Using the device Grinding bowl min. filling max. filling 45 ml 3 ml 20 ml 12 ml 0,5 ml 5 ml Filling the grinding bowl CAUTION Do not fill in any dry ice of liquid nitrogen in the grinding bowls! Adding dry ice or liquid nitrogen into the grinding bowls can lead to a sudden increase in volume with a high static pressure. -
Page 30: 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 31: 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. (see table in ⮫ Chapter 6.1 ‘Choice of grinding bowls and grinding balls’ on page 25 ). 6.4.6 Dry grinding DANGER Dust explosion! -
Page 32: Clamping The Grinding Bowls
Using the device During the transition to grinding in suspension, you can add a liquid auxiliary 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. isopropanol) We recommend that you only use so much liquid that the suspension has the same consistency as motor oil. -
Page 33: Grinding Duration
Using the device NOTICE If the weights of the bowls differ too much, this may result in the planetary micro mill shifting position on the supporting surface. Grinding duration WARNING Burn hazard! Grinding bowls can get very hot after long grinding durations. Wear protective gloves for removal after grinding or during the grinding breaks. -
Page 34: Setting The Speed
Using the device To reduce the grinding time, you can use a grinding bowl and grinding balls with a higher density, and thus a higher impact energy. The mill can also run for several hours during low-speed operations for mixing and homogenisation. -
Page 35: Changing The Time Unit In Setup Mode
Using the device − If the combination minutes/seconds is set in setup mode instead of hours/minutes (see ⮫ Chapter 6.9.1 ‘Changing the time unit in setup mode’ on page 35), the numbers at h indicate the minutes and at min the seconds!
