The present invention is related to an installation and to a method for recirculating and mixing a fluid which is preferably a shear-thinning fluid. The installation comprises a tank, a pump, a piping assembly connected to the pump and comprising an injection piping for injecting said fluid into the tank and a return piping coupled to the injection piping for pumping the said fluid from the tank to the injection piping, wherein the piping assembly and the tank form a flow recirculation path in which fluid is homogenized by recirculation of the fluid upon action of the said pump, the injection piping being designed such as to reinject the fluid in at least two peripheral bottom locations with an horizontal and/or inclined orientation such as to create a swirl movement in the tank and to reinject simultaneously said fluid upwardly through a central location in a zone comprised between the central axis of the tank and the half radius of the tank such as to create a jet of fluid having a main vertical component.

A process is shown for manufacturing a milk of lime of great fineness which includes at least the steps of providing one lime compound chosen in the group consisting of prehydrated lime, a paste of lime obtained by addition of water to quicklime instead of addition of quicklime to water and their mixture, and forming a milk of slaked lime of great fineness with the chosen lime compound. The paste of lime is obtained by progressive addition of water to quicklime under agitation conditions.
