KX Co-Kneaders

The aluminium specialist

High-end mixing and kneading technology for anode paste production in the aluminium industry.

For more than 70 years, BUSS Co-Kneaders have been the benchmark for cost-effective compounding of anode paste in the aluminium industry. We continue the tradition with our current KX series. Safe. Efficient. Proven.

This technology ensures consistently high and uniform quality anode paste at high specific output.

The advanced KX geometry provides the following main advantages:

  • Throughput/performance for current and future requirements in the aluminium industry
  • Optimal mixing and pitch dispersion without clumping and deposits
  • Reduced pitch consumption due to highly efficient mixing
  • Longevity and stability for low operating and maintenance costs

KX Co-Kneaders

The unique operating principle

The KX Co-Kneader process zone is divided into four functional sections, in which the screw geometry is optimised for the specific task:

Intake section
Intake section
The intake section takes up the incoming coke and transports it into the process zone by feeding elements with continuous flights.
Transition section
Transition section
In the transition section, liquid pitch is directly injected into the feedstock via drilled kneading bolts. At the end of this section, the screw profile changes from transport to mixing and kneading.
Kneading section
Kneading section
In the kneading and mixing section, the focus is on optimum mixing. Innumerable flow separations and reorientations with uniform shear rates ensure maximum homogeneity.
Dynamic throttling
Dynamic throttling
Dynamic throttling is an innovative feature that replaces the flap-die used previously. Screw flights with reduced feeding effect slow down the mass flow to increase the filling degree in the kneading section, resulting in optimized mixing.

Properties & benefits

Unique features of the KX Co-Kneader

  • Improved and uniform anode quality thanks to optimised mixing technology, dynamic throttling and an adjustable flap gate

  • Higher specific output per machine size

  • Improved accessibility due to elimination of the external shaft bearing and heating

  • Less maintenance effort thanks to low wear

  • Lower investment, installation and maintenance costs thanks to electrical heating and elimination of hydraulic systems

  • Electrical heating for greater safety and ease of use

  • Optimal mixing and pitch distribution by injecting liquid pitch, simultaneous prevention of buildup and clumping

  • No volatile emissions or caking on the shaft thanks to liquid pitch injection

  • Optimally reduced pitch consumption thanks to highly efficient mixing

  • Greater operator and plant safety

  • Shorter downtimes and improved serviceability

  • Robust and stable machine design

  • Longevity and stability for low operating costs
