To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and.
Roll Weight. To find the approximate weight of a roll, multiply roll diameter squared minus core diameter squared by roll width and appropriate factor.

The transition between these layers is metallurgically and mechanically sound and is substantially below the scrap diameter of the pinch roll. The outer working layer of this blend is a white-iron based alloy enriched with modest amounts of Chromium, Molybdenum, and Nickel.
To determine the size of mill drive required, factors such as the diameter and weight of the jar mill should be considered the largest diameter jar that could be used on this series of roll drives is a 10 diameter jar, the length of the jar and the number of grinding jars to be used simultaneously. If it were desired to grind four 5 diameter by 8 long jars at one time, 4 x 8 2.
Calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given. An example of rolled material would be a rolled carpet or a rolled sheet of stone from the stone mill. The length units that.
3. Length minimum and maximum. 4. Notching or secondary operations. 5. Reference to mating parts. 6. Attention to critical areas. If a worn-out sample roll is submitted instead of a roll drawing, the manufacturer should take the time to reverse-engineer the roll, make a new drawing, and get it approved by the customer to avoid any misunderstandings when the new roll tooling is delivered.
