The Cavex hydrocyclone design delivers maximum efficiency maximum hydraulic capacity and long wear life The laminar spiral inlet geometry design provides a natural flow path into the Cavex hydrocyclone Its unique shape has no sharp edges or square corners and allows the feed stream to blend smoothly with rotating slurry inside the chamberoperational and furnish quality parameters on the state of operation is missing As separation selectivity is cl osely dependent on thic kening and pulp passage an operation curve for separation was applied and its application further developed to examine the parameters affecting pressure screen and hydrocyclone separation
