In this operation, the metal is passed between two rollers that rotate at the same speed but it is in the opposite direction. It is used in slabbing, plumbing, rail, plate roughing work and many other areas. As there is the need for a reversible drive, this mill is cheaper compared to the others. Two High Non-Reversing Mills:

in roller mills, three criteria are essential in producing a 700- to 800-micron particle size: (1) the rolls should be moving with a differential drive of one roll moving 50 to 75 percent faster than the other to produce a shearing action that will help "cut" the kernel rather than crush it; (2) the rolls should have corrugations to help slice …
