Sawmill recovery rate - woodweb

Recovery rate is not the most important factor in a production mill setup. When I ran a circle blade we would saw a lot of 12 to 14 inch logs into cross ties and get 4 boards off the sides. My band mill does no better other than the fact that I can take a bit more time and often get a better board and trim a bit better.

Increase Plant Throughput by Mill Expansion

Shortly after start-up, it was apparent that it would be difficult to obtain the plant design throughput. The ore sample that had been used for grinding test work was found to be much softer than that of the orebody in depth. This had led the designers to design without a crushing stage and to designate the primary semi-autogenous mills as scrubbers rather than mills. On start-up, it was found ...

Sawmill recovery rate - woodweb

Question It looks like bandsaw mills have a higher recovery rate than circular mills do. My reasoning is that if you are buying logs by the board foot and are being paid by the board foot, you would get more board footage with a bandsaw mill, which means you would make more money, plus you may get overrun, more footage of lumber, than what you bought the logs for.

High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.
