摘要： 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.

摘要： A method and apparatus for hydraulically transporting objects, including particulate material such as coal, along a conduit. A supporting material such as a quantity of flexible fibres are mixed into a liquid and their tendency to flocculate therein is utilized to create a network which will support the objects in the liquid. The objects can be supported in the mix while it is pumped along a conduit, for example a pipe, to thus transport the objects. At the outlet a separation means removes the objects from the mix of liquid and supporting material.

摘要： Large or small articles are hydraulically transported through a pipeline with the help of fibers that flocculate in the hydraulic liquid to form flocs and networks of flocs which cushion the articles against engagement with the wall of the pipeline pipe. The articles can be packed in capsules and the capsules provided with vanes to improve cushioning. Cushioning can also be improved by introducing stranded lattices into the fiber-floc-containing liquid to thus increase the flocculating action.
