Adjacent rolls rotates in opposite direction. So that the material may be passed between the top and the middle roll in one direction and the bottom and middle rolls in opposite one. In three high rolling mills the work piece is rolled on both ...A pass-line adjusting mechanism is disclosed in association with the chocks of the lower back-up roll of a four-high rolling mill. The adjusting mechanism includes an axially slidable adjusting member having vertically stepped surface portions corresponding to each lower back-up roll chock,

Advantages & Disadvantages [PDF] Belt Drives are used to transfer power from one shaft to another. This is one of the easiest and cheapest ways to transfer power in a machine. Let us learn in this article more about types of Belt Drive for grinding heavy rollers. c. Piston Grinder. Pistons of I.C. engines are required to be grinded not in round shape but in oval and taper shape so that when their size increases due to heat these may not get deposited in the cylinder.
