Park Falls Site
Located within the city limits of Park Falls, Wisconsin on Fraser Papers pulp and paper mill site, this modern facility is located on 35 acres with rail service and wood yard storage of 85,000 cords (see map). Wood is purchased by the stick scaled cord.
Principle structures include scale office, maintenance building, and manufacturing facility with office, and essential employee and maintenance facilities. The plant has the capability to ship and receive wood 365 days per year.
Built in 2002 the mill was designed by Johnson Timber, in cooperation with Dingwells Machinery of North America and Automation Now of Thunder Bay, Ontario to specifically match the production and quality needs required of this unique pulp mill. Contract signing occurred in August 2001 with production beginning in March 2002.
Summit Lake Timber procures 115,000 cords of white birch per year. The wood is then stored and aged for 12 months prior to recovery and processing into chips. This process concentrates the sugars within the fiber while decreasing the pitch content. Summit Lake Timber assumes all cost of procurement, aging, processing and delivery of chips to the pulp mills storage silos. The pulp mill is billed weekly for chip deliveries on a bone dry ton basis.
The chip mill is comprised of 3 main components:
1) Debarking is accomplished using a 60’, three rotor Deal Processor rotary debarker. Rotary debarking allows multiple stem wood on wood debarking in conjunction with mechanical abraders allowing >.5% bark content during winter conditions without deicing costs. In the first 24 months (start up to date of this report) of operation an average bark content of .3% and a fiber yield increase of 2.5% over the previous wood room has been attained.
2) Chipping is performed by a 104” Carthage 15 knife, drop feed chipper equipped with Key Knife’s latest system including knife holder mounted ribbon breakers and driven by a 1,200 horse power synchronous motor.
3) The chip delivery system includes 4 additional days of chip storage and a 2,300 foot conveyor system linking the chip mill with the pulp mill storage silo’s.
The chip mill generally operates on a 12-hour day production schedule. One employee located in an operators cab (outfitted with camera monitors and a panel mate control station) performs adjustments to production flows.
