[specific embodiment]

Referring to Fig. 1, a kind of centrifugal mill comprises frame 1 and cylindrical shell 2, and cylindrical shell 2 is fixed on the frame 1, is provided with charging aperture 6 on the top of described cylindrical shell 2, is provided with discharging opening 11 in the bottom of described cylindrical shell 2, and bar 7 is installed below charging aperture 6; Be provided with at least two layers of capstan 3 in cylindrical shell 2, this capstan 3 is installed on the main shaft 4, and described main shaft 4 is sleeved in the bearing 5, and be installed in the middle part of cylindrical shell 2, the one end is connected with big belt pulley 16 power, and the other end is installed on the cylindrical shell 2 by bearing 5, and the bottom of bearing 5 is contained in the bearing block 13; Be provided with awl liner plate 9 on other each layer capstan 3 of the bottom and grind ball 8 described removing, be provided with awl liner plate 9 and grind ring 10 on the capstan 3 of the described bottom, as shown in Figure 2, described capstan 3 is provided with at least two lattice, grinding ball 8 places in the lattice, as shown in Figure 3, described capstan 3 is provided with at least two lattice, grinds ring 10 and places in the lattice, what of capstan 3 numbers of plies, the lattice number of every layer of capstan 3, grind in every lattice ball 8 what, grind what of ring 10, decide by the granularity requirements of material.
