DEM Modelling and Simulation of Cone Crushers and High …

The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills. Circuits using Cone Crushers and High Pressure ...

GRINDING & POLISHING

Grinding/polishing pressure is dependent upon the applied force (Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (N/m2). For specimens significantly harder than the mounting compound, pressure is better defined as the force divided by the specimen surface area.
