This is Bill Chamberlain of
Soderhamn Eriksson.
I am pleased to advise you about the Bruks Klockner market in Europe, which at this time is very active in Energy from Wood.
As you will recall from the Ligna exhibition in 2005, we had on display the Largest Drum Chipper in the World, that 2.8 metre diameter rotor is now churning away at Hallein Pulp Mill near Saltzburg in Austria, where it was installed last October.
The machine is chipping logs up to 1.3 metres in diameter, solely for energy production.
Also at Hallein we have installed the latest version of the Tubulator Conveyor, which has enclosed
(airslide) return, thereby making it even cleaner than its predecessor and requiring less maintenance.
The longest Tubulator in Europe is now almost 300 metres.
From Poland, Kronospan have ordered a chipper with 2.0 metre diameter drum for their plant at Sczecinek, that machine is currently in production at our factory in Hirtscheid.
Kronospan in Russia at their Ergojewsk plant have ordered Tubulators of approximately 600 metres in total, they are all manufactured at Arbrå in Sweden.
In Great Britain we have taken our first two energy plant orders, the first for SembCorp in Middlesborough, that is a line consisting of a log-deck, chipper infeed conveyor with cleaning station, a 1.6 metre diameter rotor chipper, with outfeed distribution to storage for blending with recycled wood chips and short rotation coppice.
The second energy plant order is for our largest British customer, A W Jenkinson, who were featured in the BK brochure some three years ago.
This plant is significantly larger as it includes a 2.0 metre diameter rotor chipper, along with log infeed station, recycled wood infeed via a dumping pit and into a the chip storage area. The distribution method will be from a plough passing along a belt conveyor, it being the first in the UK.
From the storage area the chips will be discharged into two walking floors, where they will be passed over two disc screens, with oversize chips going through a BK hammer mill. From the screening station the chips will go to a Siemens / Kvaerner boiler for electricity production.
Similar lines can be seen in Hungary and Southern Italy, but the most significant benefit of this site is that there exists two sawmills from where chips will also be imported, potentially by Tubulator Conveyors directly into the energy plant fuel storage area.
During the pre-Christmas and post-Christmas period we also installed a complete recycling line for
A W Jenkinson at their Bo’ness site in Mid-Scotland.
That line consists of a 400 x 1200 Horizontal Feed Drum Chipper with 250 kW main drive motor, but instead of a standard knife drum, it is fitted with a hammer rotor for shredding pre-crushed pallets and other recycled wood residues.
The components in the line include a dosing table that feeds onto a vibrating conveyor, under an
over-band magnet and into the horizontal shredder. From there it is conveyed via a chain scraper with drum magnet, to remove finer metal contaminates and onto a BK-SF 10 free standing chip screen, which is installed parallel to the existing installation from 1998.
Another market where we have seen development is in processing bark, such as at A W Jenkinson in Northern England and most recently an extension to the screening line at Westland Horticulture in Ireland.
The installation at Westland includes a 4 m x 5 m dosing table that steadily loads the raw bark into a vibrating conveyor, feeding through a trommel screen, then into a drop-feed chipper before final grading over a double decked BK-SF 12, which grades the chipped bark.
In Southern Ireland we have supplied three BK-SH 8 Free-swinging Screens in-line to grade pre-crushed bark into three fractions of + 50 mm, + 25 mm and minus 10 mm.
The third market we have seen developing is High Value Animal Bedding, being processed from recycled wood.
A company known as G I Hadfield of Manchester, manufacture a product named
"Easibed".
"Easibed" is manufactured from pallets and other wood waste, it is first shredded then carefully screened and cleaned.
The pre-shredded and cleaned material is then loaded onto a 4 m x 5 m dosing table, discharged into a climbing chain scraper conveyor and into a distributing screw auger, where, on demand, it feeds two
BK-MB Beating Flakers when the material is further processed into the finished product.
From the beating flakers, the chips pass over a BK-SF 12 chip screen to separate the dust from the animal bedding.
The wood industry is opening up other markets, particularly for recycled material and we are constantly monitoring those potential
developments.
