Particle grinding is a final stage in the comminution process used to liberate minerals from gangue in mineral processing plants. Semiautogenous grinding (SAG) occurs in tumbling mills which use both large ore particles and steel balls for grinding. Grinding is the most energy intensive mineral processing unit operation and hence its optimisation is of considerable interest to industry ...

Emissions factors from [26] were used for each travel segment. (In future research, truck emission factors will be based on [34].) Because these emissions factors are normalized by load, they had to be adjusted to determine actual CO2 emissions by assuming that the ocean freighter and diesel truck utilization were both 75%.

Grinding mills generally use impaction rather than compression. Reduction by impaction will produce a larger proportion of fines. Particulate emissions are generated from grinding mills at the grinder's inlet and outlet. Gravity type grinding mills accept feed from a conveyor and discharge product into a screen or classifier or onto a conveyor.
