37 5.13 Power failure during grinding If the power fails during grinding, grinding will be interrupted. All parameters are retained, and the remaining grinding time is saved. When the device is switched on again, a corresponding message appears in the display. You can continue the process by pressing the START button. The automatic saving of the remaining grinding time means the grinding then continues until the end of the originally set grinding time. For safety reasons the device must be opened and the grinding chamber inspected. Grinding then continues automatically when the lid is closed. The process is aborted by pressing the STOP button. . 5.14 Grinding Jar Selection for Different Sample Materials This device is only suitable for use with grinding jars from Retsch GmbH with a nominal volume of 12 ml - 500 ml. They are available in the following materials: • Agate • Sintered corundum • Zirconium oxide • Stainless steel • Special steel • Tungsten carbide 5.15 Sample quantity NOTICE If the fill level in the grinding jar is too high or too low, this will impair the milling result and may cause damage (increased abrasion) to the grinding set. 5.15.1 Guides for material quantity and balls for PM100 and PM100CM The PM100 and PM100CM are only suitable for grinding jars with a nominal volume of 12-500 ml. The PM200 is only suitable for grinding jars with a nominal volume of 12-125 ml. Grinding jar volume Sample volume Max. feed size Ball filling (unit)  5 mm  7 mm  10 mm  15 mm  20 mm  30 mm  40 mm 12 ml ≤ 5 ml < 1 mm 50 15 5 - - - - 25 ml ≤ 10 ml < 1 mm 100 25 8 - - - - 50 ml 5 – 20 ml < 3 mm 200 45 10 7 3 - - 80 ml 10 – 35 ml < 4 mm 250 70 25 10 5 - - 125 ml 15 – 50 ml < 4 mm 500 110 30 18 7 - - 250 ml 25 – 120 ml < 6 mm 1200 220 50 45 15 6 - 500 ml 75 – 220 ml < 10 mm 2000 440 100 70 25 8 4

38 In addition to the instrument settings, the filling level of the grinding jar is also of crucial importance for a successful grinding process in the Planetary Ball Mill of Retsch GmbH. When grinding bulk materials, the grinding jar filling should consist of approximately one third of sample and one third of ball quantity. The remaining third is the free grinding jar volume, which is required for the movement of the balls. If an increase or decrease in sample volume is to be expected during the grinding process, the amount of sample can be adjusted within the range listed in the table. Thus, e.g. for voluminous materials such as wool, leaves, grasses and similar, a material filling level of 70 – 80 % is necessary. For wet grinding with grinding balls < 3 mm, the ball charge should be 60 % of the grinding jar volume. 5.16 Ultrafine grinding High degrees of fineness can frequently only be achieved using wet grinding. Improved final fineness can be achieved in dry grinding by adding a few drops of stearin or acetic acid and by using grinding balls with a Ø<10mm and a fill level of 70-80% of the grinding jar volume. 5.17 Stacking the grinding jars 5.17.1 Stacking the 50ml grinding jars NOTICE It is not possible to stack 50ml grinding jars in the PM200. Fig. 24: Stacking 50ml grinding jars on the PM100 and PM100CM You can also stack two 50ml grinding jars on top of one another. You will need the optional adapter to stack the grinding jars. Stacking process: • Place the grinding jar (M1) in the grinding jar plate • Place the adapter (A1) on the lid of M1 • Place grinding jar (M2) on the adapter • Clamp the grinding jars as described in the chapter “Clamping the grinding jars”. M1 A1 M2

39 5.17.2 Stacking grinding jars smaller than 50ml Fig. 25: Grinding jars with a capacity of less than 50ml can be stacked on top of each other directly without the use of accessories. Stacking process: • Place the grinding jar (M2) directly on top of grinding jar (M1). • Clamp the grinding jars as described in the chapter “Clamping the grinding jars”. 5.18 Handling grinding jars CAUTION Scalding/burns Hot grinding jar – Depending on the grinding process, the material being ground and accordingly the grinding jar can become very hot. • Wear appropriate protection always when touching the grinding jar if it is hot. • Never open hot grinding jars! Allow the grinding jars to cool down to room temperature before opening. 5.18.1 Carrying and gripping Fig. 26: Grinding jar gripping flanges The gripping flanges (GR) on the grinding jar lid permit secure handling. M1 M2 GR GR

40 5.18.2 Anti-rotation device Fig. 27: Anti-rotation device All 250ml and 500ml grinding jars have a drilled hole (BV) underneath the grinding jar as anti- rotation device. The anti-rotation device is only used with the PM100 and PM 100CM and is located on the side of the grinding jar casing with lettering. 5.18.3 Heating the grinding jars Depending on the grinding time and the fill level, the grinding jars can be heated to a temperature of up to 150°C during grinding. This temperature change causes the pressure inside the grinding jar to increase. When unscrewing the lid, please note that this excess pressure is released by a sudden escape of air. This may be accompanied by particles of sample material. Fig. 28: Prising the grinding jar lid open VS BV HB

