Get the most out of the wood you put into the process

To reach sustainability targets, you need to utilize and save raw materials in the most cost-effective way. Chip quality is a really important factor affecting quality and total economy in the whole pulp, paper, board and fiberboard making process.

The key to high quality chips

The condition of your chipper is a key to the production of high-quality chips. 
Your chipper chips hundreds of thousands of tons of logs annually and during that time abrasion of the chipper disc, chipper knife equipment, spout, casing is very high. Chipper function and condition test provides information about the present state of your chipper and serves as a basis for proposals for improvements.

Custom-made chip quality optimization Chip quality agreements (ChipQ)

Valmet provides custom-made Chip Quality Agreements (ChipQ) depending on customer’s process equipment and requirements. The process starts with wood receiving and covers debarking, chipping, storage, and screening. The primary target of the optimization is even chip quality and minimized wood losses. Valmet will help to achieve optimum quality while providing the tools for optimizing your process and production economy.

Reduces wood losses from screening and debarking

  • Reduces 0-mass production and chemical/energy consumption (lower fines content)
  • Reduced wood consumption
  • Reduces raw material-based downtime in the whole mill
  • Enables more uniform chip thickness and therefore more uniform end product quality – lower variation
