Comminution operations are the most expensive and energy consuming in the mineral
industry. Any action aiming at reducing the costs associated with that step is welcome, and …

This first regional issue published in STMP highlights the potential and importance of the
research carried out in Latin America regarding surface engineering and tribology. In order …

This paper presents an experimental analysis, which was carried out to evaluate the
addition of nitrogen as an element complementing a chemical composition used for such …

The effects of different tempering temperatures (300–600° C) on abrasive wear resistance of
mottled cast iron were studied. Abrasive wear tests were carried out using the rubber-wheel …

Abstract A “Quenching and Partitioning”(Q&P)–based heat treatment has been applied to
rolled grinding steel (0.75 wt pct C-Mn-Cr) balls of 104-mm diameter to prevent their …

This article presents the results of applying a media selection methodology based on a
population balance model to a ceramic ball mill; the experimental data were obtained …

Mechanical properties, wear resistance and impact resistance of a high-alloy chromium cast
iron used in the fabrication of grinding balls have been studied. A rank of tempering heat …

The recovery of clean coal can be improved through grinding. In this study, grinding and
flotation experiments were conducted on difficult-to-float coal. Results show that the particle …

Different thickness coatings formed by multilayer laser cladding are widely employed in
laser repairing and the wear resistance of them are concerned. Multilayer nickel-based alloy …

A population balance model is applied to a steel ball mill. Experimental data were obtained
for two types of balls with different chemical compositions using a marked ball test in an …
