mill performance is based on mill diameter and length only increases or decreases capacity. the slice mill is simply a mill of the same diameter as the production mill but much shorter. slice mill of 72 diameter by 12 wide would replicate the result of a normal production, mill 72 in diameter as 120 long.
maximum rule is drawn by a mill when the attack occupies almost 50% by compass. however, as seen in figure the rule deflexion becomes very even in the rove overhead 45%. As a consequence, mills are infrequently run behind a while attack smooths greater than 45%. In rod mills, the attack is distended by particles of heal which disunited the rods.
