Ball Mill Magnetic Lining Board

Magnetic lining board uses magnetic components to kind a curved open magnetic technique, and relying on the robust magnetic field to absorb the broken steel balls as well as the magnetic minerals in an effort to type a 20-30mm protective layer, thus decreasing the direct abrasion in the magnetic lining board and extending its service life. Compared together with the lining board produced of higher manganese steel, if adopted magnetic lining board, ball mill has higher ore grinding efficiency and decrease power consumption, for this reason, it can be a perfect replacement for higher manganese lining board.

The structure with the magnetic lining board is divided into two forms: one particular is relying around the magnetic force on the electric magnet to shield the original lining board; the other one is relying around the magnetic material to create magnetic lining board so that you can kind a automatic and renewable dynamic protective layer around the internal wall with the cylinder, which has been successfully applied in lots of ball mills.

The improvement course of the magnetic lining board in foreign nations: Within the 1970s, the researchers from the United states and Norway proposed the idea of making use of magnetic lining board to safeguard the ball mill cylinder as well as the chute. Within the 1980s, Swedish men and women place up with eight practical magnetic lining board structures. In the earlier stage from the 1990s, in some countries and regions which include Canada, USA, South continent and Africa, the magnetic lining board was widely used.

The improvement history of the domestic magnetic lining board: The research and improvement on the magnetic lining board in our nation began in the late 1980s plus the analysis institutes are Beijing Mining and Metallurgy Study Center, Shenyang Guangda Science and Technology Investigation Institution, Changsha Mining and Metallurgy Analysis Institute and Anshan Mining Designing Institute. Among them, the magnetic lining board researched and manufactured by Beijing Mining and Metallurgy Study Center was fairly mature; for instance, the HM entire set magnetic lining board applied in ball mill with the Balshan Iron and Steel Plant is a huge breakthrough within the application in the magnetic lining board. This sort of lining board is just not only the biggest ball mill magnetic lining board, but signifies that domestic magnetic lining board firstly realizes extensive magnetism with the substantial grinder lining board. Even so, the magnetic lining board researched by other study institutes can only be applied in the cylinder with the grinding mill and be restricted inside the medium and small-sized secondary ball mill whose diameter is under three.2m.

Together with the continual development of science and technologies as well as the investigation of far more advanced technologies, the structure and function of the magnetic lining board will come to be a lot more mature, and its application will come to be wider and wider in order that it'll bring much more economic positive aspects for the ore beneficiation plants.
