Blast cleaning wet media feed and separation system

Abstract From the Canadian patent

A media particle size separating apparatus arid method are disclosed for use with a slurry blast cabinet. The system is capable of continuous operation so that under sized blast media particles and fines can be separated out of the slurry along with debris from the blasting operation on a continuous basis. An upwardly open partition divided hopper receives spent slurry from the blasting cabinet to flow through at least two chambers in the hopper to a pump returning the slurry and sized media to the blasting cabinet and nozzles therein. Unusable fines collected in one chamber of the hopper are drawn off through a drain valve.
