Milling Formulas Speed (RPM) = (SFM x 3.82) / D Feed (IPM) = RPM x FPT x Z SFM (Surface Feet per Minute) = (RPM x D) / 3.82 IPT (Inches per Tooth) = (IPM / RPM) / Z MRR (Cubic Inches per Minute) = IPM * WOC * DOC AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf mf - steel = 1 mf - gray iron = .65

These days, the vertical roller mills have been widely adopted. A）Structure (1) The rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table. (2) The classifier is housed above the rollers. B）Feature (1) The power consumption level for grinding is lower than that of tube (ball) mill.
