Copper ore is crushed in a gyratory crusher. The feed is nearly uniform $50\mathrm{.}8mm$ spheres. The differential screen analysis of the product is given in row $1$ of the table. The power required to crush this ore is $400kW.$ Of this, $10kW$ is needed to operate the empty mill. By reducing the clearance between the crushing head and the cone, the differential screen analysis of the product becomes that given in row $2$ of the table.

Using Bond's method, estimate the power necessary per ton of rock in each of the operations for a feed rate of $110$ tons $\frac{?}{h}.$
