Sawmilling Process

How we do it

Here at Sutherland Timber our Sawmilling process consists of the following:

  • A Log Yard for sorting, grading and storing logs.
  • A Morbark 636 Rosser Head De-barker for peeling logs fit for the sawmilling process.
  • We run a Bandsaw Carriage Mill, a 60” Isles forge Bandsaw with a Southern Cross 3 knee carriage and a CM&E slabber.
  • From here the flitchers go through a Salem 4 saw Edger through to the run over docking system where anything that needs to be re-cut goes back to the re-saw - another 60” Isles forge rig.
  • Anti-sap treatment and sorting happens at the round table.
  • All log residues – sawdust, bark and chip – are sold for landscaping, fuel or further processing proving the industry reuses as much product as it can.

Drying Process

How we dry it

  • We have a 4.25MW Vekos wood fired boiler.
  • Our dry shavings are cycled to the fuel bin where they are fed into the boiler.
  • We also chip off-cuts and waste wood when required to keep the boiler fired.

  • We have 3 medium temperature kilns:
    • 1 x 12m Foggarty
    • 1 x 12 Windsor

Cutting, Splitting and Resizing

How we cut it

  • We have a dry shed/planer mill on-site.
  • Our planer is a 300n Wienig capable of running product as big as 300mm x 100mm and of speeds up to 100m per minute.
  • Our planer produces a quality finish, and a twin stenner re-saw for further cutting, splitting and resizing timber.

Our products are wrapped for dispatch.

  • Our Treatment Plant is 13.6 metre 1500 diameter tube with Boron treatment for H1.2 and CCA for H3.2, H4 and H5 levels.
