ABSTRACT OF THE DISCLOSURE An apparatus and a process for pulverizing a material by friction with a pulverizing medium such as steel balls by rotating a screw shaft rotatably mounted in a shell. A plurality of screw shafts are used for more efficient pulverization. A disc having its lower surface in the form of an inverted cone is secured to the screw shaft to avoid runout. A partitioning plate is provided between each pair of the adjacent screw shafts and formed with one or two holes to allow communication between the chambers formed by the partitioning plates. This assures that the material is discharged after fully pulverized.
