Abstract
PURPOSE: To improve a grinding characteristics by a method wherein two parallel rotating shafts having grinder materials properly spaced apart and shaped to have a larger surface area thereon are stored in a casing, a lower half part of the casing is made to be the same shape as that of a leading end of the grinder material and an upper half part of the casing has a larger space.
CONSTITUTION: High antiwear grinding materials having a low rought surface are arranged on the opposite parallel rotating shafts 1, 2 in such a way as the desired space for enabling the peeled-off sands to be moved freely is made between the shafts and their surface areas are made to be large, and then the shafts are stored in the two-split casing 4. Lower casing 5 is made to be coincided with a circumferential contour surface of the grinder material 3. Sand removing port 7 is made in a side plate 6, the upper casing 8 is provided with such a space as facilitating a movement of the floating powder dusts. Under this arrangement, a grinding characteristic can be improved.
