Apparatus for dispersing finely divided solid particles in a liquid vehicle

In apparatus for deagglomerating and dispersing solid particles held in agglomerated form and carried in a liquid vehicle while in a mixing vessel in which the particles are subjected to the action of a dispersing media while being forced to flow through the interior of the vessel and subjected to a contrifugal and agitating action therein which causes the dispersing media to be thrown outwardly and separated from the flow path of the product of liquid mixture being processed;

• a rotatable shaft extending into said vessel and adapted to be driven from a power source;
• a dispersing media separator located interiorly of the mixing vessel so as to be positioned in said flow path and having means for the admission of the processed product thereinto and therethrough so that the product is forced to travel through said dispersing media separator in a direction opposite to that generated by the normal centrifugal force;
• said separator comprising a body surrounding and attached to said shaft and rotatable therewith;
• means defining inlet and outlet means to and from said separator, said separator outlet means being in fluid communication with said vessel outlet;
• a flexible filter screen of sheet material surrounding and lying against the outer surface of said body;
• coil spring means surrounding and lying against said filter screen to secure said filter screen to said body;
• and
• means for detachably securing said coil spring means in place around said body.
