  • Patent number: 6921028
    Abstract: Disclosed is a dispersing apparatus comprising a container body; a sealable lid detachable from the container body; a mixing shaft supported by and extending from the lid and having a mixing member; an enclosing member supported by the lid or the mixing shaft and surrounding the mixing member; the enclosing member containing pulverizing media and permitting a pigment-vehicle fluid to pass therethrough; a vacuum pump connected to the lid through a condenser and pipes to reduce the pressure in the container body; and a recovery tank connected to the condenser to collect a liquid fraction separated from a gas fraction by the condenser; wherein the recovery tank and the condenser are connected to the lid through pipes so that the liquid fraction separated by the condenser can be returned from the recovery tank or the condenser to the container body when required, in order to control the viscosity of the pigment-vehicle fluid.
