Question

Exercise 2: The size distribution of 35 kg crushed rocks has been analyzed using sieving method. The results of the sieving process are tabulated in the next table (standard mesh). The density of the particle is

1550k(g)/(m^(3))

and the shape factor are

a=0.8

and

\Phi =0.65

, Calculate: a) The specific area of particles (Aw)

(m(m^(2))/(g))

for the material between 4-mesh and pan. b) Number of particles in mixture ( Nw ) (particles

/g

) for the material between 4-mesh and pan c) What fraction of the total number of particles in the 150/200 mesh increment? d) If

95%

of the crushed glass must have size less than 1.25 mm , please state whether or not the particles need to be crushed again? e) What is the apperture diameter Dpi of up to about

80%

of \table[[Mesh,\table[[Mass fraction],[retained,
