A cylindrical vessel has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent thereof. This drive shaft is rotatably driven by a motor at a speed of 1,500-10,000. Solid particles to be comminuted which may be of coal and limestone/dolomite or lime are fed into the vessel. Connected to the shaft and rotatably driven therewith is a centrifugal compressor fan which forms an uplifting air curtain which suspends the particles. Mounted above the compressor and rotatably driven by the drive shaft are a plurali...
[ I claim:] [11.] A method for comminuting solid particles comprising the steps of:feeding said particles in a gas stream into a vessel;driving said particles and said gas stream upwardly so that they are suspended in said vessel;comminuting said particles in a vortex zone formed in said vessel;feeding the comminuted particles to a cyclone to separate said particles from said gas stream;recycling the gas stream from said cyclone back to said vessel; andremoving moisture from said gas stream during said recycling.
