FC Bond Ball Test Mill | Sepor, Inc

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. Bond's Method of Crushing and Grinding for determination of the Bond Index is included with each mill.

Where, y is cumulative percent passing size d, d 50 is the 50% passing size, n is distribution constant, and k is a correction factor. The n values ranged from 0.84 to 1.84, and k values from 0.95 to 1.00. By using the Bond method of grindability, H. Ipek et al. [4] have observed that less specific energy input is required in separate grinding of ceramic raw materials than grinding them in

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
