Re: Lead Times on New Saw Mills. I shopped a new TK2000 a few months ago and I think they said 9 weeks lead time. Might be a bonus for folks that already own a mill and thinking about an upgrade. The guys at TK said the long lead times are keeping the prices of good used mills close to the price of a new one.

Mill scale (also called scale) is the flaky surface that forms on hotrolled steel. Its composition includes FeO (iron (II) oxide), Fe2O3 (iron (III) oxide), and Fe3O4 (iron (II,III) oxide). You will find mill scaling on steel sheets, plates, and profiles. It arises when you roll hot steel billets or iron in rolling mills.

A more accurate basis for calculation of tonnage in a grinding circuit is the screen analysis. Samples of the mill discharge, return sand, and the classifier overflow are screen sized, and the cumulative percentages are calculated on several meshes. Let: d = cumulative percentage on any mesh in the mill discharge,

For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill.
