Oct 15, 2015· The samples used in this work are either routinely cofired in coal fired power plants or have been used in biomass cofiring trials, as illustrated in Fig. wood pellets (mainly pine with a small amount of eucalyptus), Spanish olive cake (a residual waste mix from olive oil production formed of powdered olive pulp (0–850 μm), olive pips (850–3350 μm) and olive pellets/self ...
grindability is Bond''s work index which is defined as the resistance of the material to grinding. The standard equation used by them for the ball mill work index (Bond work index) is as follows. 230. 82 1 10 / 80 > 10 / 80 1. P G P F W i bg i u (4) In designing and optimizing a milling circuit using Bond
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.
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, and ...

This measures the resistance of materials to breakage. The Bond standard grindability test has been described in detail by Deister (1987) and Levin (1989) who proposed method to determine the grindability of fine materials (Wills, 2006). Abdullahi (1997) examined the work index of Ashaka limestone in Gombe state using the modified Bond''s method.
