摘要： A housing is equipped with a set of grinding tools and a rotor equipped with a second set of grinding tools. One of the parts carrying the grinding tool set is moveable in relation to the other part, which may be constituted by the rotor, in axial direction of the rotor and can be adjusted by a piston-and-cylinder unit impingeable with a pressurized fluid medium, preferably compressed air. The compressed air infeed into the piston-and-cylinder unit is accomplished by a compensation force regulator controlled as a function of the pressure of the stock suspension within the internal compartment of the housing and a grinding force regulator controlled independently of the compensation force regulator in accordance with a set value signal infed by a control line. The pressure force exerted upon the one moveable part therefore is the resultant of a first force component influenced by the compensation force regulator and corresponding to a compensation force which compensates the pressure force of the stock suspension and a second force component influenced by the grinding force regulator and adjustable in accordance with a predetermined grinding force. Thus, there prevails a substantially constant grinding load which is practically independent of possible changes of the stock suspension pressure within the housing.

摘要： A device for cleaning a suspension, preferably a fibrous suspension for paper production. The device includes a screen basket, on the exterior surface of which the suspension to be cleaned is supplied and from the interior surface of which the screened accepted stock is released. A housing surrounds the screen basket. The housing includes an inflow for the suspension to be cleaned, an accepted-stock outlet for the cleaned suspension and a reject outlet for impurities. A scraping device rotates on the outside of the screen basket about the screen basket axis and has scraper blades (foils) which scrape along the exterior surface of the screen basket. The scraping device comprises a drum with a cylinder surrounding the screen basket. The cylinder carries a plurality of foils on its inside facing the screen basket.
