Provided is a method of producing a catalyst-bearing support that produces a catalyst-bearing support used in production of a fibrous carbon nanostructure. The production method includes: a stirring step of rotating an approximately circular tube-shaped rotary drum around a central axis so as to stir a particulate support; a spraying step of spraying a catalyst solution against the particulate support inside of the rotary drum; and a drying step causing a drying gas to flow to inside of the rotary drum from outside of the rotary drum so as to dry catalyst solution attached to the particulate support. In this production method, at least part of an implementation period of the stirring step and at least part of an implementation period of the spraying step overlap with each other.

A system for coating fertilizer substrates is provided. The system comprises a mixing unit wherein the mixing unit comprises a container bowl having an inlet portion and an outlet portion wherein the inlet portion is operatively fastened to a hot air conduit having a blowing unit connected at one end. The invention also relates to a process for coating fertilizer substrates and the coated substrates thereof.

The invention provides a sintered rare earth metal oxide target for producing a radioisotope in an instrumentation tube of a nuclear power reactor, wherein the sintered target has a density of at least 90 percent of the theoretical density, and wherein the sintered target contains chromium in an amount of from 500 to 2000 μg/g, and Mg and/or Ca in an amount of from 1000 to 6000 μg/g. The sintered target is prepared by providing a rare earth metal oxide powder, blending the rare earth metal oxide powder with chromium oxide, dry granulating and consolidating the powder in a mold to form a spheroidal green body, and sintering the green body in solid phase to form a spheroidal ytterbia target.

A drum coater for applying a surface layer on bulk-like materials includes a rotatably mounted drum for accommodating bulk-like materials, inlet and outlet openings, at least one spray nozzle for applying the surface material, a drying device for a drum interior, at least first and second radially-offset mixing tools in the drum, the first mixing tool protruding into the drum interior. The at least one second mixing tool has at least one mixing surface such that the first mixing tool is at least partially arranged on the drum inner surface and the at least one second mixing tool has at least one opening on the at least one mixing surface. A mixing tool to be used in a drum coater to gently blend and/or homogenize bulk-like materials has a first mixing surface angled relative to a second mixing surface, at least one mixing surface having at least one opening.

The present disclosure relates to a method for controlling the temperature in a granulator in which a melt of an hydrous nitrate mineral salt-based composition is granulated. The method comprises the steps of granulating the melt, separating out the undersized and oversized particles at the outlet of the granulator and recycling the undersized and oversized particles to the granulator, measuring the temperature in the granulator, adjusting the amounts of undersized and oversized particles recycled to the granulator according to the measured temperature in the granulator. The present disclosure further relates to low dust producing uncoated granules of a hydrous nitrate mineral salt-based composition.

Shown 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.
