<p>An insulator (10) for an alumina point feeder (12), the insulator (10) comprising an annular ring (15) of a refractory material. The ring (15) being defined by first and second generally semi-annular portions (14, 16). The annular ring (15) has a radially inner region (18) locatable adjacent to a generally cylindrical portion of the point feeder (12), and a radially outer region (19). The insulator (10) also comprises a band (30) extending circumferentially around the radially outer region (19). The band (30) secures the first and second generally semi-annular portions (14, 16) to each other.</p> |
