A centrifugal separator includes a chip bowl for receiving a fluid-particulate mix and delivering the mix onto the screening surface of a cylindrical separator screen disposed around the bowl. A canopy portion of the bowl overlaps the separator screen and is axially positionable therealong such that a variable length of the separator screen may extend beyond the forward edge of the bowl. A separator drive shaft has an axial bore for housing a bowl drive column and an adjusting rod. The bowl drive column is mounted to the separator drive shaft and adjusting rod such that axial movement of the adjusting rod causes axial movement of the bowl drive column but not the separator drive shaft and rotation of the separator drive shaft causes rotation of the bowl drive column but not the adjustment rod. A threaded surface on the adjusting rod threadably engages an adjustment spindle such that rotation of the adjustment spindle causes the adjusting rod to move longitudinally and adjust the position of the canopy portion in relation to the screen. A scale is coordinated with a pointing device mounted to the adjusting rod to provide a means for determining the length of the separating screen which extends beyond the edge of the bowl.
A method for separating the particulate component of a fluid-particulate mix upon rotation of a separator about a rotational axis, the separator having a spreader member for initially receiving and diffusing the mix to be separated and a screening member having a surface area for receiving the mix from the spreader member and separating the mix, comprising the steps of:
