As of August 1, 2008 year Buss AG of Pratteln, Switzerland will be marketing its large CP Kneaders again. That is when a ten-year marketing agreement with Buss ChemTech AG in Pratteln ends. During this time Buss AG continued manufacturing the CP Kneader – used for anode paste compounding in electrolytic aluminium production – and improved it both from the mechanical and process technology points of view.
Buss AG was also responsible on behalf of our marketing partner for CP Kneader spares and replacements as well as local service. With CP Kneader marketing, manufacturing and service all in the hands of Buss AG as from August, anode paste processors can depend on unbroken continuity. All the leading aluminium producers worldwide use BUSS Kneaders today – currently at least 200 of them for anode paste processing.
It is now more than fifty years ago since Buss AG first developed a special-purpose Kneader family for aluminium production. These BUSS Kneaders are used for compounding calcinated petroleum coke with pitch into the high quality anode paste required for electrolysis. The first BUSS Kneader for anode paste processing was commissioned in 1951 at Aluminium Rheinfelden in Switzerland. Since then Buss AG has continuously developed and optimized the CP type Kneader family in step with production and process technology advances.
