from The Century Dictionary and Cyclopedia
- n. A building or plant where tubes are manufactured.
- n. A rolling-mill for rolling tubes, as by the Mannesmann process, which produces a tube with the fibers running in a helix so as to withstand internal pressures.
- n. A grinding- or pulverizing-mill used for pulverizing cement clinker. It consists of a revolving tube in which is placed the material to be ground, together with a quantity of pebbles. As the tube turns, the action is very similar to the grinding of pebbles on a beach.
Sorry, no etymologies found.
Example: In Class 80, Metal-Rolling, it would not be expected to find any tube-rolling mill lower in the schedule than the tube-rolling subclasses, but a tube-mill might be found higher up in "Heating and rolling," "Drawing and rolling," etc.
Chert or flint constitutes grinding pebbles and tube-mill linings, and is also ground up for abrasives.
