  • Page 24: Using The Device

    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: Impact Element

    Using the device NOTICE Risk of melting! Feed material with unknown properties or material with a low melting point to the device in small quantities. After test grinding, check the grinding elements for melting. If this is the case, the comminution material must be "embrittled" before grinding with the PULVERISETTE 14.

  • Page 26: Sieve Ring

    Grinding tools are not covered by the warranty terms of FRITSCH GmbH! 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 27 Using the device Carefully set the labyrinth disk (7) over the motor mounting flange (8) until it lies flush on the motor mounting flange (8). For this, pay attention to the temperature sensor – it must fit into the bore hole on the underside of the labyrinth disk.

  • Page 28: Cutting Insert

    Using the device Cutting insert 6.2.1 Cutting rotor The cutting rotor with cooling fins is equipped with 3 rotor blades. These are available as hardened, stainless steel (14.6590.00) and as tungsten carbide (14.6595.00). For use in heavy metal and iron-free grinding, the cutting rotor is available with rotor blades and fixed knifes also made of titanium (14.4690.00) and zirconium oxide (14.6595.00).

  • Page 29: Inserting The Cutting Insert

    Using the device The fixed knives can be removed using a Torx 20 key. When unscrewing the fixed knives, be aware that they are under spring pressure and can shoot out when loos- ening the screws. When reinstalling the knives, always observe the direc- tion of rotation of the rotor.
  • Page 30 Using the device We recommend the use of a high-performance cyclone in combination with an extraction system. This provides a better and quicker throughput and cools the system. To use the PULVERISETTE 14 premium line as a cutting mill, the accessories must be installed as follows: Position the special labyrinth disk in the grinding chamber.

  • Page 35: External Cooling

    Using the device 6.5.1 External cooling It is possible to exchange the lower ventilation grate on the rear panel against a cover plate (order no. 14.4214.00) with a connector for a vacuum cleaner (order no. 43.9070.00). This will provide faster airflow, thus cooling the system! Grinding with heavy-metal-free or metal-free grinding elements To eliminate the influence of even the smallest amounts of iron, it is necessary to install iron-free grinding elements.

  • Page 36: Continuous Feeding Of Source Material
