Material is delivered to the centre of a vortex of a compressed gas, which is used to strip and heat the material, which is converted into a dry powder. A method for dewatering a material and breaking it up into particles comprises delivering the material to the centre of a vortex of compressed gas (e.g. air). The vortex generates a vacuum (21) with the aid of a processor comprising an inlet part (16), a tubular conical part and an outlet part at the narrow end of the conical part. The compressed medium is forced to rotate in a spiral manner through the processor, around the conical part periphery and onwards, in order to carry the material whilst it is being heated. The material is then made to explode or burnt whilst simultaneously dewatering it and drying, forming a dry powder which can be removed from the outlet part of the processor. An Independent claim is also included for the apparatus used to carry out this method, the inlet part having a compressed medium inlet oriented at a tangent to its periphery. |
