Chipping
Valmet chippers for superior chip quality, higher yield, and lower operating costs
With more than 2000 heavy duty chippers delivered worldwide—half of all disc chippers in the fiber processing industry—Valmet is the global leader in chipping technology. Our equipment is built on over 200 years of engineering heritage from Rauma, Carthage, Murray and Demuth, incorporating patented features and proven design advantages that deliver superior chip quality, exceptional durability, and easy, safe maintenance.
Superior chip quality
Chip quality is the most important factor affecting pulp quality and the total economy of the pulp mill
High capacity
Smooth log infeed, the widest infeed spouts and a high number of knives deliver maximum output
Excellent durability
Heavy duty design for a long operational lifetime and the strongest knife discs available on the market
Safe and easy maintenance
Designed for the real world with excellent accessibility, fast knife changes with special tools and minimal downtime
Chip quality at the heart of wood handling process
The chipper is the heart of the wood handling process, ensuring high quality chips through precise chipping geometry, advanced knife design, and optimized log control. These features minimize wood losses and secure a high share of uniform, acceptable chips. High capacity performance is further supported by an even log feed rate, a wide infeed spout, and a large number of knives, all engineered by Valmet to deliver superior chip quality. Valmet’s disc chippers combine extremely durable, heavy duty construction with the strongest knife discs on the market, enabling smooth, reliable operation with minimal maintenance needs.
Superior chip quality for high-capacity chipping lines
Valmet Disc Chipper Camura HGS
The horizontal-feed HGS chipper sets a new standard for high-capacity chipping, consistently delivering superior chip quality. The chipper features one of the widest infeed spouts on the market, engineered to handle multiple logs efficiently. The spout dimensions give both extra width and height essential for high capacities with both small and large logs, while significantly reducing the risk of log jams. The ingenious spout design ensures precise log guidance and optimal chipping performance—even with a single log.
High-capacity chipping for tree-length logs
Valmet Disc Chipper Carthage
The horizontal-feed Carthage chipper is designed for high-capacity, tree-length log lines. Its robust design ensures reliable performance and consistently high chip quality. A wide infeed spout supports high capacity, and two bed knives provide a larger, more stable cutting area for efficient and accurate chipping.
High-capacity and reliable performance across wide range of log sizes
Valmet Disc Chipper Camura GS
The drop-feed GS chipper is designed for high-capacity chipping lines, delivering reliable performance across a wide range of log sizes and diameters. It is an excellent choice for chipping logs with extra-large diameters. The advanced spout design provides precise log guidance, helping achieve consistently high chip quality by positioning even single logs optimally for chipping.
Optimal performance for medium-capacity chipping lines
Valmet Disc Chipper Camura GSN
The drop-feed GSN chipper is an excellent choice for medium-capacity chipping lines. Its robust, straightforward design ensures reliable operation, optimal chipping performance, and consistent chip quality.
Excellent chipping performance for mixed wood qualities
Valmet Drum Chipper
The drum chipper is especially designed to handle a large variety of wood qualities, combining high capacity with excellent chipping performance. Horizontal feeding ensures safe and trouble-free operation. Robust and simple design results in low maintenance need.
Why chip quality matters?
In pulp production, everything starts with the raw material. But not all chips are equal. That's why the chip quality matters more than you might think.
Uniform wood chips are the foundation for efficient cooking, stable fiber quality, and optimized mill performance. Even small variations in chip size or quality can lead to higher chemical consumption, process disturbances, and reduced end-product quality.
All for the chip
Valmet’s lifecycle commitment improves efficiency and chip quality at pulp mills.
Chip quality has a direct influence on pulping efficiency, yield and raw material costs. While mills cannot control every aspect of raw material variation, they can significantly improve chip uniformity and process stability by focusing on the equipment lifecycle – from original design and modernization to maintenance, process monitoring and long‑term development.
