Section snippets Experimental data. In this paper, the wear evolution of a liner plate in the first chamber of an industrial m diameter cement ball mill, also known as a tube mill, with two chambers is studied on the basis of the experimental data provided by the company Magotteaux International The total length of the mill is equal to m, while the first chamber is only m long.
WhatsApp: +86 18203695377The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling. In this way an optimum compromise can be achieved between grinding efficiency and the equipment´s lifetime.
