Achieving faster, more efficient tube mill changeovers

If brass washers are used on the top and bottom of the side rolls, they can be converted to thrust-type bearings. This eliminates the wear variables of the brass washers. On "M"-style mills using solid tooling, the metal line drops, thus requiring the side roll passes to be lowered to match the new metal line.

Roll forming basics - The Fabricator

Roll Forming a Tube. Now let's roll form the same 2-in.-diameter tube with prepunching. The process requires 10 passes before the welding station, because a typical roll former doesn't have idler stands. Tube and pipe mills use idlers between almost every pass to assist in forming the round.

Container Handbook - Section 3.1 Container design

ISO standard 1161 specifies different shapes for top and bottom and mirror images for right and left. The eight corner castings of a container or a corresponding CTU have to be particularly strong, since they work with the corner posts and the other basic components of the container frame to absorb the forces which lock units or lashings exert on containers when they are stacked on top of one ...

Examining tube mill roll tooling, setup, and maintenance

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.

Solving problems on the tube mill

6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.

Tube Calculator - Rogue Fabrication

Vehicle load is a static distributed load in the middle of the longest tube and is 1/3 the tube length. Loading in the middle of the longest tube is a worst case for stress on a cage member. Square tube assumes bending with one side parallel to the load (think square vs diamond). The safety factors use the numbers in the table below for strength.

Pulverizer - Wikipedia

A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry. Both types of mill include liners that protect the cylindrical structure of the mill from wear.

Don't get flattened by the wrong plate roll

The plate is held securely in place between the top and bottom rolls, while the side rolls move vertically to create the bend. The bottom roll moves up to hold the plate surface securely against the top roll while the side roll is raised to form an accurate prebend, minimizing the flat zone on the plate edge.

Paper Machine Winder Slitting - Convergence Training

On most winders, the top slitters are sharp circular blades and the bottom slitters are bands. The top blade slightly overlaps the bottom band and is loaded from the side to cut the sheet using a shearing action, like scissors. When roll sizes change, how are the slitters repositioned? Slitters can be repositioned manually or automatically.
