The present invention relates to a granulating and/or agglomerating tool for a granulating and/or agglomerating device with a fastening shaft and a substantially disk-shaped element with a diameter d which is fastened thereto and has an upper surface, a lower surface and a circumferential surface connecting the upper and the lower surface. In order to provide a granulating and/or agglomerating tool for a granulating and/or agglomerating device and a corresponding granulating and/or agglomerating device and a method for granulating or agglomerating with which the desired granulating or agglomerating result can be obtained very much faster and above all with a significantly finer granulated material with a significantly higher yield in the range of from 0.1 to 0.8 mm, it is proposed according to the invention that the circumferential surface exhibits a plurality of essentially V-shaped grooves running parallel to the axis of the shaft.

A device for granulation of concentrated and/or aqueous solutions/melts may include a shaft extending in a longitudinal direction and rotatably mounted within a housing. Impact arms may extend radially outward from a rotation axis of the shaft. Due to blade elements attached to the impact arms, particles of fluidized material to be treated may advance in the longitudinal direction along a flow direction and be rotated and mixed by the blade elements. A first blade element may have an attitude so as to be inclined relative to a plane that in a transverse direction extends through the rotation axis, when viewed in the conveying direction. A second blade element may have an attitude that is counter to the flow direction such that the second blade element when viewed in the conveying direction is aligned so as to be reversely inclined relative to a remainder of the blade elements.

A manufacturing method for a granulated body includes supplying powder agitated by a dry agitator to a wet agitator, and agitating the powder supplied from the dry agitator with a liquid component in the wet agitator by rotating blades that have inclined surfaces, so as to form a granulated body. The blades are rotated when the powder is supplied to the wet agitator from the dry agitator. The dry agitator agitates the powder in a dry state, and the wet agitator is positioned below the dry agitator. The wet agitator includes an agitation chamber and the blades rotating around a center axis orthogonal to a direction in which the powder is supplied.

A granulated material is provided which enables a reduction in the amount of adhesion of the granulated material to a conveyor junction.

A granulated material includes sludge in an amount of greater than 30 mass % and 90 mass % or less and sintered ore powder in an amount of 10 mass % or greater and less than 70 mass %. The granulated material includes granulated particles in which at least a portion of the sludge adheres to at least a portion of the sintered ore powder.

Disclosed are a particulate processed product of tea and a method for preparing the same. The particulate processed product of tea has a sphericity S.sub.10 value of a particle corresponding to 10% cumulative subdistribution in cumulative distribution measured for the sphericity of tea particles of 0.68 or greater. The processed product of tea is convenient to drink because it is readily wetted and dispersed in water. In addition, it can be easily packaged and used due to a low angle of repose and thus excellent flowability.

A dry stirrer configured to stir powder in a dry state, and a wet stirrer provided downward of the dry stirrer in the vertical direction and configured to stir the powder are used. In the wet stirrer, the powder is stirred together with a fluid component, so that granules are formed. The wet stirrer includes a stirring chamber having a cylindrical shape and having a central axis placed in the lateral direction, a cut blade configured to rotate around the central axis of the cylindrical shape in the stirring chamber, and an agitating blade configured to rotate along an inner wall that is a cylindrical side face inside the stirring chamber. When the agitating blade passes above the central axis of the stirring chamber in the vertical direction, the agitating blade is rocked.
