ABSTRACT:
A filter is described for separating solid particles and breaking down dense masses from a liquid carrier, and for promoting mixing of friable, dry material with the liquid. The filter comprises a housing having an interior wall of substantially circular cross-sectional configuration. A cylindrical filter member is carried inside the housing but is spaced apart from the housing interior wall. A circular fluid flow path is thus defined between the wall and the filter member. A liquid outlet port is defined in the housing and communicates with the inside of the filter member. A liquid inlet port is oriented so as to direct the fluid flow over and past the filter so as to cause an extending filtering and filter-cleaning action.
