Get priceThe 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). ...

No general work index formula governing energy use over a range of conditions, like the Bond equation for intermediate grinding, has yet been found for the fine grinding regime. Instead, the work-to-P80 curve is determined in the laboratory for each case. The energy use usually fits an equation of the form W = Aleft ( { {text {P}}80} right)^ {k}

Preparation. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln.This is accomplished by heating the material to above 825 °C (1,517 °F), a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO 2), leaving quicklime.

Therefore when the WI is increased the work required to maintain the same grind size increases. There are two options to accomodate this increase in work. The power of the mill can be increased and the production rate kept the same. Or the Power can be kept the same and the throughput should be decreased in order to maintain the grind size.

Bond defined the work index (W i) as the work (kWh per short ton) to reduce particle from theoretically infinite size to 80% passing 100 m. The Bond's formula is derived from an empirical law of comminution with the exponent of 1.5 as followed: E B = 10W i (1/X p,80 0.5 - 1/X f,80 0.5) (1) where E B is the specific energy (kW/STPH), X p,80 is ...
