THE SUMPTER MINER
Machine to Take the Place of
Last week THIi MINER published a
short description of a device known as
the pneumatic pulverizer, deigned to do
the work of a stamp mill. Its tir.t public
test was given at Seattle last week. The
Mining Record of that city devotes much
space to the subject, it asys that more
that 200 mining men from all over (lie
Northwest were present at the time, and
manifested much satisfaction over the re
The great distinguishing feature of the
pneumatic pulverizer is that substances
are powdered by being shot against rich
other at a terrific velocity by means of op
posing jets of steam or compressed air.
At a pressure of too pounds to the square
inch superheated steam or compressed air
is allowed to escape through two three-eighth-inch
nozzles, directly opposed to
each other and separated by an lutervei,
ing space of some eight inches. The jets
of air or steam then pass respectively Into
and through two funnel shaped apertures
that gradually reduce to a five-eighth-Inch
diameter at the inner opening. The
inner openings are three inches apart,
terminating In a bowl shaped cavity.
After being reduced to the size of peas in
an ordinary rock crusher the material to
be pulverized is fed, from two hoppers,
into an enclosed space surrounding the
ends of the nozzles and funnels.
Here the suction of the two powerful
jets of steam or air catches the material,
and, drawing it into the end of the fun
nels, forces It in two compact streams of
solid substance, through the five-eighth-Inch
orifices to meet each other midway in
the bowl-shaped receptacle. The velocity
of each stream of material is 3,000 feet per
second, a speed equal to, or greater even,
then a Mauser bullet. This terrific im
pact reduces the material to a powder finer
than wheat flour.
A pneumatic elevator, a vacuum stack,
removes this powder as fast as it Is pro
duced, carrying it to bins, from which it
can be drawn off through gates or chutes.
The suction of the pneumatic elevator Is
so regulated that it will carry away only
powdered particles, coarser particles tail
ing back to again be fed Into the machine
by a simple device. After being reduced
to powder, oris ar then treated as In oth
er reduction processes.
The pneumatic pulverizer works
equally well with superheated steam or
compressed air. Wherever a water power
exists one or more of these machines can
be operated successfully. The machine
does not weigh more than an upright
piano. It can be taken apart, the heavi
est piece weighing but 42 pounds; hence
it can be taken anywhere that a mule or
a man can carry a small pack. The ad
vantages of the pneumatic pulverizer over
stamp mills and other machines may be
enumerated as follews:
They can be taken anywhere on the
shoulders of men or pack mules.
They require no special foundation for,
there being not a particle of jar or strain,
they operate equally well resting on the
bare earth or on thin boards.
The first cost Is less than one-half the
cost of stamp or other mills of equal ca
pacity. The expense of operating the new ma
chine is less than so per cent of the cost
of operating stamp mills.
Vexed Question of Mining Taxation.
The vexed question of the valuation
and taxation of mining property has come
again, this time In New Jersey. The as
sessors of Sussex county In that state
hive been for several years trying to!
raise the valuation of the property of the !
New Jersey Zinc company In the town
ship of Htirdlston; but their arbitrary In-'
creases have been set aside by the courts,
chiefly because there is no statutory pro-1
vision in that state for the valuing or ta.
Ing minerals undergiouud. This ye.ir the
matter has been fought over again, the
county assessors, the siate board of tax
ation and the company all taking part,
l-'lnally a compromise was reached bv
which the valuation of the company's
mines was increased by $420,000, or about
50 per cent. This still leaves the ques
tion in a verv unsatisfactory state. I he
valuation is a purely arbitrary one, and In
New Jersey, as in many other states, no
one seems able to determine the just or
rational basis on which mining property
should be valued for taxation purposes.
