The use of the following FRITSCH mills are recommended:
a) Coarse Grinding or Cutting mill with 4 and 1 mm or similar stainless steel bottom sieve
Depending on the application, the Cutting Mill pulverisette 15, the Universal Cutting Mill pulverisette 19 or the Power Cutting Mill pulverisette 25 should be used.
b) Centrifugal mill with 250 µm tungsten carbide (WC) coated steel sieve, WC-coated rotor, (for uniform plastic material a 1mm steel sieve is appropriate). In order to avoid any risks of impurities during milling a 1 mm titan
The Variable-Speed Rotor Mill pulverisette 14 with standard rotor and sieve ring made of stainless steel or TiN-coated rotors and sieves should be used.
c) "Freezer" bladeless cryogenic impact grinder / mill with self-contained liquid nitrogen tub, insulated case, speed control, programmable timer, and safety interlock.
The Vibratory Micro Mill pulverisette 0 with Cryo-Box meets exactly these requirements.
Conclusion: The implementation of the above-mentioned EU directives will make the preparation of electrical and electronic scrap necessary in many laboratories. With the mills described above and the worldwide experience of FRITSCH in this field also your sample will be perfectly prepared for the following analysis.
