Barked or debarked green or dry logs are fed into such a machine one after other. Logs are milled into shape which, depending on style, results in cylindrical or square beams [ 1 ] . These different profiles are customizable depending on construction method : Swedish cope, Tongue&groove, D-log, bevel-edged, etc.
The once-ubiquitous rusty, steel conical sawdust burners have for the most part vanished, as the sawdust and other mill waste is now processed into particleboard and related products, or used to heat wood-drying kilns. Co-generation facilities will produce power for the operation and may also feed superfluous energy onto the grid.

Various industries and trades use kilns to harden objects made from clay into pottery , bricks etc. [ 3 ] Various industries use rotary kilns for pyroprocessing —to calcinate ...
When free hydroxyl groups are transformed to acetoxy groups, the ability of the wood to absorb water is greatly reduced, rendering the wood more dimensionally stable and, because it is no longer digestible, extremely durable. In general, softwoods naturally have an acetyl content from 0.5 to 1.5% and more durable hardwoods from 2 to 4.5%.
