1 Coarse crushing: After mining, large dolomite rock enters a jaw crusher for coarse crushing. 2 Fine crushing: Then the dolomite rock enters a cone crusher for fine crushing. It is crushed into dolomite blocks of small particle size to achieve sufficient dissociation of the useful material of the ore. 3 Screening: The crushed dolomite blocks ...
The kilowatt-hours per tone (kWh/t) will work out your work index. The number of kittowatts consumed in a hour divided by the tonnes of rock gives you your work index. Remember, the higher the Work Index the more work required to crush the rock. This will impact the equipment chosen for your project.
The Dolomite occupies approximately 2% of Earth's crust. Dolomite formation occurs under anaerobic conditions. The mineral occurs in the form of dolomite marble, dolomite carbonatite, and dolomite-rich veins. Magnesium in Dolomite can be substituted by other cations like ferrous iron, lead, barium, zinc, and manganese.
