Abstract

The invention can be used in the production of abrasion powders, ceramics, conducting paste in microelectronics, etc. The grader comprises a housing (1) inside which is mounted a rotor (2) with rigidly attached discs (3, 4, 5), a material inlet pipe (6), pipes for removing the coarse and fine fractions (7 and 8 respectively). Grooves (9) are provided on the disc (3) on the pipe (6) side and serve to create turbulence. Vanes (10) are arranged between the discs (4, 5) for removing the fine fraction particles.

The intensity of the impact of the vortex grinding in this device depends on the number of processors. The intensity of exposure will increase with an increase in the rate of rotation of the rotor and decrease with its decrease. As for the separation of the available large particles, the size of the separation is 40-50 μm. When the rotational speed of the rotor is small (1500-1000 rpm) and the particles themselves have a sufficient mass and kinetic energy, which is beneficial to the destruction of the aggregates, the influence of This does not result in additional grinding of large particles. In addition to a separation of 2-5 μm, when the rotation speed is high (5000 - 4000 rpm), the air-dispersed mixture is 10-minute. it is quite enough for the fact that there was an intense vigorous perturbation caused by the grooves on the disk. And, in the case of the indicated speed of movement, the particles of a lot of things happen between themselves, which leads to more effective destruction of the aggregates than this does to the consumer. 4 The presence of a zone of vertical dispersion of aggregates makes it possible to increase the efficiency of separation of small fraction of the disease from the disruption of aggregates. Separation of fronts with initial sizes of less than 10 μm.
