COMMINUTION
The company says that besides a strong
commitment to service and convenient access to
wear parts, the Patriot “will be recognised for
rugged structural integrity and high-grade
components to extend service life.” Internally,
bronze sleeve bearings are used for all moving
components that are load bearing or perform
load transmission (including countershaft
bushings, thrust bearings, head and eccentric
bushings and socket liners). In addition, these
critical components are cast of high-grade steel,
“which typically exceeds standards for
conventional cone crushers.”
Superior says engineers uniquely designed
high throw and high-pivot point crushing
performance to achieve strong production rates
at a low cost per tonne. Mobile applications will
appreciate a readily mounted design for
transportation on a cone/screen chassis.
For protection from costly structural damage,
each crusher is equipped with fail-safe hydraulics
to defend the unit against damaging mechanical

The crusher is driven
directly via a flexible
coupling to the electric
drive motor. This
arrangement eliminates
the need for sheaves and
v-belts, allowing for
simplified operation and
maintenance. A variable
speed drive package can
be included to optimise
the speed of the machine
to the given liner profile,
feed and production
conditions.
The lock bolt design for
holding the cone liner in
place eliminates the need
for a torch or burning ring.
In the event of tramp
material entering the
crusher, the hydraulic cylinder allows the release
of the material.

models include units for 150 to 375 kW

overload. Additionally, standard relief valves
within the dual acting tramp release cylinders
provide immediate, alternative protection should
the accumulator fail. Engineers also developed
overload sensing technology. In the event of force
overload, a simple alarm can activate or optional
advanced sensing technology will automatically
take the necessary corrective action. This same
automation can control the feed rate to optimise
performance, adjust other settings and monitor
critical lubrication and hydraulic parameters.
