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.
Claims14
A device for coating solid particles with a coating material which is solid at room temperature comprising:
- a housing;
- a rotatable turbine body mounted within the housing, said rotatable turbine body including a first disk and a second disk which form an annular gap between adjacent surfaces of the first and second disks;
- a first conduit within the housing for delivering a melt of the coating material to the annular gap between the disks and into an annular space in the housing;
- a second conduit within the housing for delivering the solid particles to be coated to a surface of the first disk opposite the annular gap so that the solid particles are spun off into the annular space;
- and
- adjusting means operably connected to the turbine body for adjusting the size of the annular gap between adjacent surfaces of the first and second disks from an outside of the housing.
