The steel industry underpins the global economy. It intersects with other industries to a far greater degree than most commodities. Steel's deep entanglement with global markets exposes it to risks and opportunities from all directions – from protectionist and tariffs green tariffs to Covid-19 and supply chain disruptions.
The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).
The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work ...
