Abstract:
1. An apparatus for producing substantially spherical polymorphic particulates comprising: a cyclone containing a fan for creating a substantially horizontal airstream; a feed system for receiving a crystalline feed material and injecting the feed material into the cyclone upstream from the fan so that the feed material contacts blades of the fan; a source of fuel feeding into the cyclone wherein the fuel is mixed with the feed material by action of the fan; a torch for igniting the airstream containing the feed material and the fuel exiting the cyclone, the torch configured so that particles of the feed material are melted into molten droplets in a flame of the torch; a cooling chamber spaced horizontally apart from the torch and into which the flame of the torch is directed horizontally at a first end thereof, wherein the molten droplets form solid micron-sized polymorphic particulates; a collection system for collecting the solid polymorphic particulates, the collection system disposed at a second end of the cooling chamber spaced horizontally apart from the first end.
