Accessories for use as Cutting Mill

Selection aid
 
  • Sieve shells

    Fast comminution of medium hard to soft materials Sieve shells with trapezoidal perforation
    for additional shearing effects
    Fast comminution of brittle materials for achieving medium finenesses Sieve shells with square perforation
    for a larger throughput and less sample residue due to the larger, open sieve surface

    Sieve shell with round perforation
    for narrow grain size range

For standard applications of pre- and fine comminution of fibrous materials and plastics select the cutting rotor made of stainless steel.
The cutting rotor made of hardmetal tungsten carbide comminutes hard-tough materials. Choose in both cases additionally sieve shells with trapezoidal, square or round perforation made of stainless steel 316L.
For heavy-metal- and iron-free grinding and sample preparation according to RoHS use the cutting rotor with cooling fins and sieve shells holder made of stainless steel TiN-coated.
For comminution of soft materials choose rotor edges and fixed knives made of pure titanium and for hard-tough materials we recommend rotor edges and fixed knives made of zirconium oxide. Choose in both cases additionally sieve shells with trapezoidal perforation made of stainless steel TiN-coated.

SAMPLE EXHAUSTION WITH CYCLONE SEPARATORS AND FOR GRINDING LARGE QUANTITIES

FRITSCH Cyclone separators ensure with their powerful airflow simple feeding and faster throughput. The powerful airflow enables the use of finer sieve rings to achieve a higher final fineness. The cyclones are ideal for even for temperature-sensitive samples and materials which are otherwise difficult to grind finely, such as electrostatically-charged plastics or powder coatings. Two models are available: High performance Cyclone separator and small volume Cyclone separator.

High-performance Cyclone separator made of stainless steel 304 for sample exhaustion, incl. sample glass 1000 ml and connections for exhaust system.
The compact FRITSCH high-performance Cyclone separator, which is made completely out of stainless steel 304, is particularly indispensable in the analytical sector and the food and pharmaceutical industries. Due to its high surface quality, it offers enhanced resistance to corrosive media such as alkalis and acids, but particularly to media containing chlorides – and is especially easy to clean with a wide range of possible cleaning agents, without leaving any residues. The Cyclone separator can also be fully dismantled, meaning that it can be completely emptied, flooded and sterilised. Your advantage: reliable protection against cross-contamination.
