A fibre forming device for fabricating mineral fibres, includes a fibre forming spinner wheel pierced to enable centrifugal fabrication of the fibres, the fibre forming device including at least one annular burner producing an annular gas flow to stretch the fibres and an evacuation system for evacuating smoke created by the burner, the device further including a system adapted to vary the temperature of the spinner wheel, the temperature variation system being a device for circulation of air between the annular burner and the evacuation system to control the smoke evacuation flow.

Device for modifying the temperature of a fibre-forming plate

An automated method for detecting glass-ceramic materials in cullet, includes detecting the glass-ceramic material in cullet, during which fragments thought to be glass-ceramic material are identified in the cullet, obtaining a digital image resulting from the detecting of the glass-ceramic material, the image including at least one group of pixels corresponding to a fragment thought to be glass-ceramic material, colorimetrically processing the image, during which at least the group of pixels of the image corresponding to fragments thought to be glass-ceramic material is processed by a colorimetric image processing module according to an RGB model.

Method for detecting glass-ceramic materials

An automated system for detecting glass-ceramic materials among a cullet, includes at least one white light source and at least one monochromatic ultraviolet light source, each being oriented to emit in the same emission region. The system includes an image acquisition device configured to acquire an image of the emission region and an image processing device configured to process each of the images acquired by the image acquisition device, the image processing device including a colorimetric image processing module configured to ensure the detection of the glass-ceramic material among other types of glass.
