Experimental Study on Limestone Cohesive Particle Model and Crushing
The simulation model follows the same process as the impact crushing experiment. Results show that, after crushing at impact velocities of 30 and 40 m/s, the simulated particle-size distribution curve matches experimental results as closely as 95%. For different particle sizes, results are more than 90% in agreement.

HPGR High Pressure Grinding Rolls
HPGRs produce a product with substantially more lines (for a given P80) than a crushing circuit. In this regard, the size distribution of an HPGR circuit is much more similar to the product of an SAG circuit than a conventional crushing circuit, reducing the amount of pow'er in the ball-mill circuit required (relative to a crushing circuit).

Crushing simulation using an energy-based damage model
During the simulation, on the crush front (contact between wedge-shaped tip composite plate and the metallic crushing plate), just after the onset damage for each one of the five failure modes (Fig. 2a), the damage parameter is low and hence the degradation of this element and consequently, its distortion, is low as well.
