    Using the device Using the device WARNING! If the grinding elements used are not original accessories, we assume no guarantee and exclude all liability for damage to the device or for personal injury. WARNING! Make certain before starting the machine that the grinding elements have been properly installed and locked in place and that there are not any loose parts inside of the device.

  • Page 25: Rotors

    Using the device NOTICE! Risk of overheating! Due to the operating principle, the PULVERISETTE 14 pre- mium line heats up even when idling. The temperature is monitored by a safety device at the labyrinth disk and switches the device off when 80 °C has been reached. For continual comminution, plan regular breaks to allow the system to cool down and to clean it.

  • Page 26: Sieve Ring

    As a general rule, approx. 2/3 of the feeding amount is milled finer than 1/2 of the perforation diameter. Sieve rings with trapezoidal perforation, available as orig‐ inal accessories from Fritsch, can have manufacturing sieve opening tolerances of up to +/‐ 20% of the nominal mesh width.

  • Page 30: Grinding With External Cooling

    Using the device 6.6 Grinding with external cooling For certain source materials, using coolants before milling can be benefi- cial for comminution. For instance, soft organic materials or special plas- tics can be made brittle by briefly immersing them in liquid nitrogen or storing them in a freezer before grinding.

  • Page 31: Grinding With Heavy-Metal-Free Or Metal-Free Grinding Elements

    Using the device 6.7 Grinding with heavy-metal-free or metal-free grinding elements To eliminate the influence of even the smallest amounts of iron, it is nec- essary to install iron-free grinding elements. The following parts must be installed: 12-rib rotor made of pure titanium, a sieve ring made of pure titanium with a reinforced edge a collecting vessel coated with PTFE, a lid with titanium insert.

  • Page 32: Continuous Feeding Of Source Material

    Using the device 6.8 Continuous feeding of source material The volume of continually fed source material may not exceed the volume of the inserted collecting vessel. To feed larger quantities of a free-flowing source material, use the vibra- tory feeder "LABORETTE 24". Set the feeder on a stand next to the variable speed rotor mill so that the end of the channel is located above the funnel.
