Micro-broyeur à vibrations
PULVERISETTE 0
Veuillez tenir compte des points suivants : Le broyeur à billes à vibrations FRITSCH PULVERISETTE 0 doit être complété d'un mortier équipé d'une bille de broyage. Le matériau du mortier doit toujours être plus dur que le matériau à broyer. En règle générale, le mortier et les billes de broyage utilisés sont fabriqués dans le même matériau. Tous les mortiers FRITSCH – quel que soit le matériau – sont sertis dans un socle en aluminium résistant aux chocs, qui protège le mortier.
La Kryo-Box FRITSCH est destinée à fragiliser des matériaux mous, légèrement gras ou humides afin des soumettre à un broyage cryogénique.
Pour que le broyage et le tamisage soient regroupés en un seul instrument, combinez le broyeur PULVERISETTE 0 avec la
tamiseuse à vibrations ANALYSETTE 3 SPARTAN

ACCESSOIRES SPÉCIAUX
La Kryo-Box FRITSCH est destinée à fragiliser des matériaux mous, légèrement gras ou humides afin des soumettre à un broyage cryogénique. Il suffit de mettre en place la garniture de broyage remplie puis d'ajouter de l'azote liquide – mêmes les échantillons les plus difficiles à broyer se fragmentent facilement à la finesse requise pour l'analyse. La bonne isolation assure une consommation de réfrigérant particulièrement faible.
Des couvercles de tamisage spécifiques sont également disponibles pour un tamisage à sec et par voir humide.
Nous recommandons d'utiliser une cloche d'insonorisation pour réduire les bruits émis par le broyage.
ACCESSOIRES POUR BROYAGE CRYOGÉNIQUE
Device for grinding in liquid nitrogen.
The grinding set is placed in a cryo-box to grind soft, oily, fatty or moist materials by adding liquid nitrogen to embrittle the grinding material. This method is used to reduce samples which are very difficult to grind (e. g. slivers of soft PVC) to analytical fineness. The thick insulation of the cryo-box keeps coolant costs low.
For cryogenic grinding, a mortar and a grinding ball made of stainless steel, tempered steel or hard metal tungsten carbide should be used.
Please note: Grinding sets made of agate and sintered corundum cannot be used in the cryo-box.
Cloche d'insonorisation
To reduce the grinding sound, we recommend the sound absorption hood made of plexiglas.
COUVERCLE DE TAMISAGE
For dry sieving with test sieves 200 mm/8" dia.
The clamping lid made of plexiglas allows the operator to observe the sieving process.
For applications, where it is not required to observe the sieving process, a clamping lid without window insert article no. 31.2050.00, is also available.
This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN. The needed sieve pan and the sieves must be ordered separately.
For dry sieving for all test sieves up to 200 mm/8" dia.
The POM plastic clamping lid without window for applications, where it is not required to observe the sieving process, respectively in order to sieve materials where a metallic contamination must be avoided. For applications, where it is required to observe the sieving process, a clamping lid with window insert article no. 31.2020.00, is also available.
This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN.
The needed sieve pan and the sieves must be ordered separately.

With 2 rotation nozzles for wet sieving with test sieves 200 mm/8" dia.
The wet clamping lid features 2 rotation nozzles which sprays the entire interior chamber, thus helping to flush the material through the sieve apertures.
Especially recommended for materials with a high electrostatic charge or very high content of fine material. This clamping lid can also be used if you would like to use the Vibratory Micro Mill PULVERISETTE 0 as a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN. The needed sieve pan and the sieves must be ordered separately.
