Planetary Ball Mills for fine grinding of soft hard to brittle or fibrous materials.
The 911MPEPB500 Planetary Ball Mills are used for fine grinding of soft hard to brittle or fibrous materials Dry and wet grindings are possible They support the daily sample preparation for laboratory and development usage.
Planetary Ball Mills consist of several cylindrical grinding jars positioned on the sun wheel as shown on the figure which are filled with loose grinding balls Two superimposed rotational movements move the grinding jars.
Like in a planetary system the grinding jar rotates on a orbit around the centre This rotational movement is the self rotation of the grinding container superimposed The resulting centrifugal and acting acceleration forces lead to strong grinding effects Furthermore there are forces working according to the coriolis acceleration The result is an intensive grinding effect between the grinding balls and the sample.
There are different rotational ratios With a rotation ratio of 1 2 the grinding jar rotates twice during a sun wheel turn The minus of this case indicate the opposite rotation direction.
Depending on the speed ratio different movement patters of the grinding balls media can be achieved It can be achieved that the grinding media are crossing the grinding jar and loosen from the wall At hitting the wall of the grinding jar the sample will be stressed At a different motion pattern the grinding balls roll over the sample and stress the ground material.
Planetary Ball Mills enable the convenient programming of the following grinding parameters.
The selection of the right grinding jar and the correct filling level has a big impact on the grinding result According to the application you have to select the correct material and amountvolume for the grinding jar and the grinding balls.
A jar filling should consist of about 13 sample and 13 ball charge The remaining third is the free jar volume that is necessary for the movement of the balls The following table provides recommendations.
