HAER No. PA-115<br />
(Page 66)<br />
building was designed and manufactured by Canadian Met-Chem<br />
Consultants Limited of Montreal, Quebec.<br />
Construction date: 1980.<br />
C. Hot Metal Track: The track running through the iron<br />
desulfurization building becomes a hot metal track leading to the<br />
basic oxygen steelmaking shop after it leaves the building.<br />
Installation date: 1980.<br />
VIII. Ferromanaanese Preparation, Storage, and Delivery<br />
Facilities:<br />
A. Primary Ferromanaanese Crushing and Conveying Line:<br />
Travelling in a west to east direction, the primary<br />
ferromanganese crushing and conveying line is located 27 0'-0"<br />
north of the ferromanganese car preparation building. The line<br />
consists of a 7'-0" high steel framed platform straddling a<br />
standard gauge railroad track at its far western end; a motor<br />
driven 36" x 15'-3" Pioneer Oro Feeder leading to a 24" x 36"<br />
Pioneer Jaw Crusher driven by a 150 hp motor capable of crushing<br />
125 tons per hour; and a 30" x 46 , -0" motor driven conveyor belt<br />
extending from just below the jaw crusher and rising at a slope<br />
of 10 degrees.<br />
Installation date: 1965.<br />
B. Secondary Ferromanaanese Crushing and Conveying Line: The<br />
secondary ferromanganese crushing and conveying line is laid out<br />
parallel to and 19'-0" south of the primary line. It consists of<br />
a T'-O" high steel framed platform straddling a standard gauge<br />
railroad track at its far western end; a 25 hp motor driven 3 6" x<br />
12'-3" Pioneer Oro Feeder leading to a 125 ton per hour 150 hp<br />
motor driven 24" x 3 6" Pioneer Jaw Crusher; and a steel framed<br />
3 0" x 50'-0" motor driven conveyor belt extending from just below<br />
the conveyor belt and rising at a slope of 10 degrees.<br />
Installation date: 1955.<br />
C. Crushing and Screening Control House: An approximately 8'-<br />
0" square x s'-O" high corrugated metal control house sits on a<br />
raised platform between the primary and secondary crusher.<br />
Construction date: 1965.<br />
D. Ferromanganese Conveying, Screening, Storage, and Delivery<br />
Itine.: The 250'-0" long ferromanganese conveying, screening, and<br />
storage line is laid out perpendicular to the primary and<br />
secondary lines at their eastern end and travels southward to<br />
within 20*-0" of the ferromanganese car preparation building's<br />
north wall. It consists of a steel framed 30" x 250'-0" motor<br />
driven conveyor belt extending from below the primary and<br />
secondary line which rises at a slope of 10 degrees; a three grid
