Vibrerende kompaktor for fremstillingen av tilformede legemer ved sammenpressing

摘要

To create a vibrating compactor with mould (11), preloaded over weight (12) and firm cover hood (14) for compacting grainy raw materials by vibration for shaping especially anode blocks (16) for molten phase electrolysis for the production of aluminium the service life of the at least one cover weight pressure spring (18) of which shall not be impaired by the atmosphere within the system of mould (11)/cover hood (14), the invention suggests to have the cover weight preloading device with the at least one pressure spring (18) arranged outside the mould/cover hood (14).
