Comparative study of SPEX and planetary milling methods for the
that the higher milling speed in the SPEX milling method leads to a higher milling energy and consequently lower particle size. For the same milling time of 2 h, the particle size decreases down to nano-scale using a SPEX ball mill whereas the planetary ball mill products contained a varied size in the range of micron and submicron regimes.In this study, we investigate the effect of the ball size in a high-energy ball mill on the comminution rate and particle size reduction.

Silicon Powder Properties Produced in a Planetary Ball Mill as a
Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead Planetary Ball Mills (Figure 5 a) In this picture, the bulk consolidated sample corresponding to these powders displayed a wide particle size dispersion (50 to 280 nm in diameter).

Graphite Particle Reduction Process using High Energy Milling
The particle size of graphite has decreased in PBR 2:1 and 3:1, but in PBR 4:1 there are particles of increasing size. Particle size changes are caused by collisions between graphite particles and the ball mill used and friction force [1]. The milling process is described as a kinetic process whereNote D50 = 250 nm does not mean the average particle size is 250 nm but rather that 50% of the particles fall below 250 nm size. Based on these two parameters, samples ball milled samples ball-milled at 500 and 1000 rpm for 15 and 30 min; and at 1500 rpm for 5 min are desired.Insight into ball milling for size reduction and nanoparticles
