ABSTRACT:
An apparatus used for coating particles has a vessel in which a rotor which can be rotated about a vertical axis and possesses a disk. During coating of particles, the particles rest on the disk and are moved by the latter as a result of rotation, a process gas also being passed upward through an annular gap present between the wall of the vessel and the disk. The apparatus has at least one atomizing member which projects into the particle bed present on the disk. A coating material which is solid at room temperature is melted at least for the major part, sprayed by means of the atomizing member in the interior of the particle bed and onto the particles, and solidified by cooling. Pore-free and smooth coatings can be applied in this manner.
