Abstract
A device is disclosed for improved coating of small solid particles with a melt of a material which solidifies at room temperature. The device includes a rotatable turbine body having two rotatable disk parts. An annular gap is provided between the rotatable disk parts which allows the melt to emerge to coat the solid particles in an annular space. The two rotatable disk parts are connected by a fine-pitch thread which allows the size of the annular gap to be adjusted by rotating one of the disks relative to the other. Rotation of one of the disks is performed from the exterior of the device by an adjusting pin which eliminates the need to dismantle the device to adjust the flow of the coating material.
