100 ton/h of a rock feed, of which 80% passed through a mesh size of 2.54 mm, were reduced in size such that 80% of the crushed product passed through a mesh size of 1.27 mm. The power consumption was 100 kW. If 100 ton/h of the same material is similarly crushed from a mesh size of 5.08 mm to a mesh size of 2.54 mm, the power consumption (in kW, to the nearest integer) using Bond’s law, is

    's law is:

    First, we need to calculate the work index (Wi) of the material. Using Bond's law:

    Wi = (10/√1.27 - 10/√2.54) / (1/√1.27 - 1/√2.54)
    = 23.7 kWh/ton

    Next, we can use Bond's law again to calculate the power consumption for the second scenario:

    Wi = (10/√2.54 - 10/√5.08) / (1/√2.54 - 1/√5.08)
    = 12.3 kWh/ton

    Power consumption = (100/3600) * 12.3 * 1000
    = 342 kW (rounded to the nearest integer)

    Therefore, the power consumption for crushing 100 ton/h from 5.08 mm to 2.54 mm is approximately 342 kW.
