An analysis of ball-and-race milling. Part I. The

Abstract The basic principles of mill action were investigated in the batch Hardgrove ball-race machine, modified by the addition of a torque device. It was found that the torque to drive the mill after correction for bearing friction was almost proportional to load M on the balls and independent of rotational speed ω, so that mill power ??? Mω. The first-order specific rates of breakage

2021-4-30 · Ball And Race Mills In this mill the coal passes between the rotating elements again and again until it has been pulverized to desired degree of fineness. The coal is crushed between two moving surfaces, namely, balls and races. The upper stationary race and lower rotating race driven by a worm and gear hold the balls between them.

ball-and-race mills definition English

In order to provide a method for milling ball races and a corresponding side milling cutter which on the one hand also make it possible to produce ball races in ball hubs of VL joints on relatively simpler machining centres and on the other hand also allow the possibility of varying the profile of the ball races produced with one and the same milling cutter, it is proposed according to the

An analysis of ball-and-race milling part III. Scale-up

Mill capacity for race diameter D in meters is where Q H is mill capacity determined by the model for the Hardgrove mill. The total mill power at normal grinding conditions for coal is where η m is motor efficiency. The variations in fineness of grind with mill capacity, Hardgrove Grindability Index, classifier setting, and air—coal ratio are described.

An analysis of ball-and-race milling part II. The

Abstract. A mathematical model was developed for a ball-and-race mill based on specific rates of breakage and primary fragment distributions. The model includes internal classification of particles falling back into the race and external classification due to the built-on classifier. It was demonstrated that the normalized primary fragment
