The energy-size reduction relationships in comminution of solids
TLDR
In this paper, a new derivation of the Charles energy-size reduction relationship was presented, which matched the moments of particle-size distribution from the grinding equation with those computed from the empirical Gaudin-Schuhmann size distribution equation.About:

Cataclasis and processes of particle size reduction
TL;DR: In this article, Anderson et al. showed that the fractal dimension (D) of fragmented geological materials is affected by the fragmentation process, initial size distribution, number of fracturing events, energy input, strain, and confining pressure.
Journal ArticleDOI
Self-preserving size spectra of comminuted particles
TL;DR: In this paper, three pertinent aspects associated with grinding of brittle solids, namely, grinding kinetics, particle-size distributions and energy-size reduction relationships have been unified in the framework of a phenomenological model of particle size reduction.
Journal ArticleDOI
An application of breakage mechanics for predicting energy–size reduction relationships in comminution
TL;DR: In this paper, a breakage mechanics model that accounts for the evolution of the grain size distribution (GSD) due to comminution with only five parameters, all of which are physically meaningful, is proposed.

A combined thermo-mechanical drilling technology for deep geothermal and hard rock reservoirs
Edoardo Rossi,Shahin Jamali,Volker Wittig,Martin O. Saar,Martin O. Saar,Philipp Rudolf von Rohr +5 more
TL;DR: Combined thermo-mechanical drilling is a novel technology to enhance drilling performance in deep hard rock formations as discussed by the authors, which can increase the removal performance in hard rocks by up to a factor of three, compared to conventional drilling methods.
Journal ArticleDOI
Field test of a Combined Thermo-Mechanical Drilling technology. Mode I: Thermal spallation drilling
TL;DR: In this article, a Combined Thermo-Mechanical Drilling (CTMD) technology is proposed, which employs a heat source (e.g., a flame jet) and includes two main drilling modes: thermal spallation drilling and flame-assisted rotary drilling.

A solution to the batch grinding equation
TL;DR: In this article, a practical approximation to the fundamental integro-differential equation for batch grinding is presented and a solution is developed in terms of two experimentally determined basic parameters of the system, rates of breakage and breakage function, and is in a form suitable for simple extension to describe continuous grinding systems.

Fracture of Brittle Solids. II. Distribution Function for Fragment Size in Single Fracture (Experimental)
J. J. Gilvarry,B. H. Bergstrom +1 more
TL;DR: In this paper, the theoretical results of Gilvarry for the size distribution of the fragments in single fracture have been verified experimentally by fracturing spherical glass specimens under compression, where fragments were contained by a gelatin matrix to inhibit secondary fracture and thus conform as closely as possible to single fracture.
