METHOD AND EDDY MILL FOR VORTEX GRINDING Russian patent published in 1996 - IPC

FIELD: chemical engineering. SUBSTANCE: eddy mill has cylindrical milling chamber with tangential supply of power carrier and with peripheral and central outputs and charging vortex chamber in which power carrier worked out in milling chamber is used for ejection of ground material. The method is carried out by tapping part of power carrier into charging chamber at the unbroken supply of ground material as well as by tapping all ground product into peripheral output in the form of suspension of matter in gas. The peripheral output is made classifying. EFFECT: enhanced efficiency of solid materials. 5 cl, 3 dwg
