Abstract

1535093 Reclaiming foundry sand A VALSECCHI 25 May 1976 [9 June 1975] 21513/76 Heading B3G Lumps of foundry mould sand are fed at 18 into a rotary drum 12 supported by framework 10 and driven by a motor 11, and are broken up by chains 13, 13<SP>1</SP> attached to the drum end walls. Sand passes from the innermost perforated wall of the drum through a surrounding screen 14 into an annular space 17 bounded by a screen 16; material such as steel chips in the space 17 effect cleaning of the sand which passes through the screen 16 into a space 29 containing quartz or silica grains which complete the sand cleaning process. Sand then passes through a perforated wall 28 and hopper 21 to a reciprocating shoot containing a grid 22 through which the finer sand passes. A suction fan 27 exhausts powders obtained during the sand treatment.
