Abstract:
1. A centrifuge comprising a housing, a rotational mechanism, a basket, a rotating feed pipe and a programmable logic controller, wherein: the housing comprises at least one side and defines an interior volume; the basket is positioned in the interior volume of the housing and operatively coupled to the rotational mechanism such that rotation of the rotational mechanism is imparted to the basket; the rotating feed pipe extends into the basket through a pipe support positioned over the basket or through a basket lid or cap, wherein the rotating feed pipe comprises a nozzle operable to direct a slurry of solid particulates suspended in a liquid onto a sidewall of the basket and the rotating feed pipe is operable to rotate in the pipe support from a first position towards a second position thereby increasing the distance between the nozzle and the sidewall and varying an angular orientation of the nozzle with respect to the sidewall as a cake deposits on the sidewall of the basket, and the programmable logic controller being programmed to rotate the feed pipe at a predetermined rate based on the deposition rate of the cake.
