You are given the following experimental data from a particle size analysis performed on two

specific samples, namely secondary crusher product and the ball mill product. For each

dataset do the following:

Secondary Crusher Product:

Ball Mill Product:

a$)$ Calculate the cumulative size distribution at given particle sizes.

b$)$ Determine which of the standard empirical distribution functions fits the data the best.

c$)$ Determine the main fitting parameters $($size and distribution modulus$)$ for the function

that you judge to be the best.

d$)$ What is the fraction passing $40$ mesh and $60$ mesh?

e$)$ What is the fraction held between $1$ and $0\mathrm{.}5$ mm $?$

f$)$ Determine $d_{80},d_{50}$ and $d_{10}$ particle sizes.
