calorific value is approximately 8000 kcal/kg. The content of sulfur in petroleum coke depends on the sulfur content in crude oil. Petcoke is generally more finely than coal, so there is no need for a pre grinding before storing and sending to the mill. Hardgrove grindability index (HGI), of coke and lignite are roughly the same, although coke ...

The process gases taken into the mill carry the ground material to the integrated classifier. The required target fineness is set by adjusting the classifier accordingly. Coal/petcoke is dried by hot gases taken into the mill. The temperatures in the grinding circuit are reduced by water injected into the grinding zone.
