ABSTRACT:
A riding floor sander for large hardwood floor surfaces, such as gymnasiums and dance floors, has a powered cart with one or more sanding machines connected to it. A blower picks up the process waste in a stream of air and and moves it to a cyclone separator that is mounted on the riding sanding machine. There the dust is separated from the air stream, leaving clean air to be returned to the ambient. The dust that falls from the cyclone into a dust collection drum or bag on the cart. There can be are primary cyclonic separators on the sanding machines, and a cyclonic separator on the back of the riding cart. Alternatively, the cyclone and drum may be located remote from the riding sander, and can have an in-line auxiliary pump or impeller.
