The Cost of Saving Money in Coal Preparation Coal Age

Jun 19, 2014 In the 1970s, numerous cleaning plants were built with a twocircuit arrangement. The densemedia cyclone (DMC) was used to wash the plus0.5mm material and flotation was used to wash the minus0.5mm material. This arrangement saved money compared to using Deister tables on the small coal
