Rock-crushing and pulverizing

The rock-crushing and pulverizing laboratory is the first step of the GTC sample preparation and analytical chain. This step consist of crushing, pulverizing, sieving , as well as Gemini shaking table hydrodynamic separation - of rock and sediment samples mainly for the ISTerre research teams and occasionally for external laboratories.

The laboratory is composed of :

  • Jaw crusher (Dragon Babitless)
  • Disk pulverizer (Fritsch)
  • Agate crusher ((Tema industrie/Siebtechnik) fine granulometry for geochemical and X-ray diffraction applications
  • Sieving columns (40 μm-2 mm grain size separation)
  • Gemini shaking table (separation of light and heavy minerals)
  • Laboratory oven for drying samples
Broyeur à mâchoires (Dragon Babitless)
Broyeur a disques (Fritch)
Broyeur à agate (Tema industrie/Siebtechnik) permettant à la préparation d’échantillons pour la géochimie ou les analyses au Rayon-X
Table hydraulique vibrante permettant de séparer les minéraux lourds d’échantillons broyés
