A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes. Fine coal ...

The spiral performed well in cleaning the coarse 8 x 16 mesh size fraction, as demonstrated by the Ep ranging from 0.091 to 0.177. This is in line with typical spiral performance. In addition, the presence of the coarser size fraction did not significantly affect spiral performance on the typical 16 x 100 mesh fraction, in which the Ep ranged ...

WesTech's coal preparation technologies clean and separate coal-rich matter from mineral-rich particles by size. This preparation increases the quality and commercial value of saleable coal by reducing 75-80 percent of the ash and reducing 15-80 percent of the trace elements. By using prepared coal, transportation costs are lowered, and the ...

Coal preparation, or beneficiation, is a series of operations that remove mineral matter ( i.e ., ash) from coal. Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

As finer sizes of coal are washed, new techniques will be used. In the accompanying flow sheet for the Homer City coal-washing plant of the Penelec Co. shown as Fig. 6, there is a heavy-medium cyclone which receives the underflow of a 2 mm x 0 classifying cyclone which makes a split at 100 mesh. Thus, the cyclone input is sized at 2mm x 100 mesh.

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's …
