Abstract
A mill with an impeller in which blades are mounted between two disks, and each blade has a leading edge projecting into the cross-section of the inlet. The leading edge of every other one of the blades is perpendicular to the axis of the impeller, and the leading edge of the remaining blades on the impeller are skewed. The blades on the impeller alternate in sequence along the circumference of the impeller so that each blade with leading edge perpendicular to the impeller axis is adjacently neighbored on each side with blades having skewed leading edges. The alternative sequence of the blades reduce wear on the blades by a predetermined amount for increasing the operating life of the blades.
