ABSTRACT:
A crushed raw coal washing plant using a plurality of deflector-fitted centrifugal cyclones to produce a washed and dried mixture of clean coarse and fine coal, and fine coal alone, with means to remove refuse and means to recycle clean fine coal slurry by-product into the raw crushed coal inlet. Each centrifugal cyclone of said system is fitted with an inlet line deflector and equalizer means to create laminar flow and gravity separation whereby low density (1.6 or less) washed coal escapes through a first outlet at the top and refuse drains out of a second outlet at the bottom of said cyclone.
