Webwater. A recent development in mechanical pulping involves shredding and grinding chip of wood between the rotating discs of a device called a refiner. The product of this process is known as refiner mechanical pulp (RMP). RMP usually retains more long fibers than stone groundwood and yields stronger paper. Most new installations now employ thermal WebExplanation: In the 1950s, the refiner mechanical pulping (RMP) process was developed, which produced a stronger pulp and utilized various supplies of wood chips, sawmill residues and sawdust. RMP results in more long fibers than stone groundwood and subsequently stronger paper. However, the energy requirements of RMP are higher and …

WebRefiner Mechanical Pulps (RMP, Thermo-Mechanical Pulps = TMP) are produced by defiberizing wood chips between disc refiners. The elements causing the mechanical action – grits on a pulp stone in the grinder and bar edges on a steel disc in the refiner – will give the resulting pulps a typical blend of fibers and fiber fragments. WebThere are essentially three types of refiners used to make mechanical pulps: 1. Single disc: One of the first, still used in new installations. Lowest capital cost has smaller capacities … WebThe various mechanical pulping methods, such as groundwood (GW) and refiner mechanical pulping (RMP), physically tear the cellulose fibres one from another.
