A crusher is fed with limestone having particles of 2 cm median equivalent diameter and discharges a product consisting of particles of 0.5 cm median equivalent diameter. The equipment operates at a capacity of 1.2 10⁴ kg/h consuming a power of 10 hp. If the requirements of the process demand a finer size of the product (0.4 cm of median equivalent diameter) decreasing the capacity to 1.0 10⁴ kg/h, determine the theoretical power consumption under the new conditions using Rittingerss law, Kicks law and Bond crushing law.
