A disadvantage of using chips to make pellets is the energy consumption required in the process. Hammer mills are needed to mill the material and it also has to be dried energy intensively.

However, new cutter heads developed by Linck substantially cut the energy required. The heads can be equipped with more chipper knives than existing technology, producing shorter, fine chips. Higher chipper canter power is required, but this is offset by energy savings elsewhere.

Linck has even addressed the matter of seasonal demand for pellets, designing the new cutter head to be easily changed over from producing fine to standard chips.

Short logs

Another new development ties in with the sawmill industry’s need to develop lower capacity, decentralised facilities. Linck’s first new generation machine to meet this trend is the VM35 chipper canter, targeted for use on saw lines for smaller diameter and short logs.

The machine’s cutter head can operate at considerably higher RPM, allowing feed speeds of over 200m/min, and it is also equipped with a separately bedded guide disc. And, despite the speed, says Linck there’s no compromise on sawing accuracy.

The new cutter head has a smaller diameter than its “big brother” equivalent from Linck, which also allows a close-coupled placement of the in/outfeed rollers. As a result VM35 can process a minimum log length of 1200mm with no loss of quality, making it particularly suitable for packaging timber.

The VM35 is also designed to be combined with profiling and saw units.

Linck will be in Hall 27, stand D32.
