摘要： A hydrocyclone separator and a method for classifying solid material in liquid suspension are presented. The hydrocyclone separator comprises a head portion having an inlet conduit and an overflow discharge tube arranged in the head portion. The hydrocyclone separator further has an apex discharge port and a tapered separation portion arranged between the head portion and the apex discharge port. The tapered separation portion is tapering distally away from the head portion. Moreover, the hydrocyclone separator has a flow support portion with at least one flow support inlet configured to inject a fluid along at least a portion of an inner surface of the flow support portion towards the apex discharge port, when the hydrocyclone separator is oriented such that the apex discharge port is at a vertically elevated position relative to the overflow discharge tube. Hereby, a hydrocyclone separator capable of achieving improved operational efficiency with reduced risk of clogging the apex discharge port is presented.
