DEVELOPMENT
SITE FOR CEMENT
PLANT IS SELECTED
Will Manufacture Sand Ce-
ment to Be Used in Con
struction Of Big Dam.

Elephant Butte, \. NJ, Oct 10
Harry Stanton. one Of the Rio Grande
project engineers, has sta1ed the site
of the sand cement plant TO be erected
here. The location is little north
east Of the storage or finished product
building
This plant is made necessary by the
large quantities of concrete to be uSed
in The construction Of the dam
A cement made from certain bleno-
fngs of Portland cement with sand ana
ground sandstone from local quar-
ries produces a product known as
sand cement that experiments prove
TO be very imperviOus TO water ana
capabie Of resisting great pressure
VIII Replace Portland Cement
This sand cement, to be manuIac-
tured here, viii be used IN place OF
Portland cement in producing the
concrete for the dam.
The first unit of the plant TO pc
constructed is the tube mills and the
Taylor Engineering q ManuIacJuIlL6
company has the contract Tor 4hslall-
ing the machinery Tor the IuDe MINIS
Great preparations have already
been made for manufacturing and
handling the concrete. large Dullu-
ing. about 20 feet high from basement
to roof. has been constructed near the
site OF the dam 1t contains three
large mixers h0ppers, bins for SAND,
crushed stone and cement with al
necessary machinery operated by cleo
trical power
Two Large Crushers.
Close to this building are two large
stone crushers, with inclined bins,
lined with steel Rock drawn from
the quarry is dumped direct from the
cars into the bins and men stand be-
low to help feed the mills.
As the crushed rock comes from
the crushers, it falls into the buckets
and is carried by electrical power TO
the bins above the mixers Each OF
these cOnveyOTs has capacity OF 1OO
tons per hour.
on the east side of the building is
z sand elevator with a capacity OF
100 tons Of sand per hour. "A fourth
cOnveyOr connects the cement storage
building with the cement bins above
The mixers.
The conveyor is a wide rubber belt,
also operated by electrical power ana
has q. capacity Of 30 tons per hOur-
This cOnveyOr is housed IN a long IN
clined hall and there IS room WlInlu
for a man to walk on either side Of
the conveyOr and in this way one can
reach the top Of the building.
Machinery Perfectly Adjusted.
The machinery is so adjusted that
inst the right proportions of cement,
sand and crushed rock enter the mix
ers and water is at hand.
Each Of the three mixers has a ca
pacIty Of 1 II yards Of concrete per
J.
The concrete is transferred to the
desired location as follows. A track
runs under the mixer and the concrete
runs from the mixer into a skip rest
ing on a car. The skip has a capacity
of three yards. The car is drawn out
under the cable way by means Of a
stationary engine with ropes and pull
ley. This engine viii DO the Work
for all three mixers
The graphing hooks are attached to
the skip and it is hOisted and quickly
transferred across the river and after
being lowered is moved by one Of the
electrical derricks TO the required To-
cation
The plant is not quite complete, but
after the hydraulic sylinders are in
stalled the hoppers connected with the
machinery Of the mixers viii be Oper-
ated by levers and one man will be
able to operate each mixer.
Engineer Stanton has had the direct
superintendency of the construction of
this complicated plant.
