QUARTZ CRUSHING IN AUSTRIA
Liza.

The Ballarat Courier has the fol-
lowing interesting account of new
progress of quartz crushing: The
Nude Brothers, of Elaine, have
been for some time perfecting ma
chine which promises to revolutionize
present appliance, insomuch as it
lowers the cost of treatment, pulver-
Tres to a greater fineness and grants
facilities for more thorough ANAL
gamation Of the gold. The works
are situated near the north end of
that line of Elain gold bearing reefs,
the trend of which is marked by the
mullock heaps Of now defunct mines.
The Nude patent is remarkable for
its simplicity, and the appliance, it
is claimed, banishes at once any ne
cessity for a precise adjustment of
parts, and the great wear and tear
usually found in all pulverizers, out
side of the ordinary gravitation
stamper. It is simply an iron cradle.
For the sake of illustration, take an
ordinary steam boiler, say seven feet
long and two feet wide, and have it
cut in two--lengthways. Then take
one half and have some inch angle
iron run across it's bottom at two
feet intervals. In these intervals
place rollers, shaped like large
cheese, say one foot wide and one
foot six inches in diameter. Below
each roller, which occupies one foot
in two feet space, have quicksilver
rifles in the curve of the bottom,
and below these a grating-after the
first roller, (say,) thirty holes to the
inch, the second eighty, the third
two hundred and so on. The greater
the number of rollers the finer the
pulverizing. In the toe of the cra-
die have three or four ripples. These
iron cheese shaped rollers are very
heavy, being about half a ton each.
In Nudes machine there is about
two inches difference in the bed
levels of the different rollers, and it
was very surprising to note the ease
with which one man could set the
affair in motion, a motion which CEN
tered the effects of gravitation, NOM
entum, and the rebound of the rollers
onto the puartz, as the water and the
rocking bore it along under the diff
ferent rollers through the silver and
the gratings. 1t was also surprising
to note how thoroughly agitated the
quicksilver became, as it swung
backwards and forwards with each
roll of the cradle. With short
lever handle one man could work
the machine, and Mr.. Mudie's esti-
mate is that it will put through
twenty-five tons per week. The
whole affair appeared to be perfec-
ton itself, offering the maximum
facility in return for the minimum
effort, both in pulverizing and ANAL
gamating. A horse would work six
Of them, and according to Mr.
David Nudes calculations) could
get through over one hundred tons
per week. OF course the ordinary
tables or Frue vanner could be
fitted to it, but that would be decided
by the nature of the material to be
operated on. AS far as Nudes
plant is concerned, everything was
in very crude state, although they
have one machine in going form
AS with inventive genius all the
world over it has been a struggle
with them, intensified by want O.
means, and aggravated by the jeer'
Of the unsympathetic. Patient en-
durance and continuity of pur
pose have, however, brought then
through, and they have succeeded
in perfecting machine that will en-
able small cooperative party te
crush twenty-five tons per weel
with the aid of one man and boy
(using one machine) or company
to crush over 1900 tons by putting
an eight-horse power engene on t.
fifty of them. 1t IS simplicity itself
both in construction and it's mode O
action. 1t requires very little build
ing in, and child could manage
when in motion. The slightes
force keeps its pendulum-like SWIM
going, and it is claimed that tn
Nude Brothers have really hit on
most efficient while exceptional
economical applications of power.
