Technical Report: Effect of crusher type on the liberation of sulfur in bituminous coal Title: Effect of crusher type on the liberation of sulfur in bituminous coal Full Record

In this study, the effects at the three different coal size fractions on the five different characteristic coal samples depend on the performance of a crusher in the laboratory. Thus, a jaw crusher was investigated. Based on the results of the investigation, it was found that there is a great influence of coal feed size and coal type on crushing performance.

Geologists also classify coal types according to the organic debris, called macerals, from which the coal is formed. Macerals (microscopic organic constituents found in coal) are identified (microscopically) by reflected light the reflective or translucent properties of the coal .
