bins hold bulk goods temporarily.
Bins associated with ore trestles are common at
smelters (Figure A-17 thru A-37).
(5) Pipelines, conveyors, cranes, and mobile equipment are used to handle or
transport materials.
Pipelines are common but not in great numbers.
Conveyors,
either inclined or horizontal, housed or open, handle bulk materials between
storage areas and processing buildings.
They usually appear wider than pipelines
and have flat surfaces.
Overhead traveling cranes handle ores and finished
products.
Mobile equipment, such as bulldozers and trucks, handle bulk materials
(Figures A-38 thru A-52).
(6) Complex equipment includes the pipe-like cooling tubes at zinc oxide
plants, and the blast furnaces, hot stoves, and dust collection equipment found
with iron smelters as well as transformer yards and outdoor boilers (Figures A-53
thru A-59).
b. Buildings are presented in three subdivisions based on function.
These
subdivision are processing, storage, and administration. The Image components are
somewhat different for each subdivision.
Certain buildings associated with other
image components will provide the identity of the industry.
(1) Processing buildings are divided on the basis of relative size into small,
medium, and large.
The buildings are better ventilated, and larger and more
massive in appearance than those in the other categories (Figures A-62 thru A-73).
(2) Storage buildings are served by rail lines or roads.
Covered ore bins
found at smelters are among the more important storage buildings associated with
heat processing industries (Figures A-74 and A-75).
(3) Administrative buildings usually are built to one side of the plant area
near the main entrance and served by walks, driveways, and parking areas.
The
grounds around them may be landscaped (Figures A-76 and A-77).
c. Open storage and waste appear as piles. Very few ponds will be seen in this
category.
Piles of coal, limestone and ore, as well as metal products, often
stored in crane-served yards, and large and conspicuous waste piles frequently are
associated with the metal smelting and refining industries (Figures A-78 thru A-81).
REMEMBER:
The size and arrangement of stacks are of primary importance in
analyzing heat processing industries. Large complex equipment such as
blast furnaces are specific identification features of heat processing
industries.
Open storage and waste, as well as the design and
arrangement of some of the buildings, are helpful in confirming the
analysis of an industry. Conveyors and pipelines are especially useful
when analyzing the succession of processes and operations.
