Mechanical pulping Wikipedia

Mechanical pulping is the process in which wood is separated or defibrated mechanically into pulp for the paper industry.. The mechanical pulping processes use wood in the form of logs or chips that are mechanically processes, by grinding stones (from logs) or in refiners (from chips), to separate the fibers.

Kraft process Wikipedia
