SIARPLES CREAM SEPARATORS
AND TUBULAR SUPERIORITY.
Ceutrif ug'al Force varies directly as the diam
eter.
Centrifugal Force varies as the square of the
revolutions.
A 4 in. diameter bowl will need three times
the revolutions of a 12 in. diameter bowl to give
the same circumferential speed.
The increase of three times as many revolu
tions would give 3X3 = 9 times the centrifu
gal force if the bowls were of the same diam
eter. But the higher revolution bowl is but '/$
the diameter of the larger, so the smaller diam
eter bowl will have but of 9 times or 3 times
the centrifugal force. Thus a bowl 4 in. diam
eter running at the same circumferential speed
will have three times the centrifugal force of a
bowl 12 inches in diameter.
Three men will lift a stone which one man
cannot budge. Three times the centrifugal
force will recover small cream globules that
otherwise cannot be separated.
Some manufacturers use complicated infer
nal devices to increase capacity, we accomplish
a better result by the simple scientific method
of reducing diameter and increasing revolu
tions. In this way, we preserve simplicity and
durability, make a bowl weighing thirty pounds
do more work than any other bowl of three
times the weight, and produce a cream unequal
ed in smoothness and value, because it goes di
rectly through an unobstructed
bowl, thus obviating any tendency K
break the globules.
