Milling Your Own Lumber | Popular Woodworking

First, and maybe the most obvious, is the cost. Milling your own lumber can produce quality material for a fraction of the price of a lumber dealer. In fact, if you purchase your own mill, like I have, you can actually make a profit off of it by selling lumber to other woodworkers and by offering to mill other people's logs. 3.

Autogenous Grinding & Semi Autogenous Grinding Circuits

Wet Versus Dry Primary Grinding. From the standpoint of operating costs, it is to be expected that liner wear, and, where a small ball charge is used, ball wear would be higher in wet grinding than in dry grinding.
