METHOD OF CENTRIFUGAL-VIBRATION SEPARATION OF MIXTURES Russian patent published in 1999 - IPC

FIELD: mining industry, in particular, methods of concentration of sands, ore ground material and technogenic formations of gold, platinum and other heavy metals. SUBSTANCE: method includes supply of suspension to rotating bowl with riffles. Suspension is acted upon by varying centrifugal field with parameters calculated by bowl maximum diameter. In this case, maximum field value-minimum field value ratio is set up within 1.4 to 3.5, and frequency of action cycles is from 1.1 to 3 for one revolution of bowl. EFFECT: higher efficiency of mixtures separation. 2 dwg
