Accurate prediction of the rolling force is critical to assuring the quality of the final product in steel manufacturing. Exit thickness of plate for each pass is calculated from roll gap, mill spring, and predicted roll force. Ideal pass scheduling is dependent on a precise prediction of the roll force in each pass. This paper will introduce a concept that allows obtaining the material model ...

Industrial Roller Mill - Williams Crusher. Centrifugal roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, turning materials into small granules or fine powder. Some of its typical applications include the particle size reduction of coal, glass, gypsum, limestone, and more.

To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.

For improved size reduction one of the rolls rotates faster. This results in a differential in speed between the roll pair. Typical differentials range from 1.2:1 to 2.0:1 (fast to slow). Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9-inch (~23 cm) roll to 3,140 feet per minute (~957 m/min) for a 12-inch (~30.5 cm) roll.
