A cold water saponification method is disclosed. The method is for preferred use in industrial applications such as mining operations wherein saponification of fatty acids is required. Broadly, the method comprises the steps of filling a tank with a solution comprising water, a base and fatty acids, installing a mixer capable of creating a vortex in order to effectively saponify fatty acid particles. The use of a high-shear mixer installed vertically has been proven successful in saponifying fatty acids in cold water.

A device for dispersing a water-soluble polymer includes a primary water inlet circuit that feeds an overflow, at the bottom end of the cone, an assembly including a chamber for grinding and draining the dispersed polymer, having a rotor driven by a motor provided with knives, a stator, over all or part of the periphery of the chamber, a ring fed by a secondary water circuit, the ring communicating with the chamber by way of slots for spraying pressurized water onto the stator The slots of the stator and/or the knives of the rotor are tilted at an angle of between 20 and 80 relative to the horizontal plane of the stator and the lateral face of the blade next to the stator is curved in such a way as to make the distance separating the two components substantially constant.

A technique facilitates mixing of cement slurry for use in a cementing application. At least one cement mixer is provided with a tank, e.g. a conical tank, having a powder cement blend inlet and a mixing liquid inlet. A cement slurry discharge may be positioned generally beneath the tank. A mixing assembly also is positioned below the tank and driven by a shaft. The mixing assembly is exposed to an interior of the tank and is used to mix the cement slurry when rotated by the shaft and to direct the cement slurry out through the cement slurry discharge. Additionally, a recirculation system comprises an inlet positioned to receive a portion of the cement slurry mixed in the mixing assembly. The recirculation system also comprises an outlet positioned to direct the portion back into the mixer to enhance mixing effects.

A rotor-stator system for agglomerate mixing apparatus utilizes a unique rotor-stator mixer assembly which combines a high efficiency rotor with unique stator element designs to address the limitations of prior rotor-stator mixer assemblies, including the dispersal of large agglomerate and problem of heat build-up. The stator elements have a variety of slot openings in different sizes and shapes whose inside walls are slanted in an acute attack angle that will generate circumferential, rather than exit flow. These slot configurations enable rapid large agglomerate reduction into smaller and smaller agglomerates and ultimately down to particle size without the need to change stator configuration, which is already built into the device.

The problem of providing a stirrer capable of more effectively shearing a fluid to be treated is addressed, by using the action of an intermittent jet stream. A stirrer is provided with a rotor having a blade and a screen, which are relatively rotated such that the fluid to be treated is discharged from the inside of the screen to the outside as an intermittent jet stream through a slit in the screen, the stirrer satisfying condition 1 and condition 2. (Condition 1) the relationship among the width b in the rotating direction of a tip part of the blade, the width s in the circumferential direction of the slit, and the width t in the circumferential direction of the screen member is b2s+t. (Condition 2) the relationship between the width b in the rotating direction of the tip part of the blade and the maximum inner diameter c of the screen is b0.1c.

A mixing unit comprising a frame, a rheology control portion, and a high-volume solids blending portion. The rheology control portion comprises means for receiving a first material from a first transfer mechanism, a dispersing/mixing system connected with the frame, and a first metering system to meter the first material from the first material receiving means to the dispersing/mixing system. The dispersing/mixing system disperses/mixes the metered first material with a fluid to form a first fluid mixture. The high-volume solids blending portion comprises means for receiving a second material from a second transfer mechanism, a solids blending system connected with the frame, and a second metering system to meter the second material from the second material receiving means to the solids blending system. The solids blending system blends the metered second material with the first fluid mixture to form a second fluid mixture.

An object of the present invention is to develop a mechanism capable of more effectively performing processing such as emulsification, dispersion, dissolution, atomization, mixing, or stirring on a processing object with fluidity using an atomization device including a rotor-stator type mixer while an inside of a processing tank is maintained in a pressured state, at atmospheric pressure, or in a vacuum state, and occurrence of a negative pressure state on a center side (inner diameter side) of a rotor is actively suppressed or prevented.
