A multiple shear mixing apparatus for forming or treating solid-liquid mixtures including a pump selected for handling the solid-liquid mixtures, a rigid shear filter, a jet nozzle, a vacuum chamber surrounding the jet nozzle and having at least one port for introducing materials, a venturi tube coupled with the jet nozzle, a storage tank for the mixture having an internal jet mixer therein, the above components being connected in series such that storage tank contents are pumped through the screen filter, through the jet nozzle, through the chamber and through the venturi tube back to the storage tank. A bleed is fed preferably from between the shear filter and nozzle to drive the internal jet mixer. After cycling through this series of components until uniformly blended, product is withdrawn between the shear filter and nozzle.

[ I claim:] [2.] A multiple shear mixing apparatus for treating a slurry-type solid/liquid mixture, comprising;a storage tank for the mixture;a pump connected to the tank and suitable for pumping said mixture from the storage tank,a shear filter connected to receive the mixture from the pump;a jet nozzle downstream of the shear filter;a venturi tube located to receive mixture from the jet nozzle;a vacuum chamber surrounding the jet nozzle and an inlet end of the venturi tube and having at least one port for the introduction of starting or make-up materials to the chamber;an off-loading outlet for the mixture between said shear filter and said jet nozzle;a jet mixer within the storage tank;the above components being interconnected and adapted to pump said mixture from the tank, through the filter, then through the jet nozzle and chamber, hence into the venturi tube and from the venturi tube into the storage tank, while allowing some of the mixture to be removed from the apparatus through said off-loading outlet.
