More## The Importance of Work Index in Mineral Processing

The kilowatt-hours per tone (kWh/t) will work out your work index. The number of kittowatts consumed in a hour divided by the tonnes of rock gives you your work index. Remember, the higher the Work Index the more work required to crush the rock. This will impact the equipment chosen for your project.

More## Index Minerals Defined and Explained in Geology

25/02/2019 Geologists look at the minerals in rocks to determine how much heat and pressure — and thus how much metamorphosis — the rock has undergone. Certain minerals, called "index minerals," only appear in certain rocks at certain pressures, Thus, index minerals can tell geologists how much the rock has metamorphosed. Examples of Index Minerals

Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced

More## A New Approach to the Calculation of Work Index and the Potential Energy of a Particulate

The work index Wi was defined by F. Bond as the specific energy (kWh/ton) required to reduce a particulate material from infinite grain size to 100 microns. The calculation is based on the size-energy relationship e1,2=C.(1/x2n–1/x1n ) , which for n = 0.5, x1 = ∞ and x2 =100, by definition gives e∞, 100 = Wi and consequently C=10Wi. In theory, for a given material the value found for Wi ...
