<br />e <br /> <br />e <br /> <br />will be crushed in a series of four crushers to liberate magnesium metal <br />particles from the slag matrix. The liberated magnesium particles will <br />be separated from the slag matrix material by screening following each <br />crushing stage. Storage hoppers are provided between the crushing <br />stages, for slag dust residue and for magnesium granule product. <br /> <br />Course magnesium chunks separated at all four crushing stages will be <br />disposed of as magnesium scrap. Finer magnesium particles separated at <br />the fourth crushing stage will be further refined in existing equipment <br />to produce marketable magnesium granule products. This removal of <br />magnesium metal from the slag will reduce the reactivity of the slag by <br />seventy-five percent. <br /> <br />Slag dust generated at the primary crushing stage will be collected by a <br />venturi scrubber, producing an alkaline slurry which will be utilized in <br />the magnesium process. Slag dust from all other processing equipment <br />will be collected by three bag filter dust collectors. All process <br />equipment, with the exception of the primary crusher and scrubber, will <br />be located within a humidity-controlled building. <br /> <br />The third and fourth crushing stages and the bag filter dust collector <br />will generate 1,900,000 pounds per month of finely ground slag residue <br />for disposal. <br /> <br />EQUIPMENT LIST: <br /> <br />Slag Collecting <br /> <br />Molds <br />Dumpsters <br />Fork Truck <br /> <br />Building and Atmosphere Control <br /> <br />Crushing Equipment <br /> <br />4 - Crushers <br />6 - Screens <br />6 - Elevators <br />8 - Conveyors <br />Instrumentation <br /> <br />Dry Material Storage <br /> <br />5 - Hoppers <br /> <br />A-5 <br />
