Abstract

172,221. Lake, W. B. Dec. 6,1920. Treating mould and core materials.-Used sand, particularly facing sand for steel castings, mixed with a small quantity of fresh sand is sifted from a dryer a to a pipe g along which it is blown by compressed air, the friction between the particles serving to detach the silica from the lighter matter, which is blown past baffles k and passes to a settling-chamber n. The silica checked by the baffles falls down into buckets q, which serve to measure it and pass it into a mill r, where the requisite quantity of clay and water are added.
