Stimir of Iceland has shipped an anode butt stripper and a thimble press to Russian Aluminium.
Both machines will be installed at Rusal’s Sayanogorsk smelter as part of a development process line in the rodding plant.
Stimir’s manual butt press is a compact scissor-type spreader designed to work between the yoke and the top of the anode butt. The unit is designed to remove the butt in one operation.
The butt press is suspended by a chain and is manually positioned between the yoke and butt. Operation is by hydraulic lever-valves located on the handle of the equipment. The unit is able to exert up to 15 tonnes of dynamic force to remove the butt from the yoke assembly and is capable of stripping butts from two different designs of yoke.
Stimir’s thimble press is an hydraulically powered compact unit and is able to exert up to 200 tonnes of dynamic force to remove single thimbles from the yoke assembly.
The rod assembly is suspended from the overhead conveyor and stub in turn is guided into the press. For this installation operation is by manual pushbutton but the design is readily converted to fully automatic operation. The unit is capable of stripping thimbles from two different designs of yoke.
