During crushing, energy is used by the processes of: elastic deformation (not including breakage) of the particles, inelastic deformation, elastic deformation of equipment, friction between particles, friction between particles and machinery, noise, heat and vibration, and friction losses in equipment drives.

Shear crushing is accomplished by breaking along or across lines of cleavage. It is possible, when required, for a crusher to use a combination of two or three of these principles. The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering.

Procedure Option 1 (Soda/Pop Can) Place the water in the can. Place the can on the hot plate. Heat the water in the can until it fills with water vapor. Use the tongs, remove the can from heat and invert it, placing the opening in a shallow container of water. The can will collapse immediately. Footnotes References: 1. L.

terms. The index is defined as the energy required to crush from infinite size down to 100 µm, hence the 10 inside the brackets. Bond's Work Index values, in kWh per short ton: i.e. 2000 lbs or 907 kg, roughly follow the Moh's scale of hardness, see Table 11.1. In Summary, Kick's law is better for larger particles and Rittinger's

Where: E=Energy, K K =Kick's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Bond's Law states that the total work input represented by a given weight of crushed product is inversely proportional to the square root of the diameter of the product particles. Bond's Law can be written as:
