Magnetic Liner For the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time. or the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time. But for the magnetic liner, the working principle is quite different: these magnetic liners are arranged alternately in the ball mill to form a strong magnetic field, the magnetic liner attracts a layer of broken or small steel balls and ferromagnetic minerals to the liner surface when in operation, thus forming a natural dynamic protective layer. In initial period, the workers can add broken balls or iron powder to help form the protective layer, which often can be 20~30mm. So the service life of the magnetic liner is extended greatly, is generally 10 times even dozens of times of high manganese steel liner. Material: Material and production process of the protective metal casing: Our company is researchers developed a special non-magnetic material, which consists of  military special alloy metal and some necessary elements. This type material has many great properties:such as wear-resistant, acid-proof, Alkali-resistant,corrosion resistance and excellent non-magnetic permeability. All these properties enable the formation of sufficient strength and thickness of protective layer . By using EPC casting process, we produce metal casing with neat appearance and precise size, so the contact surface of the cylinder and magnetic liner can up to more than 95%. Material of the magnetic Based on years of experience, our company always use the the magnetic material with stable performance and reliable quality,this ensures high quality of our products, and in some vulnerable parts we add some NdFeB magnetic materials. Material of the waterproof glue Our company use imported waterproof glue, the strong adhesive makes the magnets and the protective layer firmly bonded together. And the good water resistance propertity makes the waterproof layer on the magnet surface have sufficient strength, not destroyed in the transportation, installation and use. -

Magnetic liners are essential wear-resistant components installed inside ball mills in mining and mineral processing operations. Made from high-grade magnetic alloy steel, these liners protect mill shells from ore pulp impact and electrochemical corrosion during grinding cycles. Available in standard curved segment configurations compatible with common ball mill models, magnetic mill liners offer superior durability and reduced maintenance downtime. Widely sourced from steel-producing regions for export to mining operations worldwide, these liners are classified under standard machinery parts codes and typically shipped in bundled steel racks or containers for secure transport.
