Abstract
A centrifugal separator for separating the solids component of a feed liquid comprises a bowl that is rotatable about a vertically disposed axis. The bowl has an interior wall, a conical lower end and a generally cylindrical portion. The conical lower end includes a central opening and defines a lower edge which has a first diameter and an upper edge which has a second greater diameter. A fluid applicator that is moveable between a stowed position and an application position may apply the feed liquid to the interior wall adjacent to the lower edge of the conical lower end so that as the bowl rotates, the angular velocity of the feed liquid gradually and non-traumatically increases, gently forcing the feed liquid upwards along the wall of the conical lower end and into the generally cylindrical portion of the bowl.
