ON CENTRAL UPUFTS IN THREE TERRESTRIAL CRATERS. .
inferred that comminution takes place during the flow of debris following passage of the shock wave. The rocks at the center of the crater are so well confined that they flow only a small distance and strains are small. Rocks at the periphery or even off center at the bottom of the excavation are subjected

Tunnel rock recycling Wikipedia
At a certain stage in the comminution, the rock material fragments down to free minerals grains as free Mica or Quartz minerals. In Figure below are the different crusher types listed. For cubification of the rock, the Vertical shaft impactor (VSI) is a suitable crusher. The technology lets the rocks collide with each other and split at the natural cleavage lines.

Comminution | Definition of Comminution by Lexico
'Preliminary treatment includes such operations as flow equalization, screening, comminution, grease removal, flow measurement, and grit removal.' 'It is likely that this is a result of their being much more resistant to abrasion and comminution in moderately coarsegrained, higherenergy environments.'

Modeling the comminution and flow of granular brittle material
Penetration weapons or explosive charges in brittle materials (such as ceramics or hard rock) cause fracture and fragmentation near the cavity boundary to produce a bed of fragmented or granulated material. Subsequent large shear deformation and flow of the granulated material occur under confining pressures that range from many GPa to zero.

finite element program. The present theory is inspired partly by Grady's model for comminution due to explosion inside a hollow sphere, and partly by analogy with turbulence. In high velocity turbulent flow, the energy dissipation rate gets enhanced by the formation of microvortices (eddies) which dissipate energy by viscous shear stress.

COMMINUTION Comminution conundrum
comminution energy – a cost that increases exponentially as product size decreases. In Australia, for example, since the 1970s the standard feed size for mineral beneficiation has dropped from 74 microns, to 38 microns in the 1980s, to less than 8 microns in the 1990s in a number of major mining operations. These deposits require fine and ...

We examined the adsorption kinetics of αchymotrypsin (pH, 102 to M Tris buffer) on muscovite mica in conditions of laminar flow through a slit. The range of buffer concentrations is between two limits: (i) no adsorption in 1 M Tris and (ii) no desorption in 103 M Tris. Studying the dependence of adsorption kinetics on the wall shear rate leads to the determination of the ...
