    Installation Installation 3.1 Transport The device is delivered on a transport pallet with a wooden cover. We recommend using a forklift or pallet truck for transporting the packed device. DANGER! Do not step under the transport pallet during transport. WARNING! Improper lifting can lead to personal injury or property damage.

  • Page 21: Setting Up

    Please store the transport packaging in order that it can be reused in case you need to return the product. Fritsch GmbH denies all liability for any damage due to improper packaging (non-genuine packaging).

  • Page 22: Ambient Conditions

    Installation 3.4 Ambient conditions WARNING! Mains voltage! – The device may only be operated indoors. – The surrounding air may not carry any electrically con- ductive dust. – Maximum relative humidity 80% for temperatures up to 31°C, linearly decreasing down to 50% relative humidity at 40°C.
  • Page 23 Installation NOTICE! Fritsch mills are speed controlled. The devices are equipped for this with frequency converters. In order to comply with the EMC directive, many measures must be taken to pre- vent operational transient emissions. The possible leakage currents resulting from filtering meas- ures can trigger a conventional residual current circuit breaker in the mains line.

  • Page 29: Overpressure Relief Of The Grinding Bowls

    Using the device 5.1.2 Overpressure relief of the grinding bowls The grinding bowl seals have a sealing effect but are also for overpres- sure relief. If the pressure increases gradually during grinding, the special seals open at a certain pressure and release the overpressure in a defined manner.
  • Page 30 Using the device Be extremely careful if solvents are used. 60 ml isopropanol in an 80 ml grinding bowl results in the development of the following pressure and temperature: Temperature of grinding bowl Pressure in the grinding bowl wall [°C] [bar] 10.5 The overpressure limit for fluororubber flat seals is reached at 120 °C...

  • Page 31: Grinding Bowl Lid

    Using the device 5.1.3 Grinding bowl lid The grinding bowl lids seal the grinding bowl gastight after manual pre- tensioning (see also Ä ‘Safety measures against an excessively high pres‐ sure’ on page 40). The locking hooks are designed to withstand an internal grinding bowl pressure of up to 40 bar.
  • Page 32 Using the device CAUTION! The grinding element is subject to normal wear during use. Before every grinding operation, check the wall thickness of the grinding bowls. In the event of severe wear, replace the grinding bowl. If this is not done, the prevailing high centri- fugal forces during grinding may cause the grinding balls to penetrate the bowl's wall and damage the mill.

  • Page 36: Filling Quantities Of Grinding Bowls

    Using the device The large surface of many small balls results in high thermal stress due to the friction effect. It can already be measured after 5 minutes of grinding above 100 °C by a surface sensor on the surface of the lid. Inside the grinding bowl, the temperature is then much higher.

  • Page 37: Filling The Grinding Bowl

    Using the device 5.5 Filling the grinding bowl Do not fail to comply with the following sequence: Place the grinding balls in the empty bowl. Fill material to be ground over the balls. CAUTION! Never operate the device without material to be ground, otherwise the grinding balls and grinding bowl will be dam- aged.

  • Page 38: Number And Size Of The Balls

    Using the device 5.6.4 Number and size of the balls Pre-grind course, hard material with large balls: reduced percentage of fine material! Many small balls increase the percentage of fine material during extended running time. 5.6.5 Weight of the balls (type of material) A higher mass (specific weight) of the grinding balls accelerates grinding.

  • Page 39: The Effect Of High Temperature

    Using the device During the transition to grinding in suspension, you can add a liquid aux- iliary agent with high boiling point and low vapour pressure, e.g. water, white spirits (boiling point 100 - 140°C), or alcohols with a high boiling point (e.g.

  • Page 40: Safety Measures Against An Excessively High Pressure
