The Science of Comminution

In the present simulation rod-mill slurry density was controlled by maintaining stream 10 at a predetermined ratio with respect to stream 11. This leaves the four slurry densities, streams 3, 5, 8, and 9, to be controlled, but only two variables, the water-flow rates of streams 2 and 7, to be manipulated.

Comminution Testing – Core Group

Synopsis. A number of modern techniques suitable for the design of crushing and grinding circuits are described. The methods are based on extensive use of mathematical models of crushers, mills and classifiers and are seen as alternatives to conventional comminution design methods based on Work Indexcalculations.

Improving energy efficiency in comminution - MINING

The industrial comminution process under consideration has the following four units: Rod mill, Ball mill, hydro-cyclones, and water sumps. Fresh feed from the bin is fed to the rod mill along with water. The slurry generated from the rod mill is mixed with the slurry from the ball mill in a primary sump.
