Carrier to reopen Big River mill with retrofits

Carrier Forest Products Ltd. has contracted with USNR to retrofit its mill operation at Big River, Saskatchewan.

March 28, 2013  By  John Tenpenny

The dimension lumber mill had been mothballed for several years and was subsequently acquired by Carrier from Eacom in 2011.

Improvements in the lumber market heralded the decision to restart the mill. The project is targeted to maximize recovery and throughput, and improve system reliability to bring it up to today’s standards.

According to USNR, the retrofit will consist of optimization software and computer upgrades for the existing lineal gang and edger lines, as well as replacing the obsolete Hydra sensors with USNR’s LPL sensors. The edger’s RoboGuide system will also be upgraded. The sawmill trim/sort line will receive a new Multi-Track Fence and dual articulating smart (drop out) gate, optimization software and computer upgrades, and a WinTally system. The planer line will receive a Lineal High Grader (LHG) automated grading system, Multi-Track Fence, grade projection system and WinTally system. The mill’s large log line, edger, trim/sort and planer lines will all be upgraded with the ControlLogix PLC platform.
