Start with the material—not the catalogue
Two projects asking for the same hourly tonnage may need different machines. Uniform plantation logs, tangled branches, roots and construction timber load the feeding and cutting systems differently.
Record wood species, moisture, typical and maximum diameter, length distribution and contaminants. A short feeding video often provides more useful evidence than a material name alone.
Define sustained capacity
Specify the average production required over a shift, not only an instantaneous peak. Include loader cycle time, knife inspection, screen cleaning, refuelling and downstream stops. Capacity claims should always be tied to a defined feed material and finished size.
Confirm chip use and size
Boiler fuel, panel furnish, compost bulking material and hammer-mill feed have different acceptable size distributions. If oversize must be removed, include a screen and return path in the line design.
