For nearly 50 years, AJD Forest Products has been producing top quality industrial lumber for the Lake States region. Located in Grayling, Mich., the company has earned a reputation for supplying high-grade red oak, hard & soft maple, aspen, ash, and basswood.  The mill processes 1,700-2,000 logs, or 70,000-90,000 board feet of lumber a day, but constant maintenance and adjustment on their stacker and chain conveyor brakes were forcing unplanned downtime.
