Analysis of the Particle Size Distribution of Products Crushing Shale and Dolomite Crushing by Compression of Single Irregular Particles

Inżynieria Mineralna, 2018
The paper presents the results of compression crushing tests of single particles for two lithological types of copper ore: dolomite and shale. The breakage test for single irregular particles were performed with using a hydraulic press device. The authors prepared five particle size fractions of each material, within ranges: 16–18 mm, 18–20 mm, 20–25 ...

CRUSHING STRENGHT DETERMINATION OF ROUNDED CERAMIC PARTICLES

, 1962
A test was performed to further define the mechanical properties of rounded ceramic particles. This test involves the measurement of the strength of individual particles under a compressive load using a standard compressiontesting apparatus. An average of several crush strength determinations is used to assign a compressive strength value to each ...

MHD Shock-Clump Evolution with Self-Contained Magnetic Fields

, 2013
We study the interaction of strong shock waves with magnetized clumps. Previous numerical work focused on the simplified scenario in which shocked clumps are immersed in a globally uniform magnetic field that extends through both the clump and the ...

Delayed crushing time for particles of rockfill materials

Yantu gongcheng xuebao
The delayed crushing of rockfill particles is specifically referring to the crushing of particles after loading for a certain period time, which is the basis for the rheological deformation calculation using the discrete element method (DEM).

Inhomogeneous Anisotropic Cosmology

, 2016
In homogeneous and isotropic Friedmann-Robertson-Walker cosmology, the topology of the universe determines its ultimate fate. If the Weak Energy Condition is satisfied, open and flat universes must expand forever, while closed cosmologies can recollapse ...
