ABSTRACT:
A self-cleaning filter includes two cleaning blades spaced from about 75.degree. to about 115.degree. about the circumference of a rotatable tubular filter screen. The tubular filter screen is rotated relative to the two cleaning blades whereby particles in the slurry being filtered having a size less than a predetermined size are forced through the tubular filter screen and particles having a size not less than the predetermined size are removed from the exterior surface of the filter screen and then removed from the filter. The self-cleaning filter is particularly suited for filtering slurries in which solid particles tend to agglomerate.
