It is then carried through automatic weigher to transfer tower from where it is lifted and distributed between boiler hoppers by a conveyor.
The freshly mined coals that are fed to coal preparation plants are typically crushed to liberate rock before washing and to limit the largest size of particles that enter the plant. Operators prefer to keep the particles as large as possible (usually >50 mm) since fine coal processes are considerably less efficient and substantially more costly.
