Abstract

139,511. Fuller-Lehigh Co., (Assignees of Fuller, J. W.). Aug. 27, 1917, [Convention date]. Ball-and-ring mills.-Relates to pulverizing-mills of the type described in Specification 24393/07, the example shown comprising a rotatable member 32 formed with four radial arms 42 which are provided with pushers 44 for the balls 31, the member being also provided with a ring 36 to which are secured scoops 38 and blades 41, adapted to lift the pulverized material and force it through a screen 14 respectively. According to the invention, free rolling movement of the balls about any diameter is attained by shaping the surface of the fixed grinding-ring 24 to a greater radius than that of the balls, and by supporting the balls freely upon an annular bearing-surface on a carrier 30 rotating within the ring 24, this bearing-surface being also shaped to permit free movement of the balls. Further, alternate pushers 44 are replaced by lifting-devices 46 consisting of a curved scoop 48 and a hollow body 47 and detachably mounted by pins or bolts 43 on the outer ends of the radial arms 42. The mill can be adapted for coarse-grinding or fine-grinding by giving such a shape and inclination to the scoops that the pulverized material is deflected towards the periphery or the axis of the screen 14 respectively.
