ABSTRACT:
A surface blasting apparatus including a wheel mounted chassis carrying a detachably mounted blasting head assembly. The blasting head assembly includes a housing enclosing a blasting wheel mounted for rotation about an axis extending parallel to a surface to be cleaned. The housing further includes a return chute through which abrasive returns after impacting such surface. A baffle assembly and magnetic arresting assembly cooperate to clean the abrasive particles by air washing. The air is then directed through a gravitating curtain of abrasive particles at a second cleaning location for further cleaning. The dust and debris laden air is then passed through a cyclonic separator and filtering system to clean the air prior to atmospheric discharge. Variously sized blasting head assemblies can be interchangeably mounted on the chassis for accomplishing various types of blast cleaning operations.
