CANE MILL

PURPOSE:To obtain a cane mill capable of precisely controlling malleation even during operation by pivoting a pair of oscillating arms supporting a top roll at the top through an eccentric pivot mechanism to a frame at the base end part. CONSTITUTION:One top roll 3 is arranged so as to be nearly parallel to a pair of parallel lower rolls 2 and 2 and locate at nearly equal distance to these rolls 2 and 2 above these parallel lower rolls 2 and 2 opposite to each other at definite interval. Further, a pair of oscillating arms 6 and 6 each supporting both end parts of roll shaft of the top roll 3 at the top are pivoted so as to enable to change the position through an eccentric pivot mechanism 20 cooperatively operating with a shaft member and core shaft member at the base end part to a frame supporting three rolls. The ratio A/B between roll space A on inlet side and roll space B of outlet side is set to prescribed value and when operation condition is changed after starting operation of cane mill, eccentric sleep 24 of an eccentric pivot mechanism is rotated to control the ratio A/B.