41 When grinding jars have been left to cool, a vacuum is created inside them which can make them difficult to open. The grinding jars can be prised open between the gripping flanges on the lid and the grinding jar, e.g. using a flat wooden stick (HB). 5.19 Grinding jar identification Fig. 29: Grinding jar lettering All grinding jars can be identified by a labelling field which shows the article number and material (SCH1). 5.19.1 Customer labelling on the grinding jar In addition to the labelling field specified above, you can stick one of the supplied labels or labels obtainable as accessories to the area on the grinding jar indicated (SCH2) to provide information about the grinding jar content for example. The label is heat resistant to 150°C and can be cleaned using alcohol or acetone to remove any lettering you have applied. 5.20 Grinding jar cleaning Fig. 30: Removing the O-ring The O-ring (OR) on the groove (NU) on the underneath of the lid can be lifted out easily to clean the grinding jar. Grinding jars, including those with glued ceramic inserts, can be cleaned using alcohol, benzine or normal household detergents. NOTICE When cleaning, do not expose grinding jars with ceramic inserts to sudden temperature differences. Sudden temperature fluctuations can cause the ceramic inserts to crack. NU OR

42 5.20.1 Drying the grinding jars After cleaning, the grinding jars can be dried in the drier cabinet at the temperatures specified below. Grinding jar material Temperature Special steel Up to 200°C Stainless steel Up to 200°C Tungsten carbide Up to 150°C Sintered corundum Up to 120°C Agate Up to 120°C Zirconium oxide Up to 120°C Silicon nitride Up to 120°C 5.21 Opening and Closing the Grinding Jar After filling the grinding jars, they should be closed using the locking mechanisms available as an accessory. Fig. 31: Locking mechanism In the case of grinding jars with material inserts made of ceramics or TC, only use locking mechanisms that support the material insert in the grinding jar lid. This is essential due to the expected internal pressure. NOTICE During wet grinding in grinding jars with material inserts, do not use the older locking mechanisms. Older locking mechanisms only clamp the gripping flanges of the grinding jars, which means that the material inserts may be pushed out if internal pressure arises. Use of agate grinding jars for wet grinding with solvents should in particular be reconsidered because of the internal pressure that arises and the inhomogeneous material properties of a natural product. Tighten the clamping screws on the locking mechanism to 2.5 Nm. Only with this initial tension are internal pressures of up to 5 bar permissible. NOTICE Damage to the grinding jar lid and the device The three screws on the safety clip of the aeration cover may become loose and damage the inside of the device. After tightening the safety clamping device, check that the three screws on the safety clip are still screwed tight.

43 Please note that the grinding jars may heat up to over 100°C depending on the grinding jar size, the ball filling, the speed and the grinding time. The PM100 is fitted with a fan which extracts the waste heat created during grinding directly from the grinding chamber. The extraction volume per hour is greater than 20 times the grinding chamber volume. The fan has standstill monitoring with signalling. The airflow from the fan during grinding can be discharged into an extractor hood if necessary. Check that the locking mechanism is secure before removing the grinding jar. Only remove grinding jars with locking mechanism, and only open after cooling when in a safe position (extraction device). 5.22 Wet Grinding with Highly Flammable Materials Wet grindings using highly flammable materials are permissible with this device when complying with specific precautionary measures. When using highly flammable materials as grinding aid, such as hexane, isopropanol, ethanol, petrol or similar, it is to be assumed that the inside of the grinding jars should be classified as zone 0, i.e. a constantly present explosive mix. Therefore, it is necessary to prevent potentially explosive vapours during the grinding process from escaping from the clamped grinding jars and from entering areas in which the requisite ignition energy is present. These vapours may be pressed out of the grinding jar in particular by the heating which takes place and the resulting pressure increase inside the grinding jar. It is therefore urgently recommended that the managing operator (employer) using the device assesses the dangers that exist before using corresponding solvents, taking local conditions into account, as part of a coherent explosion protection concept. If necessary, supplementary organisational measures should be recorded in writing in an explosion protection document. This procedure is regulated in the EU under Articles 118 and 118a of Directive 89/391/EEC. In other countries outside the EU, the comparable provisions are to be observed. The following must be verified with respect to the device: − Only grinding jars with safety closure devices may be used! − It is necessary to consider the durability of the O-rings (EPDM 75° shore) when selecting the solvent and the durability of the adhesive used when using ceramic inserts. − The safety closure devices of the grinding jars must be tightened firmly. − Please note that the grinding jars can heat up considerably depending on the grinding jar size, the ball filling, the speed and the grinding duration. − Before removing the grinding jars, the tightness of the safety closure devices must be check anew.

The basic prerequisite both for the safety of the operator and for the life of the machine components is careful clamping of the grinding jars. Please remember that this device involves grinding equipment which applies very high amounts of energy into the sample material, and that the grinding set therefore needs to be locked into position carefully. Correct securing of the grinding jar is always queried prior to starting the machine in order to prevent operating errors. Employees who have been especially trained and who are familiar with operation of the PM can also permanently fade out this safety notice. We do not recommend this course of action, particularly when there are changes in operating staff! The device software is set up such that the displayed message about clamping the grinding jars must be confirmed whenever the start button is actuated prior to starting the machine. The grinding process begins after confirmation. This safety notice can be faded out in the “Settings” menu.
