ON THE COVER
Featuring advanced open table
designs, multi-port rotors and a larger
bearing capacity than most other VSI
crushers in the industry, the Trio VSI
crusher is capable of achieving high
throughput while offering reliable and
cost-efficient performance.
The large receiving hopper facilitates
easier feed conveyor placement while
the adjustable feed diverter ensures even
feed distribution into the crusher. An
important feature is the externally adjust-
able feed tube which allows adjustment
without opening the crusher. The conve-
nient inspection door mounted in the lid
allows safe and easy inspection.
Sukdhoe says that the Trio VSI crusher
is available with three different inter-
changeable chamber configurations.
“This allows for maximum application
flexibility and the Trio VSI crushers have
consistently demonstrated their ability to
produce high-quality cubical aggregates,”
he says.
Steel-on-steel configurations are suit-
able for crushing non-abrasive materials
in secondary and tertiary crushing appli-
cations with larger feed sizes, while a
rock-on-rock configuration is best where
additional fines or shape of material are
required. Rock-on-steel configurations are
used for crushing low abrasive materials
where a higher rotor speed is necessary to
achieve additional fines production.
Fully customisable to meet individual
operation requirements, the crushers can
operate in either open or closed circuits,
dependent on the type of performance
required.
An independent modular oil lubri-
cation system with built-in heating and
cooling ensures optimum bearing lubri-
cation. A flowmeter and temperature sen-
sors with interlock safety shut switches
provides protection for the bearings.
An integral vibration protection sys-
tem that includes a maintenance alarm
alerts personnel to potential problems.
In the event that excess vibration occurs,
the vibration switch will shut down
the crusher to protect it from possible
damage.
A further safety feature is the micro
switch incorporated into the lid lift. This
prevents the crusher from starting up
during inspection or maintenance.
Weir Minerals is known for its design,
engineering and manufacturing capa-
bilities, and Singleton says this plays an
important role in ensuring the crushing
machines provide reliable performance
while reducing overall cost of ownership.
“By partnering with customers from
design through to final decommission-
ing, our skilled personnel are able to
devise the best crushing solution to meet
customer requirements including the
production of a quality product for the
quarry owner,” Singleton concludes.
