Using the device 6 Using the device CAUTION! Before starting the machine, make sure that the grinding set has been clamped correctly and that there are no loose parts inside the device. Failure to observe this will render void the guarantee, and releases us from liability for any resulting damage to the device as well as for any resulting personal injury.
Using the device 6.1 Preparing for grinding Preselect the speed, grinding duration and possible pause times and repeats. A grinding duration of 2 ‐ 4 minutes is sufficient in most cases to achieve a satisfactory grinding result. A longer grinding duration often does not result in a grinding progress for a smaller final fineness. When dry grinding for a longer period, the grinding stock cements to the grinding bodies and they are then rather difficult to clean. 6.1.1 6.1.
Using the device 6.1.3 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. Examples (maximum amount to be added in mass%) n n n n 6.1.4 Stearic acid 2-3% Aerosil (fine-particle silicic acid) 0.
Using the device CAUTION! Burn hazard! The grinding bowl can become hot during long grinding periods. Allow for cooling time after grinding. Wear safety gloves! 6.1.5 Filling the grinding set Filling quantity maximum as specified useable volumes (50, 100 or 250 ml). Filling quantity minimum 30 % of specified useable volumes. 6.1.6 1. Place all grinding bodies with the rounded edge downwards in the empty grinding cup. 2. Fill grinding stock into the grinding cup between the grinding bodies. 3.
Using the device 3. Grip the clamp lever directly over the turning point and turn forward. 4. Grip the clamp lever at the front handle and push all the way to the back. The eccentric is moved over its lowest point and clamps the grinding set tight. 5. A small lever on the right side of the clamp lever presses a safety switch that releases the device only when the clamping device (3) is actuated. In case the clamping device gets loose during the milling, the device shuts down immediately.
Using the device 10. Grip the clamp directly over the turning point then and turn it all the way back. 11. The grinding set is pressed upward out of the gap by the ball pressure pieces and can be pulled forward towards the body by the grips. 12. It can happen that the grinding set sticks to the rubber plate and cannot be moved forward because of that. A thin, firm object (such as a knife) can be slid between the rubber plate and the grinding set to loosen the rubber plate.
