Place the lid on the grinding bowl. 6.4 Factors with an impact on grinding 6.4.
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 Ä Chapter 6.1 ‘Choice of grinding bowls and grinding balls’ on page 29). 6.4.6 Dry grinding Below a particle size of approx. 20 µm, the surface forces prevail and the material to be ground starts to "stick". Additional dry comminution can be achieved by adding surface-active substances to the material to be ground.
Using the device 6.5 Clamping the grinding bowls 6.5.1 Clamping with the "Safe-Lock" (5) tensioning device Fritsch GmbH confirms that every Safe‐Lock clamping system has been manufactured and tested to our internal quality standards. Fritsch GmbH measures the clamping force of each individual Safe‐Lock clamping system. The clamping force must be in the range of 11.2 ‐ 11.3 kN +/‐ 0.2kN. Carry out the following checks for every grinding before clamping the grinding bowls: n Has the rubber disc (6.
Using the device 3. Hang the short projection of the Safe-Lock tensioning device into the other side. 4. Push the Safe-Lock tensioning device so that the cut-out of the grinding bowl holder sits centrally in the U-shaped cut-out of the longer projection. 5. Pre-tension the setting screw (e) manually, then place the provided torque spanner on the setting screw (e) and turn until it clicks. 6. Then press the clamping lever downwards.
Using the device 6.5.2 Clamping the 80 ml grinding bowls There are two ways of clamping an 80 ml grinding bowl: 1. Place the reducer (o) (order no. 90.1120.09) into the grinding bowl holder and position the 80ml grinding bowl on it and fasten with the Safe-Lock tensioning device. 2. Alternatively, clamp two 80 ml grinding bowls on top of one another. Tensioning with the Safe‐Lock system proceeds as described in Ä Chapter 6.5.1 ‘Clamping with the "Safe‐Lock" (5) ten‐ sioning device’ on page 35. 6.
Using the device Depending on the application, the grinding duration should be adapted to the development of heat in the bowls. The temperature inside the bowls is 20 - 30 °C warmer than the outer casing temperature. CAUTION! The maximum temperature of the grinding bowl outer casing is 100 - 110 °C (agate, max. 70 - 80 °C). The grinding duration is therefore based on the maximum bowl temperature. The grinding duration at which the temperature is not exceeded depends on the material, ball, and speed.

Accessories 7 Accessories 7.1 Additional clamping system for grinding harmful substances or in a gas atmosphere. The additional clamping system is used to transport a grinding bowl filled with inert gas or harmful substances from a glove box to the planetary mill and back again. This ensures that no harmful substances can be inhaled. There are two ways of gassing the grinding bowls: 7.1.1 1.
Accessories 2. Position the pressure plate (b) with the rubber disc on the bowl as shown in the picture. 3. When using grinding bowls with a volume of 80 ml, the adapter piece (c) (90.1120.09) has to be used as well. NOTICE! Under no circumstances may 80 ml bowls be clamped on top of one another. This can lead to damage to the bowl and its component seals. 4. Then tighten both socket-head screws (d) shown in the diagram equally with a hex key and thereby clamp the pressure plate tightly.
Accessories 6. The pressure piece has to be removed in order to use the SafeLock system for tensioning. 7. Position the bracket (d) vertically! 8. Hang the longer projection of the Safe-Lock tensioning device onto one side of the mounting of the grinding bowl holder. 9. Hang the short projection of the Safe-Lock tensioning device onto the other side.
