Question

Calculate the energy required to crush 100 tonnes per hour of limestone if 80% of the

feed passes through a screen 4.00 cm aperture and 80% of the product passes through

a screen with 0.04 cm aperture. The work index for the limestone is 12.70, when the

capacity is expressed in tonnes per minute, energy required is in horsepower (HP) and

size of the feed and product in feet.​

Answer 1

Answer:



Explanation:

Don't know sorry

Answer 2

Answer:

Dsa=3.75cm

Dsb=0.03cm

m=100t/h

Wr=12.7

p/m=0.3162Wr[(1/√Dsb)_(1/√Dsa)]

p=669696W=8.9Hp
