A method and apparatus are defined for coating a particulate material. The apparatus includes a mixer having a mixing chamber. A quantity of particulate material is fed into an inlet of the mixing chamber. An agitator is provided for mixing and conveying the particulate material. A feed system is also provided for delivery of a coating into the mixing chamber. The coating is delivered as an atomized spray directed at the mixing particulate material within the mixing chamber. A controller is provided for adjusting the flow of the coating into the mixing chamber based on the volumetric feed rate of the particulate material.

The following are performed in stated order inside of a granulation tank including two or more agitators having different stirring axes to one another: (i) stirring a powder material containing an electrode active material to place the powder material in a stirred state; (ii) adding a composition containing a binder and a solvent to the powder material in the stirred state to obtain pre-composite particles; and (iii) stirring the pre-composite particles after addition of the composition is complete to perform particle adjustment and obtain composite particles.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a vacuum port in an upper portion of the chamber, a chemical delivery system configured to inject a reactant or precursor gas into a lower portion of the chamber, a paddle assembly, and a motor to rotate a drive shaft of the paddle assembly. The lower portion of the chamber forms a half-cylinder. The paddle assembly includes a rotatable drive shaft extending through the chamber along the axial axis of the half cylinder, and a plurality of paddles extending radially from the drive shaft such that rotation of the drive shaft by the motor orbits the plurality of paddles about the drive shaft.

A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

A clumpable animal litter comprises composite particles of filler materials, such as limestone and sand, and sodium bentonite. The filler materials have a lower bulk density as compared to a granular mixture of the same percentage of filler and sodium bentonite clay and contain up to eighty-five percent less clay.

A granulated body manufacturing apparatus includes: a housing that includes a cylindrical internal space, is disposed so that a center axis direction of the internal space is horizontal, and houses a raw material for a granulated body inside the internal space; an agitation blade that is provided along an inner circumferential surface of the internal space, and upon being rotated around the center axis, scoops up the raw material accumulated in a bottom portion of the internal space and makes the raw material fall down from an upper position inside the internal space; and a crossing blade including a wire having a wire diameter not exceeding 0.3 mm, the wire being provided at a position in a range, inside the internal space, in which the crossing blade does not come into contact with the agitation blade, and being looped around a framework body that rotates around the center axis.

Provided is a continuous reaction apparatus which can precisely control the path of flow of the liquid reaction mixture in the reaction vessel. Further, provided is a continuous reaction apparatus which can efficiently mix the liquid reaction mixture in the reaction vessel. The continuous reaction apparatus comprises a plurality of mixing vessel units and a plurality of partition units. These units are connected in the state of being alternately stacked on one another. Each mixing vessel unit has an agitating blade disposed in the inner space thereof. The relationship between the inner diameter D1 of the mixing vessel unit, the height H of the mixing vessel unit, and the outer diameter d1 of the agitating blade satisfies the formula (1): 10(D1/H)1.5, and the formula (2): 0.99(d1/D1)0.7. The agitating blade is a circular disc-type agitating blade.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a chemical delivery system, and a paddle assembly. The paddle assembly includes a rotatable drive shaft and a first plurality of paddles and a second plurality of paddles that extend radially from the drive shaft. The spacing, cross-sections, and oblique angles of the paddles are such that orbiting of the paddles causes the first plurality of paddles and the second plurality of paddles to displace substantially equal volumes in opposite directions in the lower portion of the stationary vacuum chamber.
