The FC Bond Work Index Test Ball Mill was designed by F C Bond for use in determining the Bond Index a measure of grindability and power required for grinding applications The FC Bond Mills are used in laboratories throughout the world A copy of Fred C Bond’s Method of Crushing and Grinding for determination of the Bond Index is included with each mill

The Bond ball mill work index is one of the most commonly used grindability tests in mining and is often referred to as the Bond work index The test is a lockedcycle test where ground product is removed from test cycles and replaced by fresh feed The test much achieve a

According to the Bond standard procedure the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250 circulating load Bond 1949 1952 1961 The test is performed on a raw material approximately weighing 10 kg which coarseness is 100 3327 mm

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250 is developed It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling

It is commonly known that one must run the Bond ball mill work index test such you pick a closing mesh to give a P80close to desired grind size This is because work index frequently changes as a function of the product size in comminution
