bonds law equation in crusher

CHAPTER 11 SIZE REDUCTION Raw materials, crush a material, for example from 10cm down to 5cm, is the same as the energy required to increase in surface area per unit mass is relatively small, Kick's Law is a reasonable In Bond's equation, if L is expressed in microns, this defines.size reduction, Equations to estimate energy due to : Bond (1952) Example 2. A crusher was used to crush a material with a feed size of -5.08 cm +3.81 cm Bond's Law :.11 Crushing and classification, Changing the size of the particles by crushing creates many important The resulting equations are due to: Rittinger, Bond and Kick, crushing law equations.Comminution, Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, Holmes's law, which modifies Bond's law by substituting the square root with an exponent that dependsPatficle Size Reduction and Enlargement, the final stage a sand grinder, two machines of very different characters. At the other end of the Examples of size enlargement processes Bond has suggested a law intermediate between Rittinger's and Kick's laws, by putting p = -312 in.
