STAS, a Canadian manufacturing company well known for its wide range of casthouse and crucible shop equipment for the aluminum industry, has developed a new pot ramming machine used to compact the ramming paste during the pot lining process, with improved performance and innovative characteristics (Figure 1). As the machine is used in the vicinity of operators, the ergonomic aspect has been a primary design criterion. Visibility, noise, and vibration levels have been optimized to an unprecedented level for a vibrocompaction pot ramming machine, with a measured noise level well under 80 dB during operation. A patent pending compaction ram allows a very slim design next to the operators, while providing maximum visibility and offering a vibration decoupling function. This ram is also intended to move the compaction tool in a perfectly vertical trajectory, which will greatly facilitate the operation while ensuring more uniform compaction. Moreover, easy operation and optimized ramming are ensured by dynamically tuneable parameters.
