Desliming Coal Processing

The desliming step increased the net tonnage to 923 th, a net gain of 24 th over the base scenario Case A. This represents nearly 6.5 million annually of additional revenues 24 th 6000 hyear 45ton 6.48 MMyear. Obviously, desliming to reject high-ash, high-moisture material is very attractive for this particular coal.

As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant line.
