"We take of this raw feed and segregate it out by size fraction and wash it to get optimum yield," said Peters ...
The term coal handling and processing plant (CPP or CHPP) is today often used to describe a coal washing plant (Fig. 12). Since the processes in such a plant are largely comparable, more and more standardized plants (MCPP, M = Modular) are being built. Their screening devices serve for classification of the coal size fractions and for dewatering.
