A system and method are disclosed for mixing a suspension. The suspension may optionally have a low liquid viscosity. The suspension may, optionally, include a metallurgy solvent extraction (SX) mixture. The system and method may be at an industrial scale. In some embodiments, suspension may be stirred at high energy dissipation rate with a large impeller. The system may optionally include baffles. The impellor and/or the baffles may optionally include a rounded edge. The method may be applied to retrofitting a SX plant. The input feed to a mixing reactor may include an emulsion and/or multiple discrete phases.

A method of producing particles by bringing plural dissimilar materials A and B into contact with each other includes feeding a liquid into a reactor from a first end portion of the reactor such that the liquid flows along the inner peripheral surface of the reactor and generating a vortex flow toward a second end portion in the reactor by the feed of the liquid; disposing a flow-assisting blade capable of rotating around the central axis line in the reactor and rotating the flow-assisting blade; and injecting materials to be contacted A and B into the reactor, discharging a contacted liquid from the second end portion of the reactor, and generating the particles in the contacted liquid.

The processing machine (1) is adapted to carry a processing tool driven by a motor and includes a safety shield (4) adapted to at least partly shield the processing tool in relation to a user. The safety shield (4) is arranged displaceably away from its shielding position and a magnetically activatable safety arrangement (14) includes a safety switch (15) being operable between a passive state in which the motor (2) is allowed to operate and an activated state in which the motor is prevented from operation. The safety switch (15) is arranged to switch from its passive state to its activated state when the safety shield (4) is displaced away from its shielding position. At least one magnet (16) is arranged to hold said displaceable safety shield (4) in its shielding position and at the same time hold the safety switch (15) in its passive state.

Disclosed is a device and a method for processing plastic material with at least one receiving container, wherein at least one mixing and/or comminution tool, rotatable about a rotation axis, is arranged, for mixing and warming the plastic material, and with at least one conveyor for discharging the plastic material from the receiving container, with at least one screw rotating in a housing, where the conveyor is connected, at its material inlet side via an opening which is formed in a side wall of the receiving container, with the interior of the receiving container. An imaginary extension of the central longitudinal axis of the conveyor extends, against the conveyance direction of the conveyor, past the rotation axis of the receiving container, without intersecting this axis, where the longitudinal axis of the conveyor is offset by a separation relative to the radial ray of the receiving container on the discharge side.

A mixer is disclosed including a sealed mixing chamber having an interior, and a rotating mixing bowl within the interior of the sealed mixing chamber. A stand operatively supports the sealed mixing chamber. The stand includes: a foundation, a mixing chamber base movably coupled to the foundation and positioning the sealed mixing chamber at an angle relative to horizontal, and a linear actuator system configured to move the mixing chamber base relative to the foundation in at least one linear direction. A rotating mixing head is operatively positioned and sealingly disposed within the sealed mixing chamber, the rotating mixing head rotating within the rotating mixing bowl. The mixer and a related method provide for ceramic suspension mixing with reduced cooling and possibly without cooling the suspension.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

A seed treatment method, using a composition obtained extemporaneously by mixing at least one powder substance and an aqueous medium, comprising the steps consisting of: producing the mixture in an automatic and cyclic manner, in at least one first vessel (10; 10), by introducing into same first at least a portion of the aqueous medium and next the powder substance, the latter being sucked into the aqueous medium in the vessel by means of a vacuum created in the vessel, at least partially draining the content of the vessel, by means of at least one blast of compressed gas in the vessel, to a seed treatment device where the mixture is brought into contact with the seeds.

A device for mixing powders by cryogenic fluid, characterised in that it comprises at least: a chamber for mixing powders, comprising a cryogenic fluid; a chamber for supplying powders in order to allow the powders to be introduced into the mixing chamber; means for agitation in the mixing chamber so as to allow the mixing of the powders placed in suspension in the cryogenic fluid.
