### MILLING & ANALYSIS OF PARTICLES

2.2 Milling kinetics The changing particle size distribution of the milled good as a function of time is most easy to characterize qualitatively if the material has initially only one particle size. At the start of milling the ﬁrst size class is continually diminished, (Curve A Fig. 3) ﬁrst faster and then slower.

Therefore the speciﬁc milling work may be described as follows: W M,R = C R 1 d p,ω − 1 d p,α, Where d p,α is the particle size of the initial milling goods, d p,ω is the particle size of the milled good and C R is a constant depending on the properties of the milling good and the mill and has to be determined experimentally. Rittinger

Dec 01, 2019· Fermions have a particle spin equal to a half-integer value (-1/2, 1/2, 3/2, etc.). These particles make up the matter that we observe in our universe. The two basic constituents of matter are quarks and leptons. Both of these subatomic particles are fermions, so all bosons are created from an even combination of these particles.
