Please note: For the Planetary Micro Mill PULVERISETTE 7 premium line, you require at least 2 grinding bowls of your choice and the corresponding number of grinding balls. The grinding bowl material must also be harder than the material to be ground. In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used. Please take note of the useful capacity, this is not identical with the bowl volume!

  • Material data for grinding bowls / balls

    Material Main component of the material Density g/cm³ Abrasion resistance Used for grinding material
    Agate SiO2 2.65 good soft to medium-hard samples
    Sintered corundum Al2O3 (99.7%) 3.8 fairly good medium-hard, fibrous samples
    Silicon nitride Si3N4 3.25 excellent abrasive samples, metal-free grinding
    Zirconium oxide ZrO2 5.7 very good fibrous, abrasive samples
    Hardened, stainless steel Fe – Cr 7.7 good hard, medium-hard, brittle samples
    Hardmetal tungsten carbide WC 14.3 very good hard, abrasive samples

  • Additional Information

    Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the required mass per grinding bowl.

    The specified ball filling per bowl is the minimum quantity and should possibly be increased depending on the material properties. The useful capacity depends on the type of material. In exceptional cases, the number of grinding balls can be reduced by up to 15 %. However, increased abrasion should be expected. In general, smaller grinding balls achieve finer grinding results.

    In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.

Please select 2 grinding bowls, which are offered in the sizes 20 ml, 45 ml and 80 ml to perfectly match your sample volume. The useful capacity of the grinding bowls can be found in the selection aid. All grinding bowls of the FRITSCH premium line are cased in stainless steel, have a label and the same inner diameter regardless of their volume.
For the best grinding results in each individual case, all grinding bowls are available in 6 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion.

replacement seal ring Silicone 57.5 x 48 x 2 mm for all other <i>premium line</i> grinding bowls 80 ml, 45 ml, 20 ml volume

Replacement seal ring made of silicone 57.5 x 48 x 2 mm for all other premium line grinding bowls 80 ml, 45 ml, 20 ml volume.
With a fixed flat seal in the lid, the premium line grinding bowl is so tightly sealed that even grinding in suspension without an additional seal is absolutely smooth and problem-free.
When grinding in solvents or dry grinding of slightly caustic samples, we recommend our seal rings made of Viton (Article No. 84.0341.15) because they have a much higher chemical resistance.

  • Additional Information

    Grinding balls with diameter 3 mm and smaller must be weighed out. The above table provides you with the required mass per grinding bowl.

    The specified ball filling per bowl is the minimum quantity and should possibly be increased depending on the material properties. The useful capacity depends on the type of material. In exceptional cases, the number of grinding balls can be reduced by up to 15 %. However, increased abrasion should be expected. In general, smaller grinding balls achieve finer grinding results.

    In normal cases, grinding bowls and balls of the same material are used. To shorten the grinding time, grinding bowls and balls with a higher density and correspondingly higher impact energy can be used.

For achieving best grinding results grinding balls are available in 0.1 - 20 mm diameters and in 7 different materials, thus directly preventing contamination of the samples as a result of undesired abrasion. The recommended number of balls per grinding bowl can be found in the selection aid.

SPECIAL ACCESSORIES

The software MillControl enables the automatic control of the Planetary Micro Mill PULVERISETTE 7 premium line and validation of the grinding process. The actual rotational speed and power consumption are checked and documented. With the utilization of 2 EASY GTM grinding bowls with special lid and transmitter you turn your PULVERISETTE 7 premium line into an analytical measuring system for visualizing pressure and temperature during the grinding process.
For quickly and safely grinding in inert gas and for mechanical alloying premium line gassing lids are recommended.
A certificate for IQ/OQ documentation is also available.

SOFTWARE MILLCONTROL

Software MillControl for Windows
No. 83.5605.00
for Windows for automatic control of the mill and validation of the grinding process

The software MillControl enables the automatic control of the Planetary Micro Mill PULVERISETTE 7 and Planetary Mill PULVERISETTE 5 premium line and validation of the grinding process. The actual rotational speed and power consumption are checked and documented. The software is a distinct safety feature, since overpressure and a rise in temperature are avoided and defects on the mill and a sticking of the sample material prevented.

Detailed information on MillControl is available here


EASY GTM - GAS PRESSURE AND TEMPERATURE MEASURING SYSTEM FOR CONTROLLING THE GRINDING PROCESS

Receiver unit - board and software MillControl
No. 81.0013.00
receiver unit – board and software MillControl

Turn your Planetary Mill PULVERISETTE 5 premium line and Planetary Micro Mill PULVERISETTE 7 premium line into an analytical measuring system by using the EASY GTM system (Gas Pressure and Temperature Measurement System) with special lid and transmitter as well as a receiver board and the included MillControl software.
Your advantage: easy and safe monitoring and analysis of thermal effects, physical and chemical reactions or increases/decreases in pressure through continuous measurement of gas pressure and temperature directly in the grinding bowl. The mill is automatically controlled to ensure that the set parameters are not exceeded.
Especially practical: The receiver unit needs only to be inserted and adjusted just once – the software MillControl via USB only installed once - regardless of the number of EASY GTM-bowls used. 
Only one receiver unit with software MillControl has to be ordered. EASY GTM is also available for further grinding bowl volumes on request.
