Main Sawmill

A main sawmill is a central or primary facility in a lumber production operation. It is typically the largest and most comprehensively equipped sawmill within a network of smaller or more specialized sawmills. The main sawmill is responsible for processing the majority of the raw logs harvested from forests into various lumber products.

The functions of a main sawmill often include:

• Log Reception and Sorting: Receiving harvested logs, sorting them by species, size, and quality, and storing them in log yards.

• Debarking: Removing the bark from logs to improve the efficiency of sawing and reduce wear on saw blades.

• Primary Breakdown: Using large saws, such as band saws or circular saws, to break down the logs into cants (large squared timbers) or flitches (thick slabs).

• Secondary Breakdown: Resawing the cants and flitches into smaller, more standard lumber dimensions using a variety of saws, including gang saws, edgers, and trimmers.

• Grading and Sorting: Evaluating the lumber for quality, defects, and dimensions and sorting it into different grades.

• Drying: Reducing the moisture content of the lumber through air drying or kiln drying to improve its stability and prevent warping or decay.

• Planing (Optional): Smoothing the surface of the lumber to achieve a more uniform and aesthetically pleasing appearance.

• Shipping: Preparing the finished lumber for shipment to wholesalers, retailers, or construction sites.

Main sawmills often employ a large workforce and utilize advanced technology, such as computerized saw controls and automated lumber handling systems, to maximize efficiency and minimize waste. Their output significantly impacts the regional and national lumber supply.
