Lucidyne has completed five GradeScan installations for Weyerhaeuser with systems in British Columbia, Alberta,
and North Carolina. The BC application required GradeScan to integrate information from a Metrigard CLT
machine and an NMI moisture sensor to grade MSR and Dimension lumber. The mill processes SPF species and requires
the scanner to process lumber at speeds up to approximately 2250 feet/minute.
The Grande Prairie, Alberta, installation currently operates at speeds
up to 3000 ft/min; plans are for it to operate at 3600 with bursts to 4000 feet/minute!
This plant processes SPF Dimension lumber and is configured to generate huge volumes of graded lumber
and graded trim blocks. A second scanner was installed in Weyerhaeuser's Drayton Valley, Alberta,
mill at the same time and operates 2600 feet/minute.
The Plymouth, NC installation required integration of an existing Newnes XLG and NMI moisture
sensor with GradeScan to grade Southern Yellow Pine for Dimension and MSR/MEL.
The Greenville mill uses GradeScan along with an NMI moisture sensor for Dimension grading
their Pine. Both mills' trimming and sorting of the lumber is controlled by Lucidyne's
Trimmer/Sorter Control System.
