Abstract

1,37,221. Cement mixers. BENFORD Ltd. May 2,1963 [May 9,1962], No. 17742/62. Heading B1C. In a pan-type mixer having mixing blades which revolve about a vertical axis in an orbit round the pan, depending from overhead arms and being mounted so that they can rise to pass over obstructions such as large stones, the blades are arranged so that the resultant of their weight and the thrust of the material on them urges them downwardly to the normal operating position. As shown the blades 79 are carried on arms 16 freely pivoted about axes 71; the rise and fall of the arms 16 is limited by stops 96,97. The axes 71b, 71d lie in radii of the pan; the remainder are arranged so that the outer ends lag relative to the direction of rotation (which is clockwise in Fig. 1) and the arms 16 are variously shaped so that the mixing blades sweep different annular zones. The mixing blades, see Fig. 4 (not shown) are trapezoidal and have working faces consisting of two inclined surfaces; they are secured to a plate mounted on the end of arms 16 by means of bolts passing through slots at right-angles in the blade and mounting plate so that the blade is adjustable in any direction, and rubber pad being placed between the blade and plate. The pivot bearings of the arms 16 may be of polytetrafluoroethylene, or may be of plain steel and lubricated by molybdenum disulphide, or may be flexible bushes. The line of action of the reaction of the material on the blade preferably passes above the pivot, though it may pass below the pivot if its movement thereabout is less than that of the weight of the arm and blade. The arms 16 are carried on a head 18 rotated by a motor 23, gearbox 25, and gearing 24, 26 operating in an oil bath 42. The arms may be weighted by a detachable casing, see Fig. 3 (not shown). There may be a resiliently-mounted scraper blade 100. The mixing pan 10 may be annular as shown, or cylindrical; the bottom 14 and inner wall 12 are provided with wear plates. A lenticular discharge door in the bottom of the pan is pivoted at 108 and operated by a pneumatic jack 112.
