This is how the sawmill works
Around 55 timber trucks with spruce and lodgepole pine roll in here every day. Come along to the sawmill and see how logs are turned into boards and planks.
1. Measuring station
In order to keep production up, approximately 2,000 m3fub (cubic meters solid under bark) of timber is required every day, year around. This corresponds to approximately around 55 timber trucks. The timber is camera-measured automatically for volume and quality by Biometria before it is placed in unsorted rollers. The wood is then sorted according to quality and size and placed in smaller piles according to the top diameter of the log.
2. The saw
Timber graded logs from the measuring station are placed on the saw bench before it goes through the bark machine. The timber is debarked and passed through a measuring frame that scans the dimension and top diameter of the log. The logs are measured in a three-dimensional measuring frame that calculates the maximum yield of each log. To further maximize the yield of the raw material, the cutters move vertically to optimize each log and make different widths on each board.
3. Raw sorting
Planks and boards are sorted according to different dimensions, in different compartments. Then they are strewn with drying straw between each layer of boards so that air can pass between the boards in the dryers.
Depending on thickness and width, or moisture content between 12 and 20 percent, the packages are placed in different kilns that are heated to around 60 degrees Celsius and dried for an average of four days. The kilns are heated by burning the bark from the debarking.
5. Grading mill
With the latest camera technology the planks are sorted and adjusted according to quality and length with speeds up to 140 planks a minute. The new camera sorting increases the value exchange because it "sees" much better than the previous one. We also sort construction timber for the construction trade. After the cameras, the pieces are cut in the trimmer to the predetermined lengths. After that, the sawn timber is packaged as a finished product for delivery to the end customer.
Sawn timber is loaded onto trucks for transport to the end customer. The products are delivered both locally and globally. We have customers all over the world and load over 5,500 truckloads of finished products per year.
