MoreComminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

MoreThe test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.

MoreThe 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, and

MoreBonds law is often written in terms of the work index (Wi) as, Where the work index is defined as the energy required per unit mass in kWh/ton to reduce an infinitely large particles to D80 = 100 μm. In the above equation, unit of D80 is in mm, of ‘W’ is kWh and of ‘m’ is in ton. Work index for common materials is Material Wi (kWh/ton)
