certain applications it will easily fi ll a 45 ft van in less than 10 minutes. The 3590XL is a 36 in diameter capacity machine with a 36 x 48 in chipper opening and an extremely powerful feed system. The 3590XL can fi ll a 45 ft van in about six minutes. Any of Banditʼs Beast Recyclers can now be converted to a chipper to produce a conventional screened chip utilizing the patent-pending Beast Knife System. As a whole tree chipper, the Beast will effectively chip large diameter material and is an excellent unit for logging slash and sawmill waste. In addition, the knife life in the Beast is actually better than the knife life in a whole tree chipper. If material is too contaminated to chip, you can simply switch to carbide cutting and grinding tools and then switch back to the knives in a cleaner material, lowering the fuel consumption and operating costs. www.banditchippers.com BRUKS CHIPS ON THE GO Four swappable rotors may be just what todayʼs biomass contractor needs. Dumping into waiting containers is a key element to these systems in Sweden. This forwarder mounted chipper turns logging residues to biomass where you need it. Logging slash can be piled up at the edge of the logging area, or for smaller jobs, the machine can go get it. The chipper is installed on a forwarder with crane for effi cient feeding into the chipper. A spiked drum feeds the material to a chipper drum with two exchangeable knives, chipping the material against an anvil. The two chipping knives are changed daily. The chipper drumʼs 1,000 rpm give a uniform infeed and high capacity. It is powered by a Scania 12 litre, 450 hp industrial engine. BRUKS manufactures about 40 mobile chippers per year, and today there are a total of some 150 professional forwarder mounted chippers operating in Sweden. The computerised control system is making it easy to troubleshoot and follow up production, and is handled by the operator via a touch-screen in the forwarder cab. Wood chips are thrown out of the rotorʼs chip pockets to a chip accelerator and through the turnable chip tube into a chip bin. The chipper produces 30 to 50 tons/h of chips when used to its full capacity. In operation over a longer period of time, an average of some 20 ton/hr is realistic. When the chip bin is full, the forwarder moves to a container waiting by the forest road to dump the chips into. These are picked up by a fl eet of tractor trailers. These logistics are important for the effi cient handling of chips. The trucks leave behind empty containers to allow hot logging operations to continue. The chipping operation continues more or less day and night, all year round. The demand for fuel chips to produce power and heat in Sweden is steadily growing. www.bruks.com 24 CanadianBIOMASS Who knows where the future of biomass contracting lies? Not us, and not CBI. Thatʼs why theyʼve made the Magnum Force 6400 to be what they call the worldʼs most versatile grinder. With four different, fi eld-swappable rotors (forged drum ro- tor; solid steel rotor; and two application specific drum chipper rotors), in a single day you can go from making mulch from trees and stumps, to chipping stem wood into 2-30 mm fi ber length, to grinding highly contaminated C&D or railroad ties with the tie plates attached. Features 765 – 1050 hp diesel or electric engine and is 2.99 meters wide to meet European standards. Track-mounted, wheel-mounted and stationary versions available. CBI has a revolutionary chipping process that can deliver uniform 3mm - 6mm micro-chips in a single pass. Traditionally, pellet manufacturers used sawdust when it was available. But as sawdust becomes scarce due to the popularity of this fuel, they have turned to whole tree chips (approximately 30mm in size) and they put them through a time-consuming and costly process of grinding in order to prepare the material for the pellet press. But CBI chippers like the Magnum Force 6400 and the Magnum Chipper 8400 yield uniform micro-chips that can bypass those processes and immediately be dried and milled into feed stock for the pellet press – saving up to 75% of the input power requirement while increasing the pellet press throughput. www.cbi-inc.com CW’S PLUG & PAY GRINDERS CBI HAS FLEXIBLE STRENGTH Savings can be substantial with a grinder plugged into the grid. As the cost of diesel fuel has increased, electric powered wood grinders have become the grinder of choice for an increasing number of grinding professionals. DECEMBER 2008
