ABSTRACT:
An apparatus for exhausting particulate matter from a bench grinder of the type having a working element which rotates in a circular direction about an axis of rotation for contacting a workpiece, thereby producing particulate matter. The improvement includes a means for creating a current of air which flows past the working element producing a current of air having particulate matter therein. This means also outwardly-exhausts the current of air having the particulate matter therein from the working element along the axis of rotation. A reservoir receives the outwardly-exhausted current and a filter separates the particulate matter from the current of air. Means is provided for exhausting the cleaned current of air.
