Rolling Mill Power Calculation. windseaker1 sorry for being late getting back, yes the bend formula works for rolling as well, when you roll a plate you are bending it on a large radius, the metal still has to shrink on the inside of the neutral line and stretch on the outside get a finished diameter that you want, you have to compensate by adding or subtracting part of the metal ...
mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential ...
Rolling Mill Calculation. 201924power in rolling power is applied to the rolling mill by applying torque to the rolls and by using roll strip tensione total rolling load is distributed over the arc of contactowever, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance a from the line of centers of the rolls.
