A new approach to the calculation of bond work index for finer samples
Berry and Bruce (1966) and Horst and Bassarear (1977) devised an approximate procedure comparing the grindability data of an unknown ore with a reference ore whose grindability data are known and determined in a Bond ball mill. The test is performed on samples of size − mm in any laboratory mill with balls.

A ball mill consists of a horizontal revolving cylinder containing a charge of tumbling or cascading balls, pebbles or rods. As a very rough indication, ball/rod charge may occupy 2550% of the total internal volume of the mill. The lengthtodiameter ratio of such a cylinder usually is between 2:1 and 3:1. Ball mills can perform wet or dry ...

Ball Mills Mt Baker Mining and Metals
The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering your grinding circuit.
Energy efficient cement ball mill from FL
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
Mesh (scale) Wikipedia
Mesh (scale) Mesh is a measurement of particle size often used in determining the particlesize distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
