Stimir Installs Automatic Stub Protection Systems at Aluminium Plants

Automatic anode stub protection systems from Stimir of Iceland are an accepted technology in the primary aluminium industry. Recent installations include Nordic Aluminium (Iceland), Soeral (Norway) and Isal (Iceland).

Stímir's collar forming machine is a fully automated collar forming and locking system. With a small footprint and fast throughput the machine readily fits into existing rodding plants. The machine can handle both card and aluminium, which is loaded as a coil and automatically fed, cut to length, formed into a collar around the rod stub and securely closed with a punched locking imprint

The collar filling machine from Stimir uses a novel technology to accurately measure and dispense carbon paste into the card or alu-coil collars, fully automating this task. Prior to filling, the collars are automatically centered. The dispensing system ensures accurate and even distribution of the carbon paste, providing a virtually dust-free operation without spillage. This precision machine produces uniformly shaped and centered carbon collars.

Together, the Stimir Collar Forming Machine and Collar Filling Machine comprise an integrated Stub Protection System facilitating maximum anode shift life without unwanted anode stub erosion.

Stimir hf. is a solution provider to the primary aluminium industry, with particular focus on the Rodding Plant. All aspects of design and fabrication are undertaken at Stimir’s own facilities, ensuring total quality control and on-time delivery.
