Oct 19, 2017#0183;#32;In our example, the grinding balls diameter needed to load into the mill must be equal to 4050 mm. Lets sum up. The grinding balls diameter determined by the Bond formula has a recommendatory character and serves as a starting point for calculating the necessary proportion grinding media feeding a new mill.
The FC Bond Mill was designed by F. C. Bond for use in determining the Bond Ball Mill Index, a measure of grindability and power required to mill various ores. FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bonds Method of Crushing and Grinding for determination of the Bond Index is included with each mill. This Ball Mill can be used continuously or it can be used for any number of
Vertical roller mills can typically handle an aggregate moisture of up to 20% in raw materials and consumes about 30% less power in grinding. Hence it is commonly preferred for grinding operation in new plants of higher capacities.
