Fluff cellulose pulp was oven-dried overnight before grinding. A known quantity of the dried fluff pulp was taken and ground one to three times through a laboratory heavy-duty knife mill (Retsch SM 2000, Germany) with a 0.25 mm screen. The knife mill consisted of a cutting blade rotor (1690 rpm, 60 Hz) which was powered by a 1.5 kW electric motor.

Here the steam and volatile materials are tubed off. After that, this cooked pulp is returned to the chemical recovery cycle. Fiber separation in mechanical pulping is less dramatic. Debarked logs are forced against rotating stone grinding wheels in the stone ground-wood procedure. Refiner pulp and thermo-mechanical pulp are produced by chips.
