ABSTRACT:
A rotary floor sanding machine has a vertically oriented bell housing with a backside floor support and a dust suction port for removing dust from within. The bell housing encloses the sides and backside of a disk casing and rotary sanding pad. The floor support is configured to place the floor contact area of the sanding pad forward of center. There is a lifting vane extending from proximate the floor contact area of the sanding pad in the direction of rotation towards the suction port in the bell housing to elevate dust particles to the higher velocity airflow near the suction port. There may be a shield for reducing the floor level opening between the back edge of the disk casing and the bell housing.
