At the VRM200 the classifier operates most efficiently between cut sizes (d98) from 70 to 100 μm, while the classifier on the VRM600 is optimized for d98 from 10 to 25 μm. On the other hand the much higher throughput rate and restrictions in experimental time confined the

CONSIDERATIONS ON THE CRUSHING TEST FOR

The findings of tests on the crushing coefficient of rocks of different lithologic type, indicate that the coefficient is influenced by varying the initial grain size composition within a prescribed range. The extent of this influence is dependent on the type of material, and the standardisation of a reference grain size distribution is therefore proposed to eliminate any bias.

Micromechanics of pressure‐induced grain crushing in

1990-1-10  The critical pressures for grain crushing in our sandstones range from 75 to 380 MPa. In general, a sandstone with higher porosity and larger grain size has a critical pressure which is lower than that of a sandstone with lower porosity and smaller grain size. We formulate a Hertzian fracture model to analyze the micromechanics of grain crushing.
