Bond Impact Crushing Work Index -Procedure and

2021-1-14  Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed. A crude test ...

Bond Work Index - an overview ScienceDirect Topics

The Hardgrove index is determined using the ASTM method D 409–71. It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured ( w grams) and the index is defined as I = 13 + 6.93 w.

A new method for coal and gas outburst prediction

Based on the new surface theory , the work consumed during the process of coal crushing is proportional to the new surface added after crushing. Therefore, the work required to crush a unit volume of coal can be expressed as (3) w = K R 1 D ¯ - 1 d ¯ where w represents the crushing work ratio, kJ/m 3 ; and k is a constant that depends on the nature of the coal sample and its breaking mechanism.
