Reclaiming system for foundry sand SEARS; EDWARD A.
A reclaiming system for used foundry sand containing a sodium silicate (water glass) binder. The resulting chunks of sand and binder are disintegrated by mechanical crushing in a water wash. A primary slurry containing discrete particles of sand and both dissolved and suspended binder is conveyed to a settling tank where the sand settles from the slurry.
Process of reclaiming used foundry sand Kenzler
Used foundry sand is reclaimed by crushing the sand and separating both metallic material and at least a portion of the unwanted non-metallic portion of the sand, then heating the sand to a temperature of about 1400° F. for burning off the foreign material and causing the sand particles to pass through a strong expansion phase somewhere above 1000° F. and passing through a
