How Should You Match the Sawmill to Your Logs?

Step 1: Measure the actual log supply

Record the usual and maximum log diameter, length, taper, sweep, moisture condition, and expected daily volume. Do not size the machine from a single exceptionally large log.

Step 2: Define the product mix

A mill producing pallet boards may need a different workflow from a mill producing high-value flooring blanks or wide slabs. List the required board thicknesses, widths, grades, and acceptable recovery targets before comparing machines.

Step 3: Select the handling system

Log handling often limits daily production more than the saw head. If operators must manually roll, turn, or clamp heavy eucalyptus logs, fatigue and downtime can quickly reduce output. Hydraulic loaders, log turners, powered clamps, and automatic carriages can improve both safety and throughput.

Step 4: Confirm blade and feed compatibility

Ask the manufacturer which blade profiles, tooth pitches, tension settings, and feed ranges are recommended for the eucalyptus species and log sizes you process. The goal is not to run the blade as fast as possible; it is to maintain a straight cut, acceptable surface quality, and stable blade life.

Step 5: Calculate the complete operating cost

Include:

Fuel or electricity.

Blades and sharpening.

Hydraulic and engine maintenance.

Labor for loading, sawing, edging, stacking, and sorting.

Transport and site preparation.

Downtime and spare parts.

Waste handling and recovery losses.

A low purchase price does not necessarily mean a low cost per usable board foot.
