Abstract
1,084,731. Wet grinding ball mills; agitators. A. SZEGVARI. March 10, 1964 [March 11, 1963; Oct. 2, 1963], Nos. 9599/63 and 38840/ 63. Headings B1C and B2A. An agitator 2, Fig. 2, in an attrition mill for grinding and dispersing materials suspended in liquid in a vessel 3 containing a plurality of attrition elements e.g. balls 1, comprises a central shaft 6 and activators 10 carried on supports 9 projecting from .the shaft. The activators are arranged to set up intense agitation of the media in the presence of the material to be treated while rotating with the agitator and while other portions of the rotating supports moving at different radial distances from the shaft maintain relative quiescence of the media. In operation, scoops at the bottom of the agitator 2 lift the balls 1 from the bottom of the vessel, and the balls are retained by a screen 4. In a further embodiment, the activator supports 21, Fig. 7, are all of the same length and extend at right angles to the shaft in which they are positioned in holes 22 so that one end of each to which an activator 23 is attached projects from the shaft only half as far as the other end. The activators are distributed in the vessel to effect uniform agitation. In a larger vessel activators 31, 33, Fig. 10, may be provided on each support 29 to effect agitation in three cylindricale zones 1. .3. In all the embodiments the leading edge of each support tapers to a knife edge to promote minimum rotation of the attrition elements as a mass. In a further embodiment, flat plates 40, Fig. 14 provide supports for activators 42, 43 which are spaced around a shaft 41 so that no two activators move in the same annular path about the shaft. Where activators are located at different distances from the shaft, those activators which are at the smaller radial distance from the rotational axis may be larger than those at the greater radial distance.
