##### Reference no: EM13305578

A two stage crushing operation feeds 0.6 m diameter ore into a primary crusher at a rate of 25mt/hr. 80% of the ore feeds through an 0.2m screen into a secondary crusher. 65% of the ore from the secondary crusher comes out of a 50mm screen.

a. draw a basic flow diagram for this operation

b. calculate the re-circulating load in the primary crusher

c. calculate the re-circulating load in the secondary crusher.
