Logging and Sawmilling Journal November 2013

February 2014

On the Cover:
The B.C.-based Ledcor Group, which is well known as one of North America’s leading construction companies, is now in the sawmilling business, with a new multi-million dollar mill in Chilliwack, B.C., east of Vancouver. The Chilliwack mill processes low-end logs primarily from the B.C. Interior, manufacturing multi-dimensional cants, and lumber (Photo of new Ledcor mill by Paul MacDonald).

Alberta’s beetle battle working
Alberta’s quick response approach—along with forest companies putting a priority on harvesting areas infected with the mountain pine beetle—is working, and maintaining a high level of control of the beetle in the province.

Log hauling pioneer
B.C.’s Shelley Stewart is kind of a pioneer in the forest industry; having started a successful log hauling operation that now has eight trucks, she’s helping break the gender barrier in the industry.

COFI Convention in April
The Council of Forest Industries (COFI) convention is Western Canada’s premiere forest products convention, and will be held on the shores of Lake Okanagan this year, in Kelowna, April 2-3. The convention promises to offer something for everyone, from top notch speakers to industry displays.

Ledcor moving into lumber manufacturing
Ledcor Resources and Transportation has moved into producing solid wood products with a new $18 million sawmill in Chilliwack, B.C. that takes low-end logs and manufactures multi-dimensional cants, and lumber.

Timber revenue being plowed back into the community
A community forest in Terrace, B.C. is helping to support local sawmillers and add value to the productive forest, at the same time generating funds that are plowed back into the community.

Steep slope specialist
Logging contractor Blair Schiller is a veteran of steep slope logging, working in the Monashee Mountain Range around Revelstoke, B.C. using a variety of equipment including a used Washington 88 grapple yarder which—after a bit of work in Schiller’s shop—is earning its keep.

Volvo equipment dealing with Tembec’s tough temperatures
Tembec’s Cochrane sawmill operation had a wide choice when it came to choosing a new wheel loader, and in opting for a Volvo L120G machine they have a piece of equipment that is delivering reliability in the polar vortex-type temperatures of northern Ontario.

All in the family
Having taken over the family logging firm from their father, Dave and Kevin Roberts have now ramped up their harvesting activities—and their equipment line-up—to meet the needs of Canfor’s newly modernized mill in Elko, B.C.

The Edge
Included in The Edge, Canada’s leading publication on research in the forest industry, are stories from the Canadian Wood Fibre Centre, Alberta Innovates - Bio Solutions and Alberta Agriculture and Rural Development.

The Last Word
The future is bright for the B.C. Interior forest industry—but clouds, such as the drop in the timber harvest due to the mountain pine beetle, need to be weathered first, says Jim Stirling

TECHUPDATE - Primary Mill Breakdown Equipment

By Tony Kryzanowski

USNRUSNR

Designed for small log, single-pass requirements, USNR’s SL3000 Small Log Processor integrates advanced mechanical, optimization, and control technologies to produce a high yield of ready-to-trim lumber and quality chips.

The SL3000 combines true shape scanning, controlled log transport, profile chipping, and curve sawing in a compact system. This configuration makes it possible to produce a wide variety of products in a single process, maximizing recovery of volume and value.

True shape scanners provide real-time optimization solutions displayed in 3D graphics on a Windows interface. Operators easily select grade inputs and choose full taper, split taper or variable taper solutions. The optimizer quickly generates multi-sawing and profile solutions.

The SL3000 is a well-engineered, high quality machine designed to maximize both value and volume recovery, says the company. USNR also offers log processors for larger logs and higher speeds to produce a broad range of products.

OptimilOptimil

In business since 1984, Optimil has developed a full line of small log chipping canters. Its design team is constantly working to increase feed rates with more accurate lumber sizing. The small log canters of today can operate in excess of 750 FPM.

The Optimil Small Log Profile module can be incorporated into the chipping section or remotely mounted downstream on new and existing vertical arbor gangs. These profilers help to reduce the number of flitches going to the board edger, while maintaining accurately sized lumber.

Optimil’s close relationship with its customers has led the company to focus on sawdust and chip containment over the last several years. It has developed and manufactured a new chipping canter that is helping to reduce the number of stray chips and sawdust escaping in to the mill air. These have been developed with consideration for accessibility, maintenance and safety.

Optimil can provide high production through a new machine or updates to an existing machine.

ComactComact

Comact has introduced its edging module for primary breakdown.

This piece of equipment has been in operation at Quebec sawmill Scierie Dion since 2011. It allows immediate edging right on the log without compromising product output by twin band saws. Moreover, thanks to tools developed and tested for accurate log positioning, Comact clients are ensured of highly accurate edging/profiling of lateral products right on the logs.

HewSawHewSaw

HewSaw is a leader in the design and manufacturing of single pass primary breakdown lines and machines for sawn timber. This family-run company, which is based in Mäntyharju in the heart of the Finnish Lake District, is celebrating its 50th Anniversary in 2014 and has sold over 70 machines in North America and more than 350 around the globe.

In North America, HewSaw offers its “R” Series single pass machines which, depending on the model, can process logs up to 20” in diameter. Its “SL” lines, which feature multiple in-line units, can process logs up to 21.5” in diameter.

All HewSaw models are capable of producing edged sideboards while processing dimension and stud products from the centre cant, with the SL lines offering the most flexibility in output options. HewSaws are designed to maximize production volumes and recovery, while creating a safe, clean, quiet and ergonomically designed work environment.

LinckLINCK GmbH

The LDK Igirma sawmill belonging to the Russian Timber Group is a milestone for the development of the Siberian sawmill industry, says equipment manufacturer LINCK, a supplier to the mill.

The line begins with two large LINCK VM 50 canters, powered up with 320 kW each.

Within the profiler unit, wane is removed from the two sideboards produced at that stage. The profiler heads are adjusted vertically and horizontally with servo cylinders.

Based on the data provided by the upstream 3D scanner, the profiling heads will operate along the pre-planned cant in order to achieve nothing less than the most efficient solution provided by the optimizer, says LINCK. The sideboards, produced on the fly in the best possible way, are then removed from the centre cant by the CSMK DAG.

The line can work at speeds of 150 m/min (500’/min).

The plant is equipped with the latest optimization technology, allowing the proper decision to be taken for each individual log on how it should be sawn: straight, centered, diagonal alignment, or curve sawing.

Soderhamm ErikssonSöderhamn Eriksson

Since the mid-1990s, Söderhamn Eriksson, together with leading suppliers of measuring and optimizing equipment—such as MPM in Canada—have together delivered saw lines with the highest sawing yield available on the market, says the company.

The company’s primary breakdown equipment includes a rotating log turner which provides the best position for the log to be sawn. After logs are precisely positioned and 3D-scanned for optimal yield, they are then handled by the company’s LogPos, which always gives the correct alignment. They are then fed through a chipper canter equipped with the company’s newest chipping heads, the CombiCut. The cants are then processed through the AKE Sawmaster twin or quad arrangement. The Sawmaster can be equipped with Vision Tilt, which provides full band saw control for best performance and highest profitability.

For small log lines, the company’s band saws can be replaced with one of its Eurosaw circular saw machines; these saw lines increase sawing yield. The mill’s total capacity, accuracy and versatility will be improved, says the company.
