KX Co-KneadersThe 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 Compounder Most efficient mixing technology for anode paste

Kneading Process – In the kneading and mixing section, the focus is on optimal mixing with gentle processing of the coke fraction. Numerous flow separations and deflections with consistent shear rates ensure maximum homogeneity. This leads to optimized performance of the anode end product. Robust Construction – The KX Kneader is designed for the highest application demands. Years of experience result in long service life, stable operation, high uptime, and reduced maintenance costs. Pitch Injection – In the transition area, liquid pitch is injected directly into the feed material through drilled kneading bolts. The design ensures optimal distribution and dosing of the pitch to optimize quality and operating costs. Electrical Heating – The process area is electrically heated. This concept avoids additional installation costs compared to liquid heating (HTM). The electrical heating, combined with the robust construction of the KX, allows for restarting with a fully loaded kneader barrel after longer, unplanned downtimes, thus contributing to low operating costs.

Das robuste Design des KX Ko-Kneters führt zu einer langen Lebensdauer des Compounders und zu einem reduzierten Wartungsaufwand. Die Injektion von flüssigem Pech über gebohrte Knetbolzen führt im Prozessraum zu einer optimierten Einmischung für maximale Qualität in der Compoundierung von Anodenmassen. Die elektische Beheizung des Prozessbereichs des KX Ko-Kneters ist effizienter als die Flüssigbeheizung (HTM).

KX Co-KneadersThe 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.
