Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
It is highly configurable and available in a range of model sizes that will suit any hard rock or alluvial mining operation. With capacity range from laboratory scale up to 1000 tonnes of solids per hour, it combines centrifugally enhanced gravitational forces with a fluidised bed process to provide exceptional recovery of precious metals such as gold, silver and platinum group metals.
The 3D model in the saVRee database represents a vertical grinding bowl mill. Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and, roll and ring mill.
