Sandvik installs its first primary<br />
gyratory crusher<br />
Coal Insights Bureau<br />
Sandvik Mining and Construction, a<br />
unit of Sweden-based Sandvik Group,<br />
has installed its first primary gyratory<br />
crusher, a CG820, in a record time of only 18<br />
days, at the iron ore mine of Tata Steel Ltd at<br />
Noamundi, a company official said.<br />
“This is the quickest know time for<br />
replacement of an old crusher, including<br />
total installation of a new primary gyratory<br />
crusher,” the Regional Product Line Manager,<br />
Mine Crushing, Sandvik Asia, Avijit Paul,<br />
said.<br />
The 18 day-period of installation<br />
comprised dismantling the old crusher and<br />
two feeders, assembly and installation of the<br />
gyratory crusher, erection of apron feeders,<br />
installation of VFD drive and complete<br />
automation, Paul said.<br />
A replacement and installation of this size<br />
usually requires a minimum time of 30 days,<br />
he claimed.<br />
The crusher was supplied by Sandvik Mining and<br />
Construction for the processing of ore with a maximum feed<br />
size of 1200 mm (47.2 inches) and capacity up to 3500 mtps<br />
(3858 stph).<br />
The CG820 primary gyratory crusher replaced a Fuller<br />
Trailor primary gyratory crusher in the plant. The replacement<br />
will lead to modernisation of the primary crushing stage,<br />
increased capacity, large feed size intake and a more power<br />
drive, Paul said.<br />
According to him, Tata Steel chose Sandvik as supplier<br />
due to its ability to present a technically superior design with<br />
such features as spherical spider bearing,<br />
hydraulic adjustment, secured concave liners,<br />
hydraulic tank instrumentation system and<br />
the unique Automative Setting Regulation<br />
System.<br />
“In addition, delivery time was one of<br />
the key points in securing the order. The<br />
installation time was the shortest recorded<br />
at Tata Steel for a job of this magnitude,” he<br />
added.<br />
“The Sandvik CG820 primary gyratory<br />
crusher supply will be a reference point of<br />
major value, since it is the first crusher of this<br />
type to be supplied by Sandvik and has been<br />
supplied to the world-renowned company,”<br />
Paul said.<br />
Moreover, the overall job of dismantling,<br />
installation and commissioning was a success<br />
in terms of time, he added.<br />

with advanced products and world-leading<br />
