Transcript:
The Corporation has a very complete generating station on the 'Work', from
which electrical current is distributed for the driving motors on various part
of the plant. In addition, a large block of power is obtained from the Railway
Commissioners' power hou se, at Zara Street, Newcastle. The current is
brought out from Newcastle at 33,000 volts and transformed down to 415 volts,
and this is used for supplying the cement plant.
The installation of a modern Portland Cement Plant at Cockle Creek marks
the latest of the Corporation's activities. After careful consideration of the
methods of manufacture now practised, the Corporation decided to adopt what
is known as the "wet" process.
A large plant, replete with all modern appliances, was installed by Edgar
Alien & Co., of Sheffield, England, at an expenditure of nearly a quarter of a
million pounds, and in 1925 a start was made with the manufacture of Portland
Cement by this wet, slurry process.
The present plant comprises one unit, with a capacity of 30,000 tons per
annum. The plant, however, has been designed for three units, and already
a start has been made with the erection of the second unit. This is practically
a duplicate of the first unit, but further modernised by the introduction
of a new Atomiser system for feeding slurry to the kiln. It is expected that
this second unit will be completed by the end of 1926.
The limestone (which is the principal raw material) comes from the
Corporation's extensive quarries at Attunga, and is of exceptional purity. The
clay and shale are drawn from the Corporation's land at Cockle Creek, and the
necessary coal is within easy reach of the Works.
As Cockle Creek the men are catered for as regards food by an up-to-date
canteen on the Works. This is controlled by the men themselves, and meals are
supplied at cost. There are also up-to-date change houses, with hot and cold
showers, and an ambulance room.
At the present time the men engaged at Cockle Creek and Attunga total 500;
besides which a large number of men are employed indirectly in other avenues,
such as loading and unloading of zinc concentrates, phosphate rock, sulphur, and
cemen t at wharves; and in th supply of stores, coal, etc.
BLENDE ROASTING PLANT.
Broken Hill concentrates represent a valuable source of sulphur for the
vitriol maker, and to this end a battery of six furnaces has been installed at
Cockle Creek.
The furnaces are of the Electrolytic Zinc Barrier Roasting type, of a design
that originated in Belgium, but which has been considerably modified by the
metallurgists of Australia. Each furnace consists of six hearths and a cover
arch. Alternate hearths revolve, and rabbling; is effected by teeth set in sockets
forming part of the hearth above.
The zinc concentrates (the moisture content of which is about 3 per cent.)
are fed by a screw on to the top hearth and worked down through the furnace,
and finally discharged into a conveyor for disposal on the calcines stock pile.
No outside fuel is used, but the ore once started can be kept burning by a
careful regulation of the draught, which is supplied by steel fans.
The furnace gases, carrying about 5.5 per cent· SQ 2' are delivered to the
chamber plants through steel or cast iron flues.
