coal slag reclaimation

slag-utilization | netl.doe.gov

Helps the economic competitiveness of coal, in general, and integrated gasification combined cycle (IGCC) processes in particular. The interest in using slag is largely driven by the avoided landfill cost 1. Avoided landfill costs can be significantly different for utilities with and without captive landfills.

Steel Grit Vs Coal Slag Blast Media

Steel Grit Pros. It's a harder more productive blast media – Steel grit is harder compared to coal slag, this extra hardness allows you faster blast production times because the extra hardness will take deposits off of substrates quicker. In some cases it will remove deposits that may not be easily freed from a substrate with a coal slag media.

Coal slag VS Aluminum Oxide for Sandblasting

Coal Slag is one of the most readily available blast medias in most areas. It is ideal for removing medium – Heavy amounts of paint and for prepping surfaces for coating application for a profile range of 2- 6 Mils depending on the coarseness of media used. It turns to dust on impact which can help with clean up if reclamation is not important.
