A schematic figure of a stone grinder. Another type of mechanical pulp is refiner pulp. In this method, chips are fed into the centre of two refining discs, Figure1.3 One, or both, discs rotate whereby the chips are reduced in chips and fibres abraded off. The disks are grooved, coarser grooves near the centre and finer toward the perimeter.

The Paperboard Process - Iggesund

Mechanical Pulp. Refiner mechanical pulp (RMP) is a two-stage process in which the debarked logs are first converted into small flat chips. These chips, with a moisture content of 25–30%, are forced between the rotating metal discs of a refining machine. The heat and water vapour generated soften the lignin so the fibres can be separated.
