Abstract: Improved hydrocyclone separators are adapted for connection to an improved header having concentrically arranged feed and accept nipples. The hydrocyclone includes feeding means including unique guide vane means for swinging the feed suspension from a generally longitudinal direction to a generally spiral direction and accelerating same prior to feeding the suspension into the separation chamber. The accept outlet includes an elongated tubular member with the guide vanes being located in the annular region defined between the tubular member and the wall of the chamber. The wall of the separator chamber terminates at the large end thereof at an annular rim the latter being connected to the feed nipple. The elongated tubular accept outlet has an end portion concentrically arranged relative to the annular rim of the separator chamber for connection to the accept nipple which is concentrically arranged relative to and within the feed nipple.
