Accurate to one ten thousandth of one percent. With
this new "Direct Reader" Spectrogr'apli, CF&I maintains
extraordinary control over each melt of steel.
Samples, taken from the blast furnace or open
heartti, are sped to the lab via pneumatic tubes. In
minutes, a complete spectrograptiic analysis is ready,
This "controlled chemistry" means Grinding Balis
and Rods that wear longer,, grind more efficiently.
What CONTROLLED CHEMISTRY
means in CF&I Grinding Balls and Rods
CF&I takes great care in the selection of steels used
in its grinding balls and rods. For example, each
size bail from the smallest to the largest (W to 5"
diameter) must have the proper composition to
give the best balance between hardness and toughness.
CF&l's modern spectrographic equipment assures
you balls with the correct chemistry in relation
to their size. In fact, CF&I uses different steels,
depending on the ball size required. This chemical
control pays off in your mill because CF&I balls
have greater resistance to abrasion, withstand
impact, and grind at lower cost.
In grinding rods, CF&I observes similar standards.
Special analyses of high carbon steels are
hot-rolled and machine-straightened to close tolerances,
from iy2" to 4" diameter in whatever lengths
ordered. CF&l's controlled chemistry techniques
result in grinding rods that have excellent wearing
properties, resisting bending or premature

A highly maneuverable crane-mounted radial press at Allis-Chalmers West
Allis (Wis.) Works drills holes in one of two 25-ft. diameter annular coolers being
furnished Humboldt Mining Co. The coolers will be used in conjunction with
first full-scale operafion of fhe gratc-kiln system in an iron ore agglomeration
process. The cooler grate sections, some of which are shown in place, tip' separately
at one point in fhe machine's cycle fo discharge completely cooled pellets.
