It is designed to deliver large quantities of chips for use as bio-fuel.
The chipper was developed in cooperation with the largest supplier of wood chips in Denmark, Danish forest managing and contracting company, Hededanmark. It allows for an efficient and economical logistic solution to retrieve biomass from the forest and deliver the finished chips at roadside either in stacks or containers ready for road transport. Apart from a larger chip container (20 m3), the Silvatec Grane 8325CH chipper has many new features compared to the previous models. The chipper comes with a large engine (240 kW / 326 hp) for increased transmission torque and traction power, an IQAN control system to control engine, crane and chipper feeding mechanism, larger NAF bogies for increased terrain handling capabilities and 700 tyres to keep ground pressure down.
The Silvatec has been chipping for over 20 years as an efficient, low cost platform for the industrial production of high quality bio-fuel chips for heating plants. The unique benefits are obtained through chipping directly in the forest where the trees have been felled without being delimbed, thus eliminating unnecessary transportation of “empty volume” or losing potentially profitable biomass that would otherwise follow from delimbing and forwarding of logs to roadside chipping locations. Biomass in tree crowns and branches may add up to as much as 25% in extra chip volume with no extra effort.
The advantages of the chipper are that it is efficient and profitable down to low volumes per ha (acre). The handling of chips is much easier than handling trees and reduces driving in the forest. There is better utilization of trees and branches. Finally, chip quality may be improved as the chips can be produced that are below 35% moisture content and the high nutrient tree components remain in the forest (needles and leaves).
