摘要： A media-agitation type pulverizer of the present invention includes: a guide ring installed to radially divide a lower region of a pulverization chamber into an inner section and an annular outer section. A flow of a mixture of a raw material slurry and pulverizing media is formed as a helicoidal flow comprising a secondary flow flowing through a circulation flow path which has an upward flow path and a downward flow path created, respectively, in the outer section and the inner section of the lower region of the pulverization chamber, with respect to the guide ring. A rotational-flow suppressing device is provided within the pulverization chamber and adapted to strengthen the secondary flow of the helicoidal flow, thereby stabilizing the helicoidal flow. As a result, a media-agitation type pulverizer is provided which is capable of creating a uniformized, stable helicoidal flow in a mixture of pulverizing media and a raw material slurry, without unevenness of a centrifugal force distribution, thereby performing pulverization/dispersion uniformly with satisfactory energy efficiency.
