CPE: Lesson 13. Principle of Size Reduction

Crushing: when an external force applied on a material excess of its strength, the material fails because of its rupture in many direction. The particles produced after crushing are irregular in shape and size. The type of material and method of force application affects the characteristics of new surfaces and particles.

Bond Work Index

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, …

Based on Bonds Crushing Law the power required to crush …

See Page 1. • Based on Bond''s Crushing Law, the power required to crush a certain material will change by % if the diameter of the product is made smaller by 50%. • In crushing a certain ore, the feed is such 80% is less than 50.8 mm in size and the product size is such that 80% is less than 6.35 mm. The power required is 89.5 kW.
