A multi-zoned paddle screen apparatusis disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus includes a housinghaving first and second zonessituated adjacent one another along a length (L) of the housing. First and second screen sectionshaving a plurality of openingsmay be situated lengthwise within the housingcorresponding with the first and second zones, respectively. The first and second screen sectionshave a circular cross-section, and the second screen sectionhas a larger diameter than the first screen section. An elongated shaftsituated lengthwise within the screen sectionsincludes first and second conveyors, which correspond with the first and second zones, respectively, having a plurality of paddles. Each conveyoris configured to move material in a direction along a length of the screen. There may be more than two zones

Multi-zoned paddle screen apparatus

A pressurized cyclone for separating solid material from a fluid flow in which the solid material is entrained in a gaseous fluid maintained in an elevated pressure. The cyclone includes a housing having upper and lower ends and defining a longitudinal axis. An agitator assembly is positioned within the housing proximate the lower end, and includes a plurality of radially extending agitator members supported for rotation about the longitudinal axis. A plurality of radially extending anti-rotation members are removably supported within the side wall, wherein the plurality of anti-rotation members are axially spaced relative to the plurality of agitator members. A motor is operably connected to the agitator members for rotating the agitator members about the longitudinal axis whereby the agitator members move relative to the anti-rotation members for agitating the solid material.

Pressurized cyclone including agitator assembly

A multiple hydrocyclone assembly includes a closed tubular vertical housing enclosing two concentric vertical cylinders which cooperate with the housing to define an inner cylindrical outlet chamber and concentric annular inlet and outer outlet chambers. Multiple hydrocyclones or cyclonettes are mounted in axially extending vertical rows and in corresponding radial positions in the cylinders from the outer surface the outer cylinder, and the housing and concentric cylinders are formed in sections which are coupled together in end to end relation. Individual cyclonettes can be removed and replaced after removal of one or more of the housing sections. In order to increase the pressure of the feed stock to be cleaned which is supplied to the cyclonettes in the upper portion or sections of the assembly, vertically extending flow channels are provided in the lower portion of the inlet chamber by omitting cyclonettes from the rows in the lower sections of the assembly.
