  • Page 21: Setting Up

    Installation Grinding bowls made of tempered steel may have recesses on the surface caused during production. They do not have an impact on grinding or the grinding results and usually disappear after the first grinding operation. These recesses on the surface, if present, are within the range of the permissible production tolerances.

  • Page 22: Ambient Conditions

    Installation 4.4 Ambient conditions WARNING! Mains voltage – The device may only be operated indoors. – The surrounding air must not contain any electri- cally conductive particles. – Maximum relative humidity 80% for temperatures up to 31 °C, linearly decreasing down to 50% rela- tive 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 prevent operational transient emissions. The possible leakage currents resulting from filtering measures can trigger a conventional residual current circuit breaker in the mains line.

  • Page 24: Settings In Setup Mode

    4.6.1 Setting the imbalance check CAUTION! The imbalance check can be disabled at your own risk. Fritsch assumes no liability for damage resulting from the deactivation of the imbalance check! NOTICE! The highest level of sensitivity is set for the imbalance check as the factory default.

  • Page 25: Setting Time Units

    Installation NOTICE! The display above the right "–" button (x) in the TIMER field is set to 9 by default. This indicates that the imbalance check has been preconfigured to the highest sensitivity level, preventing the device from shifting position and any resulting damage to the device.

    If POWER SUPPLY is flashing, the device is in setup mode. If POWER SUPPLY is not flashing, repeat the procedure. NOTICE! "P5" must always be displayed in the REPETI- TIONS field. The Fritsch company will give no guarantee for damage resulting from disabling of the imbalance switch. - 26 -...

  • Page 27: Initial Start-Up

    Initial start-up Initial start-up Perform initial start-up only after all work as described in Ä Chapter 4 „Installation“ on page 20 has been carried out. 5.1 Switching on The device must be connected to the power supply if this has not been done already.

  • Page 28: Using The Device

    Using the device Using the device DANGER! Before starting the machine, make sure that the grinding bowl has been tensioned correctly and that there are no loose parts inside the device. There is a risk of loose grinding bowls or parts being projected. Failure to observe this will render void the guarantee, and releases us from liability for any resulting damage to the device or personal injury.
  • Page 29 Using the device CAUTION! The grinding element is subject to normal wear when used. 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 centrifugal forces during grinding may cause the grinding balls to penetrate the bowl's wall and damage the mill.

  • Page 30: Size Of The Grinding Balls

    Using the device The grinding bowls and grinding balls made of zirconium oxide are resistant to acids - apart from hydrofluoric acid. Normally choose a grinding bowl and grinding balls that are made of the same material. Exception: Tungsten carbide balls (< 20 mm) may be temporarily (a few minutes) combined with grinding bowls made of hardened steel.

  • Page 31: Number Of Balls Per Grinding Bowl (Independent Of The Material Quantity)

    Using the device 6.1.2 Number of balls per grinding bowl (independent of the material quantity) A higher number of balls will reduce the grinding time and the grinding result will have a smaller particle size distribution.

  • Page 33: Filling The Grinding Bowl

    Using the device NOTICE! If the minimum filling quantity is fallen short of, increased wear due to abrasion is to be expected. This can cause irreparable damage to the mill components. NOTICE! The filled in volume can increase during the grinding. Check the volume after a brief grinding time.

  • Page 34: Speed

    This means that the overall working time may remain the same. The wear is increased in this case though. Fritsch recommends however to use the maximum speed and to plan for enough pauses so that the wear is minimised.

  • Page 35: Weight Of The Balls (Type Of Material)

    Using the device 6.4.5 Weight of the balls (type of material) A higher mass (specific weight) of the grinding balls accelerates grinding.

    Accessories Re-tighten the screws in the additional clamping system with a hex key. DANGER! The additional clamping system may be loosened due to the clamping of the Safe-Lock using the clamping lever. Check the screw connections of the additional clamping system and the Safe-Lock tensioning device for tight fit before starting grinding.

  • Page 50: Preparation For Gassing

    Accessories We carry out a worker water bath test on all gassing lids. The part to be tested is sealed, a pressure of 5.5 bar is applied and it is immersed in a water bath. If there is a leak, bubbles will develop. The air bubbles that develop within a specific interval are evaluated by the worker/tester.

  • Page 51: Gassing

    Accessories 7.2.2 Gassing Slowly open the inert gas supply. Press a thin object (e.g. hex key) onto the top of the ventilation attachment (e) so that the air can escape from the grinding bowl. The inert gas now purges the air from the grinding bowl. The duration of purging has to be determined through experimenta- tion.
