VHE of Iceland has developed the Stimir robust rotary crusher. The unit is suitable for pre-crushing of large bath pieces.
At Alcan Iceland, and at Nordural also in Iceland, the Stimir bath crusher is used to process bath emptied from spent anode transport trays. Bath is crushed to 200-250mm and is discharged to join the main bath conveyor from the anode cleaning machines.
A similar crusher design is also available to pre-process large pieces of anode butt.
