摘要： The process for the production of mineral wool fibres is based on melt streams 1 issuing from a melt distributor 3 being reduced to fibres in a drawing nozzle 9 by a blast medium flowing with high velocity in the axial direction. The blast medium charged with fibres then arrives in a subsonic diffuser 11 in order to reduce the flow velocity. The fibre-charged stream 10 is subsequently led onwards in a rectangular shaft 13. To separate non-fibrous constituents (so-called shots), a plurality of gas jets 18 are blown in at the shaft end transversely to the main flow direction at an angle .alpha. of 30.degree. to 120.degree.. As a result the fibre-charged stream is deviated. The stream 22 deviated in a direction of .beta.=60.degree. to 140.degree. is then picked up by a fibre shaft 21 mounted at the same angle .beta. and led to a deposition belt 23. The non-fibrous constituents (shots) 19, on the other hand, owing to their lower air resistance and higher inertia, fall through between the gas jets 18 and reach the lower discharge shaft 20.
