  Coking Pressure Control by Selective Crushing of High …

  crushing of coal in order to reduce coking pressure has not been positively used on a commercial scale. In the current work, firstly we investigated the effect of the fine crushing of coal on coking pressure under the same coal charge bulk density through use of a test coke oven. Then, we developed a method to measure plastic coal layer

  Chapter 4 The Principles of Single-Particle Crushing

  200711 · This chapter deals with “single-particle crushing” as an important microprocess in the field of comminution. The term “crushing” is related to a certain kind of comminution. It depends on the material properties and the grain size distribution of the feed and/or the product. It is a part of the macroprocess that happens inside the ...

  Effects of rock types and crushing mechanism on the 3D …

  This study aims to investigate the effect of rock types, i.e., granite, conglomerate rock, limestone, and crushing mechanism, i.e., Vertical Shaft Impact (VSI) crusher, Horizontal Shaft Impact (HSI) crusher, on the morphology of manufactured sands. By combining the 3D scanning and spherical harmonic analysis, the morphological parameters of …

  The Energy Principle of Coal and Gas Outbursts: …

  2020923 · Outburst energy is a major factor influencing coal and gas outbursts, albeit its estimation is difficult owing to the lack of amenable means for quantification of gas desorption. In the past decades, determining the mechanism of outbursts is one of the most challenging issues in rock mechanics. In this study, a triaxial coal and gas outburst …
