Vortex Discharge End

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.

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.

Benefits of an optimised discharge end

The Bradken Vortex® Discharge End has been developed to encourage early discharge of coarse product that travels down the pulp lifters during each revolution.

The geometry of the Bradken Vortex® Discharge End not only improves pulp chamber efficiency by eliminating pulp back-flow but that efficiency is not compromised by the higher mill speeds required to maintain trajectories and breakage conditions inside the mill as shell liners wear.

The Bradken Vortex® Discharge End can be supplied for new mills as well as being retrofitted to mills that have originally been drilled to accommodate a radial design pulp lifter arrangement. Each design is customised to suit your mill size, application and operating conditions.

The Discharge End (DE) pulp lifter is a critical component of autogenous (AG) and semi-autogenous (SAG) grinding mills, having a significant impact on the throughput, efficiency and performance 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 improvements in mill performance including:

• increased hourly mill throughput

• increased average mill throughput (fresh feed)

• increased average re-cycle load
