The Hierapolis sawmill, a water-powered stone sawmill at Hierapolis, Asia Minor (modern-day Turkey, then part of the Roman Empire), dating to the second half of the 3rd century, is the earliest known sawmill.
When was the circular sawmill invented?
1813
Who invented the portable sawmill?
The exciting story of the Peterson family business started over 30 years ago in 1989, when Carl Peterson sold his first portable swingblade mill. Even though it was only a basic version, it was a true invention the world's first commercially available portable swingblade sawmill!23 Jan 2019
How did an old sawmill work?
Early sawmills simply adapted the whipsaw to mechanical power, generally driven by a water wheel to speed up the process. The circular motion of the wheel was changed to back-and-forth motion of the saw blade by a connecting rod known as a pitman arm (thus introducing a term used in many mechanical applications).
How does a sawmill work?
A sawmill works by cutting logs into lumber using large bandsaw blades. The same process is repeated over and over, log by log, to produce high-volumes of rough cut lumber. This process will vary slightly from sawmill to sawmill.
What is a sawmill powered by?
Decades ago, most sawmills used steam power, so they required a dependable and renewable water source. They also added value by using water as a log transportation tool and stored logs in rivers or lakes to prevent stored wood from drying out. Today, steam power is gone, but land is in high demand.
How does a wind sawmill work?
Logs can be brought to the mill by water and then hauled to the saws by wind power. The mill has three saws and each can be fitted with multiple blades. A log can be turned into planks in one pass through a saw. If the planks are passed through again posts are produced.6 Jun 2012
What is sawmill production?
Sawmilling lumber is a throughput process where a raw or rough log starts a journey through mechanized steps and emerges as a smooth finished product. Modern sawmills operate as an on-demand, pull-through system with the mechanized mill parts sitting between the front end loggers and the tail end marketplace.
Is saw mill is a factory?
A sawmill is a factory in which wood from trees is sawn into long flat pieces.
What type of industry is a sawmill?
Today's sawmills are therefore defined as industrial sawing facilities that are of primary wood processing industries.2 Oct 2016
How is lumber made in sawmill factory?
During felling, the trees are cut down with chain saws and the limbs are removed. At the mill, the logs are debarked and bucked, or cut to a predetermined length. Then they proceed to the bandsaw for further processing.
How much electricity does a sawmill use?
Survey responses from 58 Appalachian hardwood sawmills revealed that the electricity consumed per month per mill averaged 220 kWh/MBF, and the average electric bill was $17.78/MBF/mo. Many opportunities exist for sawmills to reduce energy costs and waste in their lumber production.1 Jan 2012
How does a sawmill run?
In some sawmills, the conveyor is a stationary carriage, and the head rig moves its blades lengthwise through the log. Other sawmills have fixed head rigs. They move the log on a mobile conveyor. No matter which system, most modern sawmills use bandsaw blades in their head rigs.
How were the first sawmills powered?
The earliest sawmills, including this one, used “up-and-down saws.” Powered by belts driven by water power, the saw was set up to move up and down as it sawed through a log pushed to it by other water-driven machinery.16 Jun 2011
