GIRL TO |
START WORK
Construction Company's Rock
Crushing Plant Ready for
Operation Next Week. !

When Marguerite, the little
| daughter of j. j. Belser, losses the
first stone into the new gyratory
crusher of the Honolulu Construc-
tion Co.. at the Moiliili quarry early
next week, work will be started by
the biggest rock crushing plant ever
erected in Hawaii This rock crush
! ing plant called for a considerable
! investment on the part of the con-
struction company, and the starting
Of work is to be rather formal. Some
| thing in the way of celebration
! will proceed the event and TO bring
I future success to the work, the little
girl is to feed the first stone to the
crusher.
The plant is somewhat screened
! from the view of passengers on pass
ing Kaimuki Rapid Transit cars and
one Is impressed with the size of
the stru ture that houses the ma
chinery of this new industry. Many
men are employed about the quarry
i in getting out the stone for the gov
eminent crusher in the same quarry,
and many more are now at work
there for the Honolulu Construction
Company.
On entering the new building. a
better understanding of the promise
+ that the new plant can manufacture
900 cubic yards per day is gained.
Great fly wheels, immense boilers
and roch elevator that runs up
eighty feet, shows that this is no
plant for temporary work, but fac
nv, hDt y,ill CT MO far in
the future
The machinery used in the rock
and sand factory is the latest pro-
duet CT the McCully Curator Crush

of the machinery that brushes the
big boulders as they are thrown into

where it is separated by machinery,
never stopping in transit. the big
parts returning on the elevator and

On its return to lower elevation

first mentioned, and from here the
unbroken pieces go to the screening
machinery where it is automatically
separated until every portion is
ground to the size desired. A big
boulder placed in the mauling ma
chinery can be reduced to sand or
dust size within five minutes.
The crushed stone or sand is re-
moved from the bunkers by very
simple process Wagons will enter
a tunnel-like driveway at one side
CT the building arjl here bunker
gates directly overhead will be OPP
ened and gravity will carry the ma
terial into the wagons. Gravity
| seems TO be called upon to do all
| the arduous work of the factory, ex-
| cepting that of getting the stone out
I of the quarry After the machinery
gets the first hold on the rock. steam
and gravity will do the rest.
The engine room of the factory is
OF more than passing interest. There
are two boilers, of $50 horsepower
each, which are oil burners. The
feed and oil pumps are all in. >dupff-
cate. The engines and machinery
were put in under the direction OF
Chas. Simpson. an engineer who has
been employed on many big mechan-
ical jobs In Hawaii. J. Kennedy
had charge OF the erection of the
boilers.
There will be four kinds of the
crushed rock products of the Homo
lulu Constru tion Co. 1t is expect
ed that there will be a decided de-
mand for the sand product to take
the place Of beach sand which has
not sufficient strength for the con-
crete construction work, Sand from
this factory being made from the
hardest lava rock will make mater
ial that can not be duplicated for
concrete work.
