The Magnetic liner is new generation liner which are used in the ball mill with stable performance and reliable quality. The Magnetic liner produced by shengnuo group can be widely used in ball mill fromΦ1500 to Φ3600. The material of metal shell is non-magnetic hard alloy steel with wear-resistance, acid- resistance, alkali-resistance, corrosion-resistance, high magnetic permeability. The strength and thickness layer on the metal shell could ensure the magnetic liner service life.
