FIELD: chemistry.SUBSTANCE: invention can be used in chemical industry and in electrical engineering. Water suspension, containing, vol %: coke particles 4 with size 1-8 mcm - 50-70%; the remaining part -water, is placed in internal cavity of reservoir. Particles of aluminium oxide and/or silicon oxide with the same size are additionally introduced into suspension in amount 1-10 vol %. Suspension is subjected to impact with rotating magnetic field with intensity 5×10÷1×10A/m and frequency 40-70 Hz, which is formed by working elements 1, made in form of connected to each other plates from magnetically conductive material, forming rectangular contour. Three coils 2, each of which is connected with respective phase of external three-phase source of electric power, are located in the body of separate components, which constitute contour. Isolating cover 8 is installed on upper butt end of reservoir 3. On the bottom of reservoir 3 blanked off from the butt end pipe branch 6, in walls of which perforation holes 7 for supply of jets of compressed air under excessive pressure 0.1÷0.6 kgf/cm, creating "boiling layer", is laid. Time of processing is 6-20 minutes.EFFECT: invention makes it possible to obtain different composition material from cheap and available raw material, reduce expenditures, simplify construction of device and process due to reduction of stage quantity.2 cl, 3 dwg, 6 ex |
