ABSTRACT:
A roll mill has a fixed roll journalled in stationary fixed bearings and a floating roll journalled in movable bearings enabling the floating roll to be pressed against the fixed roll under high pressure. An adjustable spacing arrangement is provided between the two bearings to enable a gap of selected width to be formed between the rolls. The spacing arrangement includes a pair of shaft-like distance members received and guided in associated bores of the fixed bearings for movement therealong. Free ends of the distance members extend outward of their bores and engage the opposing floating bearings to adjust the positions of the rolls as they wear so as to maintain the selected gap width. The free ends are retractable into the bores to allow the bearings to abut one another and thereby optimize the wear life of the rolls.
