Vibrator for producing carbon electrodes - for the aluminium industry

摘要

The vibrator comprises a vibrating table, and a moulding box with a over weight which has a device producing additional pressure. The device is supported near the upper side of the box by a frame or a firmly fixed hood. Between the wt. and the frame or hood there is at least one pressure chamber in the form of a fluted sheel whose walls expand only in the direction of vibrations and yield to transverse movement of the wt. A liquid or gaseous pressure supply pipe opens into the chamber.
