Abstract:
1. A process for separation and recovery of contaminated abrasive blasting material wherein said process comprises the steps of, a. transferring contaminated abrasive blast material to a mobile self-contained separation recovering and reuse supply apparatus, b. separating airborne contaminants within said contaminated abrasive blast material by a first cyclonic air separator, c. separating airborne contaminants by a second cyclonic separator in communication with said first cyclonic air separator, d. transferring said airborne contaminants from said second cyclonic air separator to a high pressure dust filter media, e. separating contaminants from said blast material from said first cyclonic air separator by a vibratory screen separator and specific gravity, f. transporting said abrasive blast material separated by said vibratory screen to an airwash specific gravity separator, g. transporting air entrained contaminants from said airwash separator to a low pressure dust filter medium, h. transferring clean abrasive blast material from said airwash separator into a holding and distribution recycling reuse bin, i. purging said high and low pressure dust filter media by compressed air.
