MILL LINERS
Bradken is a leading supplier of high quality
Mill Liner Systems to suit AG/SAG, Ball and
Rod Mills. By utilising the latest technologies,
we aim to provide customers with an
advanced Mill Liner System that increases
mill performance and availability.
The optimised design of Bradken’s range of
Liner Systems offers a number of advantages
including a reduced number of parts, fewer
relines, quicker change out and assembly
and safer handling ultimately resulting in
a reduction to overall
maintenance costs.
SUPER LINERSBy increasing the area of each head liner and reducing the number
of components Bradken Super Liners provide increased operator
safety and minimised mill downtime by making liner change-outs a
faster and safer process.
VORTEX AND SUPER VORTEX Bradken Vortex Discharge End has been developed to encourage
early discharge of coarse product that travels down the pulp lifters
during each revolution. The Vortex improves product movement and
decreases the time to exit the discharge cone, reducing pulp lifter
wear and improving pulp discharge from the mill.
PEENING PAD OPTIONSReduces metal flow around grate slots, preventing them from
closing up and maintaining mill throughput levels.
COMBINED CORNER LINERSImproves safety due to fewer loose liners.
FEED END COMPOSITE LINERSWhite iron inserts encourage consistent wear on feed end liners
to match shut down cycles. This can extend the life of liners and
reduce the number of relines per year and ultimately minimise mill
downtime.
BULLNOSE INSTALLATION BENEFITSBradken Bullnose Discharge Cones are manufactured from superior
wear materials to extend wear life and maximise mill availability. The
Bullnose Discharge Cone is designed with a key system to ensure
the last discharge cone installed fits with ease and requires no
mating parts to be removed.

Bradken Bullnose® Discharge Cones are designed and manufactured from rubber and metal components
specifically for Mill Liner applications incorporating a design focused on ensuring the discharge cone
assembly can be installed in the most safe and efficient manner, whilst extending the life cycle and
producing maximum tonnes.
Bullnose Discharge Cones can be customised to suit your specific application and operating conditions
and by utilising the latest 3D CAD (Computer Aided Design) modelling software, Bradken is able to
ensure Discharge Cone efficiency.
Bullnose Discharge Cones are manufactured from superior composite wear materials to extend wear life
of the liners, reduce weight and maximise mill availability. Each discharge cone design is tailor-made to
ensure safe handling, ease of installation and maximum performance.
Cast Lifting Lugs increase safety and allow for full
reline machine adaptability
Material selection and composition enables
extended wear life and weight reductions
The full cast white-iron nose and vanes maximise wear life
Unique Key system allows the Bullnose to be installed
independently of all other parts in the mill

The number of parts in your current assembly can be halved when
replaced with a Bullnose system
The Vortex® Discharge End has been developed to encourage early discharge of coarse product that travels
down the pulp lifters during each revolution of the mill. Vortex is proven to improve product movement and
decreases the time to exit the discharge cone, reducing pulp lifter wear.
Bradken Vortex Discharge Ends are designed to improve uni-directional AG/SAG mill performance. Each
design is customised to suit your mill size, application and operating conditions.
The Vortex design can be fully retrofitted into an existing mill or supplied for new mills.
The Bradken Vortex Discharge System:
• Provides superior discharge performance for SAG and AG mills
• Is ideally suited to high throughput, high solids discharge mills
• Increases ore throughputs, and
• Increases pulp lifter wear life.

COMPETITORBRADKEN
The Discharge End (DE) pulp lifter is a critical component of autogenous (AG) and semi-autog-
enous (SAG) grinding mills, having a significant impact on the throughput, efficiency and perfor-
mance of mills. Underestimating the importance of an optimised liner design in a mill can lead to
back-flow and carry-over processes which can ultimately result in high wear, poor liner life and
reduced mill throughput.
Installing a Bradken Vortex Discharge End and optimised liner design can lead to significant im-
provements in mill performance including:
• increased hourly mill throughput
• increased average mill throughput (fresh feed), and
• increased average re-cycle load.
CRUSHER LINERS
Bradken is renowned for providing world class quality and service to the mining and quarrying industries,
with our products specifically designed and manufactured to meet the increasingly demanding harshness
of these industries.
The optimised design of Bradken Crusher Liners for Gyratory, Cone and Jaw Crushers ensures an
uncompromising, reliable system delivering maximum performance and longer wear life. Bradken Crusher
Liners have been engineered with increased durability and strength to provide Bradken’s global customers
with a consistently higher level of productivity.
