SIfARPLES CREAM SEPARATORS
AND TUBULAR SUPERIORITY.
Centrifugal 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 1;o give
the same circumferential speed.
The increase of three times as many revolu- |
lions 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 '/s 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. j
Some manufacturers use complicated inter- j
nal devices to increase capacity, we accomplish |
a better result by the simple scientific method |
of reducing diameter and increasing revolu- J
tions. In this way, we preserve simplicity and ||
durability, make a bowl weighing thirty pounds II
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 tendenc3'
break the globules. • sftjjjmh.
