TECHNICAL NOTESGRINDING R. P. King

 &#; The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure.The speed of rotation of the mill influences the power draft through two effects: the value of N and the shift in the center of gravity with speed. The center of gravity first starts to shift to the left as the speed of rotation increases but
