Page 8: Safety Information And Use
Subject to technical modifications. 2.2 Scope of application The PULVERISETTE 6 classic line can be applied universally for the fast, dry or wet grinding of inorganic and organic samples for analysis, quality inspection, material testing or mechanical alloying. During the synthesis, the PULVERISETTE 6 is used for mixing and homogenising dry samples, emulsions or suspensions. -
Page 9: Operating Principle
Safety information and use 2.2.1 Operating principle The grinding stock is crushed and ground by grinding balls in a grinding bowl. The centrifugal forces resulting from the rotation of the grinding bowls around their own axes and from the rotating support disc (14) influence the contents of the grinding bowl consisting of grinding stock and grinding balls. -

Installation The room temperature should be between 5 and 40 °C. Altitudes up to 2000 m Degree of pollution 2 according to IEC 60664-1:2007. 4.5 Electrical connection DANGER! Provide short-circuit protection! Risk of damage due to short-circuits. – Make sure that the socket is connected to a mains line protected with a residual current circuit breaker. -
Page 23: Adjusting The Mains Voltage
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 26: 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 27: 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 28 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 29: Size Of The Grinding Balls
Using the device 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. 6.1.1 Size of the grinding balls Type of feed material Suitable ball diameter Hard samples with a maximum feed size of 10 mm... -
Page 30: Recommended Number Of Balls Per Grinding Bowl (Independent Of The Material Quantity)
Using the device 6.1.2 Recommended 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 32: 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 33: Factors With An Impact On Grinding
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 34: Number And Size Of The Balls
Using the device 6.4.4 Number and size of the balls NOTICE! It is not recommended to mix balls with different diam- eters and/or materials (bowls and balls must always be of identical material!). If balls with different diameters are used, increased wear and damage to the grinding elements is to be expected. -
Page 35: Wet Grinding (Grinding In A Suspension)
Using the device At a particle size of less than 20 µm, the surface forces prevail. The grinding stock begins 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 %) Stearic acid 2-3 % Aerosil (fine-particle silicic acid) 0.5 - 2 % Quartz sand ~ 2 %... -

Using the device 6.6 Mass balance Click on the following link to watch a step-by-step video guide on how to adjust the counterweight. Click here. The counterweight (6) has to be positioned according to the scale in order to offset the imbalance and thus prevent the mill from shifting. The weight indicated on the scale is the weight of the filled grinding bowl with the lid on. -
Page 40: Settings On The Control Panel
Using the device To what extent the heating up of the material to be ground needs to be observed naturally depends on the corresponding sample in each individual case. Note à a longer duration may also require a long pause time for cooling down. - Page 41 Using the device Setting the grinding time Press the "MILLING" button. ð The "MILLING" button lights up Press the + or - buttons to set the running time in hours (0–99) and minutes (0–59) or in minutes (0–59 and seconds (0–59).

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. -
