P6 Planetary Ball Mill

The P6 is a high-speed planetary ball mill suitable for particle size reduction and homogenising powder samples, particularly for XRF measurement. It can quickly and efficiently reduce powders to tens of microns in size.

Grinding Media

As grinding media we recommend either zirconia or for harder materials tungsten carbide if you are not sure, this will suit the majority of applications. The maximum feed size is 10mm in diameter.  
Material (bowl+balls) Main components of the material Density (g/cm3) Abrasion resistance Sample type
Agate (99.9% SiO2) 2.65 Good Soft samples
Zirconium oxide (96.2% ZrO2) 5.7 Very good Fibrous, abrasive samples
Tungsten carbide (93% WC+6% Co) 14.9 Very good Hard, abrasive samples
Silicon nitride (90% Si3N4) 3.25 Extremely good metal-free grinding
Hardened steel Bowl: (11-12% Cr) Balls: (1.0-1.65% Cr) 7.9 Good Hard, brittle samples

Sample Volume

A typical mill to reduce the size of the solid and to produce a homogenous powder, which can be used in the pellet press, is a Planetary ball mill. The P6 is able to work with one 250ml bowl for 100ml of sample or with two 80ml bowls with 30ml of sample.

Number of grinding balls per bowl

Ball diameter (mm) Number of balls (80 ml bowl) Number of balls (250 ml bowl)
5 250 - 300 1200 - 1300
10 25 - 30 50 - 150
15 10 45 - 50
20 5 15 - 20
30 - 5-6
 

Results

The specification for the particle size is typically < 45 µm. After 10 minutes of grinding cement clinker in a 250 ml bowl the following particle size distribution is obtained: graph of particle size after milling powder The result is that 99.4% of the sample is reduced to under 45 µm after ten minutes. The two peaks correspond to material found at the center (larger particles) and edges (smaller particles) of the bowl.
