ABSTRACT:
The improved hydrocyclone separating method and apparatus provides negative pressure to feed the hydrocyclone and an artificial air core into hydrocyclone. Use of the negative feeding pressure allows reduction of the cyclone pressure drop and energy consumption. The water content in the underflow solid product is decreased. Use of the artificial air core allows to obtain a high separation efficiency. Use of this hydrocyclone allows extraction of solids from liquid before the feeding pump and therefore to prevent abrasion of it.
