Coal - Stone Source

Rawtech is a series of ink jet, colored-body porcelain tile with the look of unfinished, raw cement. The design approach captures the true identity of an essentially industrial product, and appeals to contemporary living styles. With intentional imperfections, it provides the look of a tile worn by time with an unmistakable style.

Density separation. Raw coal consists of organic and mineral matter components, with specific gravities ranging from 1.30 for the lighter organic material to 2.5 for rock. Coal is cleaned by separating the lower-density organic material from the higher-density refuse. In heavy-media separations, the specific gravity of the medium used for ...

Eliminating stone from the CPP feed is equivalent to an increase in plant capacity, ie. remove a tonne of stone from the feed and replace it with a tonne of coal. Put simply, using this sorting technique is attractive because it means that it is possible to put a higher quality raw coal through the CPP, which in turn means a higher yield.
