Abstract
A rotary filter apparatus includes a tank for containing a slurry to be filtered. A rotary drum is mounted for rotation about a horizontal axis. The drum has a filter surface which extends into the slurry, so that the filtrate may be withdrawn from the interior of the drum. An agitator in the bottom of the tank includes a vane mounted below the drum for rotation about a horizontal axis. The vane is driven to reciprocate through a driven angle about its rotational axis.
