A New Ore PuIverlzer.

| "A party OF saginaw stOCKnOluefs, VINO
arrived in Custer the latter part of last
week, were guests of Manager Wood
bury, and during their stay they spent
most of their time at the Saginaw mine.
Their names and residence are as fol-
lows: Geo. S. Thompson, Columbus,
Ohio; l. w. Herber, Elkton, Michigan !;
Frank Price, Columbus, Mich. Geo. z.
Good, Detroit, Mich.
The mission Of Mr.. Good in the Hills
at this time was for the purpose of in
PRODUCING new machine which he has
invented, designed for fine crushing and
is called the National ore pulverizer
These machines are manufactured by
the firm of w. L. Mccullough company,
whose works and general sales Office is
located at Detroit, Mich. Mr.. Good is
mining engineer of long experience in
the mines of America, Mexico and Cen.
tral America, having made study of
mines aud mining machinery since 1870.
He is also an analytical chemist Of note,
and has held many important positions
as mining engineer and manager of
mines. We make mention of this, as
almost the first question a mining man
asks concerning a person who comes
with a new mining device is, does he
know anything about mines and mining
machinery? The answer to this ques.
ton is, if he don't know he certainly
ought to know, after all the experience
ald hard work he has put into the busi-
ness. AS the experience of the writer
dates back to the beginning of quartz
mining in Colorado in 1860 our endorse.
ment of Mr. Goods machine should do
him some good, and we give it cheerfully
after due examination without solicit
tation or hope of reward
Lack of space precludes our giving a
minute description of the machine at
this time but we will say after having
looked into its merits carefully, that in
our opinion, the National ore pulverizer
is superior to anything we have seen for
the purpose for which it is designed. 1t
has been introduced and is now in use
in several mills in Mexico and the Unit
ed States where the parties operating it
testify that with 25-horse power it will
crush any ore (even the hardest) at the
rate Of from 10 to 100 tons per day, and
if desired will make it as fine as -four.
The ore enters the mill between two
disks which revolve in opposite direc-
tions one concave and the other convex
and they are set by a screw, close or
wide, according to the fneness desired
1t is recommended that where very fine
grinding is desired the three machines
be set up so that continuous flow may
be kept up passing from one to the other
until the desired fineness has been OBJ
tanned. In this way ore may be crushed
to any mesh required at the rate of six
tons per hour. The first machine is run
with s horse power, the End by 5 5and the
3rd by horse power. A small model
machine was set up at the Saginaw and
tested with power attached and ii proved
a surprise to all who saw it operate We
understand that Mr.. Woodbury. will
adopt it in the new mill which the Sagi-
nav company will erect in the near fut-
ure OF course we are aware that there
have been in the past, fifty or more ma
chimes invented and tried with the
avowed purpose of superseding the old
stamp mill and thus far without success
That is for the purpose for which the
stamps were originally designed, and
that is to catch the free gold on copper
tables by amalgarnation with mercury.
yet. We see no reason to think that it
has. We speak of this machine as a
pulverizer and nothing more, and as all
ore has to be pulverized before it can
be treated either by the amalgamation,
chlornation or cyanide, we think that
the National pulverizer has come to fill
long felt want. Mr.. Good and his
company has a world wide field in which
to operate, and we believe it will prove
success.
Mr. Woodbury. and his guests depart
ed on the train for Deadwood and Lead
on Tuesday, where Mr.. Good will inter-
view the mill men of the northern Hills
and discourse on the merits of his ma
chine.
