ABSTRACT:
An improved screen basket for use with a centrifuge includes two adjoining screen sections. The first screen section is formed from a wear resistant material and is located proximate to the point at which slurry is introduced into the basket. The length of the first screen section is chosen so that the majority of potential wear caused by the abrasive slurry occurs within the first section of the basket. The second screen section is preferably formed from less expensive materials, such as steel wedge wire. The second screen section smoothly joins the first screen section and provides for further dewatering or separation of the accelerated slurry so that a dry cake is produced by the centrifuge.
