The ratio of MgO/Al2O3 in the slag equaling 2.1 corresponds to the lowermost melting point of the slag resulting into a minimum of energy consumption for the portion of slag to be melted. However, due to the presence of some Cr2O3 in the slag and other oxides, MgO/Al2O3 ratio has the typical value of 2.2.
This processing plant is for the slag to recovery the Ferrochrome. The process is as below: The wheel loader or excavator feeds the raw slag to the hopper. There is an Electromagnetic vibration feeder under the hopper, which can feed the material to the belt conveyor more evenly.
