A stirring apparatus includes a shredder that shreds a sheet; a case that accommodates a sheet piece shredded by the shredder and has a bottom surface and an inner surface; and a rotator that is disposed at the bottom surface of the case and includes a blade which stirs the sheet piece by rotation, in which L1<L3<L2, when between an outer end of the blade and the inner surface in a radial direction of the rotator, a shortest distance in the radial direction is defined as L1, a longest distance in the radial direction is defined as L2, and an average major axis length of the sheet piece is defined as L3.

A mixing vessel for accommodating components to be mixed has a container with at least one mounting depression in a side wall of the container. The mounting depression is adapted so that a mixing impeller housing of a mixing impeller is at least partly insertable, in which at least one magnet is housed for being magnetically connectable to a drive device to be driven. A locking assembly is attachable to the mounting depression from outside for locking the mixing impeller in a storage position, in which the mixing impeller is not rotatable. The locking assembly has a magnetically active element that is adapted to interact with the magnet of the mixing impeller.

A test device having a micro flow channel including a reaction part where a reactant that is reactive to a tested chemical dispersed in a tested fluid is fixed, and at least one actuator for actuating the tested fluid to move in at least one of two opposite sides of the micro flow channel so as to homogenize a density distribution of the tested chemical in the tested fluid. The tested fluid is sent in the micro flow channel a plurality of times.

A high shear liquid metal treatment device for treating metal includes a barrel, a rotor shaft, rotor fans, and stator plates. The barrel has a longitudinal axis that extends between an upper end and a lower end, and an opening at its upper and lower ends. The rotor shaft is mounted centrally through, and parallel to the longitudinal axis. The rotor fans are mounted along an axial length of the shaft. The stator plates are formed on an inner surface of the barrel and are located between adjacent rotor fans. Each stator plate has at least one passage formed therethrough to allow fluid to pass through the plate; and upper and lower surfaces of each stator plate are formed to be within the minimum distance of an adjacent rotor fan. The minimum distance is between 10 μm and 10 mm. The device allows improved treatment of liquid and semi-liquid metals during processing.

Embodiments of the present disclosure involve methods, devices, and systems for hydrating polymers using multiple mixing chambers. Adjacent mixing chambers may be coupled using an under-over baffle, and each mixing chamber may be generally rectangular with rounded corners.

A container includes a blending base, an internal wall surface, and an internal bottom surface. The blending base is formed inside the container, extending upward slantwise from a peripheral edge of the internal bottom surface to the internal wall surface. The blending base includes a plurality of turning portions and extended curves at a top edge thereof. The extended curves are linked with the turning portions and cling to the internal wall surface. Thus, the blending base does not adversely affect the appearance of the container and can enhance the blending effect. In addition, the container can be washed and cleaned easily due to the blending base.

The invention provides a method for preparing graphene which method comprises the steps of: (a) forming a graphite/water mixture; and (b) introducing the graphite/water mixture into a cavitation reactor using at least two offset nozzles; a cavitation reactor for use in the method wherein the cavitation reactor has a cavitation chamber wherein the cavitation chamber has at least two offset inlet nozzles which are directed towards the centre of the cavitation chamber and at least one outlet; and graphene having a carbon content of at least about 98 wt %.

Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.
