Chipping

The chipper is the heart of the wood handling process and plays a major role in maximizing the amount of high-quality chips for digesting. Correct chipping geometry and knife design are essential in minimizing wood losses and maximizing the amount of accepts. Another important factor affecting chip quality is the optimized control of logs and stable chipping in the direction of the fiber. The main factors in high capacity chipping are an even log feed rate, a wide infeed spout and a large number of knives.

The Valmet Disc Chipper has one of the widest infeed spout on the market, especially designed for multiple log chipping. The spout dimensions give both the extra width and height essential for high capacities with small or large logs and for the reduction of log jams. The ingenious spout design also ensures perfect log guidance for optimum chipping even with a single log.
