To provide a medium-type powder treating device in which agitation in a container is accelerated by promoting circulation in the vertical direction of medium powder so as to develop a higher treating performance, in particular to develop a high crushing performance and a high drying performance, and in addition in which a product recovery from feed of a raw material can be effectively carried out by effectively reducing a deposition of particulates to the inner wall of the container.
In the medium-type powder treating device provided with agitating members 4, freely rotatably around the vertical shaft, which projects a plurality of rods 3 over one or a plurality of steps in directions of the outer diameter, a blade 5 in which a collision surface to a material to be treated and a medium particle 6 is tilted to a horizontal surface is installed at the end part of the rods 3.
