Coarse Coal Centrifuge - Alejandro FB05

Together, the coarse and fine inert materials are referred to as coal mine waste. Separately, they are referred to as coarse and fine coal refuse. Coarse refuse is transported to a disposal facility by truck or belt line. Fine refuse typically exits the separation process in slurry form and is disposed of in abandoned mine

Company Presentation - Energy

WOCs possess many advantages in coarse coal slime separation, including no media consumption, small installation area, large processing capacity, no moving parts, and low operational expenses (Dong et al., 2013, Hacifazlioglu, 2012a, Hacifazlioglu, 2012b, Majumder and Barnwal, 2011). However, poor separation accuracy is an evident disadvantage ...
