Abstract
The process and apparatus for mobile separation and recovery of used abrasive blasting material from a work site. Entrained contaminants within used blast material are removed by a self-contained mobile platform process using multiple stage cleaning system including dual cyclonic separation, multiple stage dust filters with airwash and vibratory separation in a flow through containment and blast media separation process.
Claims5
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.
