Propelled by air, sand is accelerated at a controlled rate up through a blast tube to a conical target. The Pro-Claim tubes typically require minimal maintenance. When maintenance is required, the Pro-Claim's design makes the blast tubes easy to remove and the target easily accessible through an outside door. Sand accelerated through the blast tubes is scrubbed against sand trapped under the conical target. As the sand curtain falls from the target area, it is immediately exposed to exhaust air drawn through a shroud surrounding the target.
Residual binder is scrubbed off the sand grains and excess fines are removed.
This controls Loss on Ignition and maintains the original screen distribution. Part of the sand is recirculated into the same cell, and part is diverted to the next cell by means of adjustable deflector plates. This adjustment controls retention time and determines the degree of cleanliness of the reclaimed sand. The reclamation process is repeated through as many successive cells as needed, depending on your specific sand conditions and requirements for sand cleanliness. When the sand emerges from the last cell, excess fines are removed in a final dedusting chute.
