Advantages of magnetic liner: 1, Long Life 2, Save energy 3, Saving steel ball working principle: The advent of magnetic liner is a major contribution to the history of the mill liners, marking the arrival of a new era liner, began to bid farewell to manganese steel liner heavy stupid and short-lived history. After installation, the magnetic cushion liner surface ore crushed by the balls, steel sections and magnetic mineral composition of adsorbed on the surface of the liner formed by magnetic sine wave peak; After the operation, the iron, steel sections, broken balls, small balls and by grinding the material to form a hard protective layer of permanent. During operation, the upper protective layer has a thick layer of magnetic material and the current meson balls (section) composed of a magnetic material in the ore and the medium powder abraded, broken balls, pellets and other natural wear protection is formed continuously worn continuously generate supplement, always in a state of dynamic balance, the cycle of magnetic liner to protect the mother. The thickness of the protective layer formed on the surface of the magnetic liner is 20-30 mm, since the protective layer is firmly adsorbed on the surface of the magnetic pull the liner to prevent the medium and the magnetic material to be ground by direct impact of the liner strip mill. This greatly weakened by grinding media and wear directly on the lining material, greatly extending the life of the magnetic liner. Therefore, the country has been called magnetic liner "never worn" liner.
