Moisture in Coal, Coal Analysis, Kentucky Geological ...

Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals. Moisture adds weight to coal, and also contributes to spontaneous combustion in low-rank coals, and as such, affects handling and transport. Moisture can ...

Rotating Probability Screens for Steam Coal Preparation

The traditional method of removing fine coal such as ¼" x 0 from overall 4″ x 0 raw coal is to use a vibrating screen at about 900 RPM. However, since the advent of the continuous and long wall mining methods, more water is required to suppress dust at the mine face. As a result, the raw coal contains surface moisture exceeding 4% or 5%, which makes the screening difficult. The enlarging ...
