An impeller assembly for a solid-liquid mixing device, which includes an impeller body, multiple mixing blades which are evenly distributed on the inner side of the impeller body and extended outwards from the shaft of the impeller body, and at least two baffle plates being disposed on the outer side of the impeller body along a radial direction thereof outwards and disposed in the circumferential direction of the impeller body. At least one pair of adjacent two baffle plates satisfies following conditions: curves projected by two opposite surfaces of each of adjacent baffle plates on a cross section of the impeller at any height are smooth curves, and at least one of the curves is not fully included in a circle with the center of the shaft as its center.

Coned augers for bulk mixers are described. The coned augers comprise first end and second end an auger post having a first end opposite a second end; fighting extending along and about the auger post, the pitch oriented to move bulk material generally from the first end toward the second end during operation of the auger; a coned section along the auger post, the coned section comprising a first cone protruding about the periphery of the auger post, the first cone having a tapered end opposite a wide end. Mixers comprising the coned augers are also described.

An impeller assembly for a solid-liquid mixing device, and a solid-liquid mixing device using the impeller assembly. The impeller assembly comprises an impeller. The impeller comprises a truncated conical body. Multiple mixing blades are formed from top to bottom on an inclined surface of the body. The impeller assembly further comprises at least one blocking plate provided on an outer side of a lower portion of the body. The mixing device further comprises: a housing; at least one solid supply apparatus; at least one liquid supply apparatus; a mixing chamber defined by corresponding portions of the body and the housing; and a dispersion chamber provided between a flow channel outlet at a lower portion of the mixing chamber and a discharging apparatus.

A metering system for applying a bead of a multi-component composite material to a component. The metering system comprises a mixing head including a mixing chamber. The metering system includes one supply line for each component of a multi-component composite material, leading from a source of each component to the mixing chamber. The mixing chamber is configured to mix the components of the multi-component composite material in the mixing chamber and has an outlet opening through which the mixed multi-component composite material exits the mixing head. The metering system includes a metering pump to convey a discharge of the multi-component composite material through the outlet opening. The metering system includes a control unit to output, to the metering pump, a control signal comprising control information and adjust a metering output of the multi-component composite material through the outlet opening of the mixing head based on the control signal.
