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.
