Ball tube mill

摘要

A ball tube mill has a housing with an inlet and an outlet for material to be comminuted accommodates annular wall plates spaced at a predetermined distance from each other, arranged at an angle to the longitudinal axis of the housing, and having the form of an ellipse. The space between the adjacent annular wall plates is somewhat greater than D/tan alpha , where D is the inside diameter of the housing, and alpha is the inclination angle of the annular wall plate to the longitudinal axis of the housing.
