Abstract
A sizing roller screen apparatus and method for processing an ore feed received at an inlet is disclosed. The ore feed includes sized ore portions and oversize ore portions. The apparatus includes a roller screen having a plurality of adjacent screening rollers supported to provide interstices therebetween for permitting passage of the sized ore portions between the adjacent screening rollers, the adjacent screening rollers being operably configured to rotate to cause a first sized ore portion to pass through the interstices while the ore feed is being transported along the roller screen. The apparatus also includes a sizing roller disposed generally above an opposing one of the plurality of adjacent screening rollers, the sizing roller being operably configured to rotate to fragment at least some of the oversize ore portions passing between the sizing roller and the opposing screening roller to produce a second sized ore portion, the second sized ore portion being sized for passage between the interstices.
