In the wet-mechanical separation of solids according to their density in a separation apparatus by float-sink separation in a centrifugal field of a rotating vessel, difficulties result with variations in the suspension properties and the solids properties in relation to the sharpness of separation and the throughput. As a result of the configuration according to the invention of the separation ap...

A resin reinforced fibre product such as glass fibre impregnated with a thermosetting resin is treated to recover fibre by initially shredding the waste, pulverizing the shredded waste and sieving the pulverized waste to separate the free fibres. The remaining waste is milled to produce a fine powder suitable as a filler. The pulverizing is completed without classification and a portion of the pul...
