Abstract

A continuously-operating mixer grinder for foundry sand comprises a pan 3 in which are mounted the grinding devices and mixing devices, a feed hopper 46 which opens near the centre of the pan, at least one ovoid muller mounted with its long axis parallel to a radius of the pan, and at least one peripheral outlet 31 which permits discharge of processed sand and is associated with a deflector device 30 for bringing the peripheral layer of sand into the discharge outlet. As described, the pan rests on wheels, e.g. the wheel 4, each filter with a pneumatic tyre. The wheel axles are each carried on a plate 7 and the wheels are driven by individual motors 11, 12. Three motordriven wheels and further non-driven supporting wheels may be provided. Two ovoid mullers 15,16 are arranged to permit radial sliding movement of the sand beneath them and increasing compression of the sand as it is displaced towards the periphery of the pan. A yoke 21 carries the half axles of the mullers and two half shafts 22, 23 carrying adjustable stirring dishes 24, 25, 26, 27, 28. An additional dish 29 is provided in the shaft 23 to bring back sand from the periphery of the pan towards the centre. The dishs are mounted on vertical rods each inserted in a split collar, e.g. 43, Fig. 3, and orientation of the plane of the disc relative to the shaft is adjusted by the nut 44 and bolt 45. Tramp material in the pan causes the disc to be lifted by rotating a loose ring 36 in opposition to a spring 37 which then returns the disc. The initial angular keying of the loose ring relative to the shaft may be adjusted by a screw 40.
