Abstract: A classifier and a method of separating material using such a classifier are disclosed. The classifier comprises a mixing chamber having a mixing fluidisation floor and a concentration chamber having a concentration fluidisation floor. The concentration fluidisation floor and at least a portion of the concentration chamber is located below the mixing fluidisation floor. The method of separating material using such a classifier comprises delivering material to be separated into a mixing chamber of the classifier, fluidising the material in the mixing chamber; transferring some of the material to a concentration chamber of the classifier in fluid communication with the mixing chamber, fluidising the material in the concentration chamber, forming a concentrating fluidised bed in the concentration chamber, separating the material with at least the concentrating fluidised bed and drawing heavier portions of the separated material from the concentration chamber.

Abstract: A classifier cleaning and optimization device is provided. The device includes a chamber that is adapted to contain a fluidized bed, an array of two or more adjacently arranged inclined plates positioned above the fluidized bed wherein an inclined channel is formed between each pair of adjacent inclined plates, and a means for introducing a process liquid into the chamber between the fluidized bed and the array of inclined plates such that in use, the process fluid travels through at least one of the inclined channels. A method of cleaning the separation section of a classifier is also disclosed herein.

Abstract: A scroll screen centrifugal separator includes a distributor that is configured to receive slurry received from a feed conduit. The distributor is configured to deflect the received slurry to a screen of the scroll screen centrifugal separator. In some embodiments, the distributor may include a distributor that has a flat surface encircled by a lip or having one or more lips positioned on the flat surface, an inclined surface, or a declined surface that faces the mouth of the feed conduit. In other embodiments, the distributor may include a plurality of dam members for defining passageways through which slurry is passable through the distributor prior to being ejected to a screen of the separator. In other embodiments, the distributor may include a distributor plate that has a plurality of radial arms attached thereto that are configured to direct slurry to the basket with a rotational velocity.

Abstract: A scroll assembly for a centrifuge that includes at least one lamellae pack assembly (11) proximate the first end of the scroll. The lamellae pack assembly (11) may have a plurality of lamella plates and be positioned upstream of a weir (31) or an effluent exit port (4) that permits a liquid fraction (33) of said infeed slurry to discharge from the centrifuge. The lamella plates are preferably configured and arranged to bias fine solids (35) entrained within the liquid fraction (33) radially-outwardly or at least hinder their radially-inwardly migration as the liquid fraction (33) passes through the lamella plates and before the liquid fraction passes the weir (31) or effluent exit port (4), in order to produce discharged clarified liquids (36) which are substantially-free of the fine solids (35).

Abstract: A fluidized bed separator (1) includes a feed section (4) between an upper sep- aration chamber (19) and a main separation chamber (6). The feed section (4) has one or more feed pipes (11) extending horizontally and transversely with respect to a body wall (10) of the fluidized bed separator (1). The one or more feed pipes (11) are positioned completely and entirely underneath the inclined plates (17). An external oversize protection apparatus (3) which is separate from and external to the body wall (10) may be operatively coupled to the one or more feed pipes (11). One or more lamella cartridges (49) may be provided within channels (18) of the upper separation chamber (19), and one or more breakaway plates (54, 55) may be inserted within channels (18) to prevent sanding and fa- cilitate insertion and extraction of the lamella cartridges (49).
