Abstract: A device for the layer-wise additive production of a complex three-dimensional component has a measuring mechanism for continuously monitoring quality indicators during the production of the component, wherein the measuring mechanism and a bed with a material powder are surrounded, at least in regions, by a processing cell filled with a protective gas atmosphere and the material powder of an uppermost layer can be melted in a locally limited manner in a melting zone by means of at least one laser. The measuring mechanism has the at least one laser and at least one optical sensor for the priority detection of the quality indicators in the region of the melting zone, in particular by means of Raman spectroscopy. Consequently, any construction errors in the component can be recognised, evaluated and, if necessary, corrected in a resource-saving manner without delay.

Abstract: The present invention relates to a centrifugal machine (1) for drying granular solid materials, comprising a hopper (2), a centrifuging mechanism (3), associated to the hopper (2), provided with a rotary helical device (6) enabling the transport of the granular solid materials. Said centrifuging mechanism (3) is also provided with a perforated rotary piece (7), surrounding the rotary helical device (6) configured to remove, by centrifugal force, free liquids adhered to the surface of the granular solid materials. Additionally, the machine (1) comprises a solid outlet duct (5) and a solid collecting chamber (8), arranged between the centrifuging mechanism (3) and the solid outlet duct (5), capable of receiving the centrifuging granular solid materials from the rotary piece (7). The solid collecting chamber (8) is provided with a solid conducting rotor (9), which comprises radial blades (10) configured to push the granular solid materials and impart an increase in tangential velocity to them.
