Date Mar. 16, 1995A 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 and conduits for supplying solid particles and molten material to the rotatable turbine body. The turbine body is rotated by a hollow drive shaft and is provided with a series of heating conduits extending through the drive shaft and the turbine body for heating the turbine body. The turbine body can be heated to a controlled temperature to maintain the molten material at a desired temperature by varying the temperature of a heating agent which is supplied through the heating conduits.</p> |
