    Rubber compounding was performed on a two-roll mill (Lab Walzwerk MT 6″×13″, Rubicon, Germany) in a three-stage process. In the first stage, the rubber was mixed with zinc oxide, stearic acid, CB, and Struktol or IPPD. Then the rubber/MLG masterbatch was added to the rubber compound in the second stage

    How the Three Roll Mill Works. The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion

    J.F. Cameron, C.G. Clayton, in Radioisotope Instruments, 1971 Cold-strip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.. It has long been recognized that some, if not most, of the variations in thickness of strip produced
