The present invention provides a mixing impeller and the like capable of properly performing mixing. A mixing impeller includes multiple blade pairs each having two blades, wherein the blades included in the multiple blade pairs are attached around a rotational shaft extending in a lateral direction, so as to be positioned at a same position in an axial direction of the rotational shaft, the two blades of each blade pair each have a shape that is symmetric about a symmetry plane that is a plane perpendicular to the rotational shaft, the two blades of each blade pair are formed so as to extend from the rotational shaft side toward an outer circumferential side, which is a side opposite to the rotational shaft side, and blade outer portions that are on the outer circumferential side are bent toward a side on which the two blades face each other.

The present disclosure relates to an apparatus for mixing a resin composition for manufacturing a polishing pad including: a raw material mixer preparing a mixed raw material including a prepolymer and a foaming agent; a filter connected to the raw material mixer for filtering the mixed raw material; and a pad composition mixer connected to the filter to prepare a curable mixture including the mixed raw material after being filtered and a curing agent, wherein the raw material mixer includes a plurality of rotators having different rotation speeds.

A method for producing an electrostatic image developing toner includes mixing toner particles containing an amorphous resin with additive particles. A mixing device used in the mixing includes a stirring vessel, a stirring blade, and a jacket configured to cool the stirring vessel, and condition (1) and condition (2) are satisfied. Condition (1): an internal temperature Ti of the mixing device in the mixing and a glass transition temperature Tg of the amorphous resin contained in a near-surface portion of the toner particles satisfy Tg−50° C.≤Ti<Tg (inequality 1). Condition (2): 0.08≤ (Pm−P0)/w≤0.50 (inequality 2) is satisfied. In inequality 2, Pm represents an average power (kW) of a motor for driving the stirring blade of the mixing device in the mixing, P0 represents an idling power (kW) of the motor, and w represents a total mass (kg) of the toner particles and the additive particles in the mixing device.

A mixing assembly and a mixing device configured to mix a bakery, pastry or cosmetic preparation includes a mixing tank configured to receive ingredients intended to be mixed to form the preparation; a first mixing tool configured to be immersed at least partially in the mixing tank and configured to mix the ingredients and/or the preparation. The first mixing tool is configured to be driven in rotation around a first axis of rotation. A second mixing tool is configured to be immersed at least partially in the mixing tank and configured to mix the ingredients and/or the preparation, the second mixing tool being configured to be driven in rotation around a second axis of rotation. The first and second axes of rotation are substantially coaxial.
