OMC Power Model is OMC’sThe in-house software for specific grinding energy power-based circuit calculations. The model uses ore hardness parameters from testwork, QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE,Abstract: The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, time- consuming and requires trained operating personnel and therefore is subjected to errors. A

    Fred Chester Bond (June 10, 1899 January 23, 1977) which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third theory of comminution", counting those of Peter von Rittinger and Friedrich Kick as the first and second.
