Read MoreAug 14, 2017 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.
Read MoreThe Bond ball mill grindability tests were conducted for the untreated and microwave-treated (2.45 GHz, 1.7 kW) quartz and calcite representative samples. The findings showed that the Bond work indices of the untreated quartz and calcite are 11.49 kWh/ton and 5.21 kWh/ton, respectively.
Read MoreThe ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
