Mechanical Operations
Rittinger number which designates the new surface prduced per unit of mechanical energy absorbed by the material being crushed, depends on the
Ultimate strength of the material
Elastic constant of the material
State or manner of application of the crushing force
States that the work required for the crushing is proportional to the new surface created
Is less realistic in estimating the power requirements of commercial crushers
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
Calls for relatively less energy for the smaller product particles, than does the Rittinger law
