Abstract of the Disclosure The invention provides an improved vertical type pulverizing and classifying apparatus comprising a lower, pulverizing chamber and an upper, classifying chamber, wherein a material under treatment is carried by gas streams. The disclosed apparatus includes a conduit between the pulverizing chamber and the classifying chamber for sending particles of the material emerging from a primary classification to the classifying chamber for a secondary classification. A floating chamber is provided circumferentially of the conduit to receive particles descending from the classifying chamber for a further classification, whereby resulting fine particles are blown back to the classifying chamber and coarse particles are returned to the pulverizing chamber by way of a material feeder.
