted on the same axis and can rotate at different speeds. The motor driving reducer make grinding plate to rotate. Raw material is sent to the center of the rotating grinding plate by the locking air feeding equipment.
Because of the current demands on mills to process much lighter exit gauges from increased incoming hot strip thickness, much larger reductions are necessary on individual mill stands, such high reductions at a nominal width result in a larger area of contact with corresponding higher rolling force, friction and heat generation (see Fig 1

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 reduce the slab's thickness by as much as 2-½".
The vertical roller mill (VRM) which has gained wide acceptance in the cement industry and is used for grinding raw materials (mainly limestone), is a promising alternative. The VRM dries, grinds, and classifies ores and minerals within a single unit. A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the ...
