Abstract
298,396. Bell, W. J. Nov. 24, 1927. Pneicmatic separating.-Used foundry sand is renovated by the action of an air current, a brushing device, and a screen and by adding other ingredients. The sand is carried by belt and bucket conveyers 1, 7 to an aerator 11 which comprises a rotating drum 50, Fig. 2, with pins 51 co-operating with an oscillating brush 55. The sand from the aerator falls on to an inclined screen 12 jarred by a cam 14 so that unbroken lumps &c. fall to the bottom of the conveyer 7 or if such material is excessive it can be withdrawn by opening a valve, not shown, in the top of a conduit 19. During the whole of this process the sand is cooled by a current of air, produced by a fan 60 and regulated by a valve 62, which also removes dust and fine sand.
