A method and system for separating an aqueous suspension containing fibrous particles into fractions of different average characteristics. The suspension to be separated is supplied to a separator disc rotating in a horizontal plane in the upper part of a chamber, in which collecting means are arranged in different zones to receive material dispersed from the disc. The method and system are effective for the separation of paper pulp suspensions such as groundwood pulp, chemical pulp, sediment or waste paper pulp into fractions of different fibre size and for the cleaning of paper pulp suspensions for impurity particles such as sand, shives and splinters. Another field of application is the separation of mineral wool suspensions into fractions consisting mainly of fibrous and spherical particles, respectively.

A method and apparatus for drying disintegrated fiber mass or paper pulp comprising substantially free single fibers and wads or lumps of fibers. The disintegrated fiber mass is exposed to hot drying air or gas at a temperature of at least 180.degree. C. Free fibers are separated from the fiber mass during or after the drying process in order to avoid or compensate for excessive heating and drying of these free fibers. This facilitates a later grinding process in which the dried fiber mass is ground after addition of water.

A method and an apparatus for producing agglomerated powders such as coffee powder, coffee substitutes such as chicory and other highly hygroscopic and thermoplastic powders in which powder is made to fall down against a central area of a rotating disc. The powder is moistened during the fall against the disc by the supply of steam or finely atomized water across the central area of the disc at such a distance above the same that practically all the powder is moistened before it hits the disc.
