ABSTRACT:
The dynamic pressure filter is constructed with a plurality of coaxially disposed rotor sectors and stator sectors. Filter surfaces are mounted on each of the sectors to define annular filter chambers for receiving a suspension to be filtered under pressure. In addition, vortex breakers are provided at the downstream end of each filter chamber for destroying the flow structure of the suspension prior to flow into the downstream filter chamber.
