Fine Grinding of Coal by the Turbomilling Process.

Both "plantgrind" size (80 pct minus 75 um) and microsize (minus 10 um) coal can be produced in a single step with the Bureau's turbomill. In 15 min, minus 2.4Mm coal milled in water with steel shot was reduced to 65 pct minus 75 um and 26 pct minus 2 um, with an energy requirement of 139 kw.H/mt coal.

Effects of Grinding Process on the Properties of the Coal

The grinding process is necessary to convert original coal bottom ash (CBA) into a powder form. The aim of this study is to evaluate the grinding process effects on physical properties of CBA, it influences on consistency and setting time of cement paste and to predict it potentiality based on chemical characteristics to reduce the alkalisilica reaction (ASR) in concrete.
