You can deploy the CryoMill for grinding with cooling or grinding without cooling.
5.6.1 Grinding without cooling
• Switch the CryoMill on at the main switch.
• Set the cryo cycles to - .
• Set the desired grinding time (B9)+(B11).
• Press the START button.
The START LED lights up. The remaining grinding time and the set frequency are
displayed.
5.6.2 Grinding with cooling
The following program points can be set when grinding with cooling.
– precooling (Vkz)
– grinding time (Mz)
– intermediate cooling time (Zkz)
– cryo cycles (Number of cooling/grinding cycles)
– frequency 1/s (Grinding frequency)
A single grinding cycle consists of the precooling and the set grinding time. The
intermediate cooling time does not apply in the case of a single grinding cycle.
