FIELD: machine building.SUBSTANCE: aerodynamic vertical activator of gravitation type comprises a vertical grinding chamber. The chamber is made in the form of a hollow cylinder, in covers of which there is a shaft installed as capable of rotation. At least two working discs are fixed on the shaft. On each surface of the working disc there are dashers installed as protruding beyond its edges. In the wall of the grinding chamber there are rods installed so that during rotation of discs with dashers the rods are arranged between dashers. Grinding and activation of loose materials is carried out with speeds of particle movement from 100 to 150 m/s.EFFECT: increased extent of material activation, increased extent of particle disintegration at high efficiency, an activator may adjust speed of particles acceleration within specified limits.11 cl, 2 dwg |
