The Alcan Gove refinery installed three new rod mills, two mills online with an additional mill on stand-by, to meet 3.84 million tonnes per annum (Mtpa) Alumina. In the Definitive Feasibility Study (DFS), Alcan Engineering Pty Ltd had analyzed the existing 2-compartment rod/ball mills using the Alcan Comminution Package program at the Gove site.
The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.
