Dewatering machines, provided with a pick-up roll, are used particularly for continuous thickening under stabile input conditions. The machine capacity depends on the sort and mainly on the dewatering speed or refining rate of fibrous stock and its input consistency.
Disc deflakers D are designed for deflaking of waste paper, machine broke, chemical pulp and for defibration of knotter-screening pulp and other sorts of rejects from separators. Refiners and deflakers are delivered as single-disc machines with one working zone (sizes D1, D2, D3, DR2, DR3) or as double-disc machines with two working zones (size 2DR3).
Refining and deflaking functional elements are made of special alloyed cast steel. The rotor, cover and working box are made of stainless steel, the sealing body is made of bronze (type D). Stainless steel is with the DR2, DR3 and 2DR3 refiner. Other parts are made of structural steel. All parts coming in contact with the stock are protected against corrosion.
