ABSTRACT:
A machine adapted to be maneuvered across a surface, typically a floor, in order to remove an unwanted coating such as asbestos and adhesive from the floor. An impeller hurls an abradent such as metal shot at an angle against the floor abrading the material which then rebounds along with the abradent up into a return channel where the abradent shot and the abraded material are separated. The shot is returned to the impeller. The abrasion takes place in a downward facing cavity. A wetting spray outside the cavity in advance of the forward end of the machine wets the surface in advance of the abrasion and creates a mist within the cavity which cools the flow of material rebounding from the surface. The presence of the mist greatly abates the dispersion of the abraded material permitting it to be discharged into a collecting drum without contaminating the ambient air.
