Mechanical Operations
Bond crushing law

States that the work required to form particle of any size from very large feed is proportional to the square root of the volume to surface ratio of the product

Is less realistic in estimating the power requirements of commercial crushers

Calls for relatively less energy for the smaller product particles, than does the Rittinger law

States that the work required for the crushing is proportional to the new surface created
