BUNKER HILL SHELTER
INCREASES CAPACITY
IMPORTANT ADDITIONS BEING
MADE AND IMPROVED "a.
clLlTiES PROVIDED.

iSANcusiNe duuitlOHS anu improve
ments are being made at the Bunker
Hill smelter, according to the KEEL
logg correspondent OF the Spokane
Chronicle, which when completed
will practically double the smelling
and refining capacity of the plant.
These changes are described in con-
siderable detail as follows:
Enlarge Furnace Building.
Foundations for a 72-foot extern
sion to the furnace building are now
completed and this will provide room
for two additional blast furnaces,
During the last few months three
Dwight Lloyd sintering machines
were added to the original roasting
plant and construction work is now
under way for two additional ma
chimes. When these are completed the
smelter will have nine of the stand
ard Dwight-Lloyd machines in oper-
alton. The blower house has recent
ly been doubled in size and a Con-
nersville blower of $4,000 cubic feet
capacity has been installed in the ex-
tension.
Add to Lead Refinery.
"In addition to this a new COM
pressor room has been completed and
a Sullivan two-stage compressor of
100 cubic feet capacity installed In
In Ia ur-1
Gordon compressor Is being installed,
to be used as an auxiliary unit when
needed.
According to Walter X. Mallette,
construction engineer, who has been
with the big plant since its early be-
ginning and who Is now in charge of
charging the smelter, the most no.
ticeable piece OF construction during
the last month is the extension to the
lead refinery. This Is being enlarged
by the addition of 70 feet on the west
side of the original refinery. The re-
torts have been removed from the sill
yer refinery and are temporarily set
up in the lead refinery.
New Softening Furnace.
"A new softening furnace has been
built west of the original No. soft
ener, and two additional desilverizing
kettles are planned. These changes
will materially INCREASE the capacity
of the lead refinery. Two new cupell-
ing furnaces have been built in the
silver refinery in the space formerly
occupied by the retorts. These cupels
are much larger than the original
double furnace and have added ma
terially to the capacity of this depart
ment.
"In the furnace building second
travelling crane is to be installed, so
that one may be used for the refinery
New Tracks Being Built.
ITO facilitate the handling of the
equipment and provide for use OF
machinery as far as possible in all OF
the work. two additional tracks are
in the course of construction across
the gulch south of the sample miii'
and another row of bins will be served
nv these tracks. Mr.. Mallette states
that these bins will be provided with
a belt conveyor and feeders from
which the charge of the roasters will
be made I'D. One of the lines of track
will run clear through the plant. Ihls
will provide through track, when
will not be blocked by cars at any
time, and greatly facilitate handling
equipment.
Had to Move Shop.
'In order to run this track through
the plant, Mr.. Mallette says 1t De-
came necessary to move both the main
shop and warehouse sites. AS re-
suit, an entirely new shop building is
now nearing completion just south OF
the old shop. The new shop embraces
machine shop, 4Sx64 feet; a torge
shop, 32x4S feet, and boiler shop 40
YEA feet. These are all equipped with
the most modern tools, are served pv
hand operated cranes and furnish
complete equipment for all repair ana
imnrovement work A two story, re-
inforced concrete warehouse is to be
built near the site of the old shop A
track will serve both the warehouse
and shop jointly.
Blake Crusher Used.
"In order to handle the crushing OF
|coarse material such as lime rocks
matte and crude ore, a coarse crush
ing. or primary crushing plant mas
been completed adjoining the sample
mill. This plant is equipped with al
1sx3OAinch Blake crusher, bucket e'e
yators a sampler and screen.
"slow delivery of freight and ma
terial for the enlargement of tn
smelter has caused considerable de
law but it is expected greater spee'
