Portable band sawmill: A band
sawmill features a band saw attached to a log bunk. The log is placed on the
bunk. The band saw blade is typically set on rubber wheels and the blade
travels down the length of the log. The log bunks and tracks determine the
thickness of the completed board.

Portable chain sawmill: A chain saw
mill consist of one or two chain saw attached to a pair of rails. The rails are
able to sit on the log and travel across it while the chain saw cut the wood.
The distance between the rails and the bar of the chain saw is what will dictate
the thickness of the board.

Portable swing blade mill: Swing
blade mill use circular blades. They are gas- powered and are usually
automated. They are typically used for larger logs and can be adjusted to cut
many different sizes of boards.

Steam – powered sawmills: These were
developed in the united state in the 19th Century. These types of
sawmill were built in areas away from water and were far more efficient than
older mills.

vii.
Computerized sawmills: Today’s
sawmills are largely computerized and run on electricity. Computerized mills
emphasize highly efficient production, along with safety and waste reduction.
As they are expensive to build, they typically require a high level of
production in order to return profits.

Gasoline powered sawmill: It
operates on a smaller basis than computerized sawmills. They were common early
in 20th Century and exist on small scale today. They are typically
run by private entrepreneurs.
