Usually a tube mill can form radii down to between 2.5 to 3 times the material thickness. Figure 3 This typical sizing section of a tube mill has round roll stands with specialty reshaping stands toward the exit. Material flow is left to right. Welded roll forming mills have a different tooling setup that allows for tight, accurate radii.
Mill type These conditions have been built into factors which are given in the figure above. The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000 where: W = weight of charge C = distance of centre of gravity or charge from centre of mill in feet
The speed of revolution of tube mills varies with the diameter. Krupp uses the formula 32/√D for the correct number of revolutions per minute, where D = internal diameters in metres. The Davidsen formula is 200/√D, where D is the diameter in inches.
