摘要
A method for reducing particle size of a particulate comprising feeding a feed material to a grinding mill having a power of at least 500 kW, the mill having a specific power draw of at least 50 kW per cubic meter of grinding volume of the mill and the grinding mill including a grinding media comprising particulate material having a specific gravity of not less than 2.4 tons/m3 and a particle size falling in the range of from about 0.8 to 8 mm, grinding the feed material in the grinding mill and removing a product from the grinding mill, the product having a particle size range such that D80 of the product is at least about 20 microns.
