Abstract (en)
A sand reclamation apparatus having an air nozzle jetting a blast of air into a reclamation tube (101), and in its passage to pick up resin coated sand grains to spin them and project them into the tube to cause such a scrubbing and abrading multi-collision action of the grains between the interior of the tube and themselves as to remove the coating. The abraded material leaving the tube contacts a target to knock off resin particles which electrostatically cling to the sand grains.
