In a cyclone classifier wherein the material to be processed is swirled in a tubular casing having a conical lower portion and classified, a cylindrical body is provided in the casing, so as to surround the lower end of a fluid outlet pipe and extends downwardly below an inlet port for the material to be processed, so that the sectional area of passage for the material to be processed swirled in the casing will be made smaller, thus increasing the classifying point while keeping the pressure loss at a minimum. From another aspect, annular pipes formed with fluid inlet ports are provided around the outer periphery of a lower part of the casing so as to communicate with the casing so that gases or liquids will be blown into the lower part of the casing through these pipes to form a swirling current, thus allowing the material to be processed to be reclassified thereby increasing the classifying point.

A cyclone classifier comprising: a tubular casing having upper, middle, and lower parts, said tubular casing including a peripheral wall defining an inside and an outside, and said lower part of said tubular casing including a substantially conical portion; an inlet pipe means at said upper part of said tubular casing for supplying gas and material to be processed into the inside of said casing, said inlet pipe means having an inlet port means for directing the material to be processed into said casing and in a direction tangential to said peripheral wall of said casing; a discharge pipe means for discharging solid particles and being at said lower part of said tubular casing; an outlet pipe means for discharging gas and classified material from the inside or said tubular casing, said outlet pipe means extending from inside said casing, through said upper part of said casing, and outside said casing, said outlet pipe means having a first opening inside said casing and a second opening outside said casing; a tubular body having upper, middle, and lower parts, said tubular body including a peripheral wall defining an inside and an outside, said lower part of said tubular body being open and surrounding and extending past said first opening of said outlet pipe means, and said peripheral wall of said tubular body being spaced from said peripheral wall of said tubular casing for defining a space for further directing the material to be processed directed by said inlet port means of said inlet pipe means in a direction tangential to said peripheral wall of said casing; a conic being attached to said casing, located inside said casing, being spaced from said peripheral wall of said casing, being spaced from said tubular body, and being spaced from said first opening of said outlet pipe means, said conic having substantially conical upper and lower ends, and being located between said first opening of said outlet pipe means and said discharge pipe means; and an annular gas inlet pipe means substantially surrounding said peripheral wall of said lower part of said tubular Casing, said annular gas inlet means having an inner and an outer annular peripheral wall, a gas inlet port in said outer peripheral wall for introducing gas into said annular gas inlet pipe means in a direction tangential to said annular peripheral walls thereof for causing a smooth swirling tangential gas current there±n, a gas outlet port in said inner peripheral wall of said annular gas inlet pipe means, said gas outlet port extending around substantially the entire inner peripheral wall for fluidly communicating with said lower part of said tubular casing substantially around the entire circumference thereof for causing a smooth swirling tangential gas current in said tubular casing.
