Gyratory crushers are generally used for primary crushing, and cone crushers are used for secondary and tertiary fine crushing ...
The EPA compared the data from this analysis to the national average for each of the demographic groups. Since the taconite iron ore processing facilities are very large, a radius of 10 km was used as the near facility distance for the proximity analysis. A distance closer than 10 km does not yield adequate population size for the results.
Nuclear Materials Facilities (by Location or Name) The U.S. Nuclear Regulatory Commission (NRC) currently regulates fuel cycle facilities and uranium recovery facilities in Illinois, Nebraska, New Mexico, North Carolina, Ohio, South Carolina, ia, Washington, and Wyoming.
