Tech Update - Debarkers

Valon KoneValon Kone

Valon Kone (VK) is one of the leading manufacturers of high-speed ring debarkers, and a global company that specializes in the development and production of rotor debarkers.

VK’s extensive selection means that customers are sure to find a suitable machine for any debarking situation, regardless of wood type.

In North America, Valon Kone offers the Kodiak high-speed ring debarker. This model was specifically designed for the rugged North American market and offers exceptional uptime, debarking quality and low operating cost, says the company. State of the art safety features are also incorporated to suit North American requirements. Recent improvements have concentrated on dust control to suit Class II, Div II requirements, increased feed speeds and increased uptime. Rotor designs now offer oil collection systems.

Valon Kone now also offers the Variable Flare Reducing rotor (VFR) for automatic variable flare reducing on all debarker diameter ranges.

Valon KoneUSNR

USNR’s modular CamShift debarking system can be delivered with or without flare reducing, and with one or two debarking rotors.

CamShift has three rotor size options for feed speeds up to 130 m/min (425 ft/min) with one debarking rotor, and up to 150 m/min (490 ft/min) with two debarking rotors.

The CamShift 600 offers both log releasing tools and tool pressure adjustment during operation. The manually adjusted flare reducer rotor is infinitely adjustable for reduced diameters to 560 mm (22”). The pull-out design makes for easy set up and tool changes. Variations accommodate minimum log length and top-end or butt-end feeding.

USNR also manufactures a full range of Cambio debarkers to meet species and piece count requirements from minimum log diameters of 65 mm (2.5”) to a maximum of 795 mm (31”). The company’s debarkers get the job done on frozen logs, wavy logs, high value hardwood and high volume softwood logs, says USNR.

Kadant FujKingKadant Fuji King

Kadant Carmanah has been a leader in rotary debarking since first introducing the Fuji King debarker to North America 25 years ago.

The technology was initially developed to process fibre materials not suitable for ring or drum debarking. The ability to effectively process a wide range of species, shapes and sizes with varying moisture content and temperature elevated rotary debarking as a preferred choice by operators worldwide. Over 275 machines have been sold to oriented strandboard and pulpwood rooms, sawmills and pellet plants globally, many operating 24/7 in very tough conditions.

The Fuji King closed-bottom design differs from other rotary technologies, ensuring the highest fibre retention and reduced operational and maintenance costs, says the company. Bolt-on replaceable debarking blocks allow operators to quickly and cost effectively adjust the debarker’s aggressiveness to suit changes in wood conditions. This flexibility ensures that bark and fibre loss targets can be met year ‘round in all conditions.

Valon KoneDK-SPEC

The DK-SPEC debarker conversion is an excellent business decision, says the company. This is a key contributor to the production and optimization of wood product facilities. DK-SPEC’s rebuilt debarkers improve on mechanical reliability and speed at up to 400 ft/min.

Existing debarkers are rebuilt to new condition, the rotor is changed to new air bag technology and DK-SPEC can also convert to electric drive. Throughout the years, the company has successfully converted many 18”, 24” and 30” debarkers.

DK-SPEC is also said to be an excellent partner for debarker support. It has a large inventory of debarker parts and offers repair and overhaul service for debarker components and rotors.

Logging and Sawmilling Journal
August/September 2017

On the Cover:
The Princeton, B.C. sawmill of Weyerhaeuser Canada has seen some major equipment upgrades in the last few years—but there is more to come, as the sawmill continues its efforts to make operations more efficient, and reduce costs. The two-line sawmill in the B.C. Interior turns out upwards of 300 million board feet of SPF lumber annually, and is undergoing a multi-year upgrade (Cover photo by Paul MacDonald).

Working to keep the risks of Climate Warming at bay
Warming climates up the risk of forest fires, and one community forest, in Burns Lake, B.C., is implementing a fire mitigation project that will help protect the town’s forest industry—and social assets.

Combo mill upgrade project
The Gilbert Smith Forest Products sawmill in Barriere, B.C. recently completed a lumber grading/sorting project that combines the lumber flow from the mill and planer through the same system, which required a good amount of ingenuity and resourcefulness since it involved combining new and used equipment.

Alberta forest industry update
Just in time for the Alberta Forest Products Association AGM in Jasper, Logging and Sawmilling Journal takes a look at what’s going on in the Alberta forest industry, and how the industry is dealing with the duties on lumber going to the industry’s #1 customer: the U.S.

Great equipment fit in the Gaspé
A new Ponsse ScorpionKing harvester is proving to be a great fit for brothers Jean François and Steve Lemieux, and their harvesting operation in Quebec’s Gaspé Region.
