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. This mill can be used to calculate the grindability of all ores.
This Ball Mill can be used in to grind for a period of time, if plugged into a lab timer, or it can be used for any number of revolutions, according to the type of grind desired.
