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 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.

The main characteristics is a superior wear resistance: Severe wear on the surface has a work-hardening effect on the austenitic structure of this steel. This, when combined with the level of carbon in accordance with the international standards, leads to an increase in hardness from 200BHN (in as delivered plates) up to an in-service hardness of at least 600BHN. Typical Applications: · Quarries and Constructions: Earth moving crusher jaw, grizzly, screen, stone chutes, chain guide and shredder plates, shovel buckets. · Mines: Bucket blade of loader, chain conveyor parts, sprocket wheel, various armouring elements. · Iron Industry, Foundry: Guiding and shifting plates, scraps container, liner of shot blasting unit, pedestal liner, flanged bolster cup, wear liner. · Concrete and Brickworks: Core and dividing wall of parpen mould, grinding mill scraper, mixer paddle. · Scraps â?? Recoveries: Wheel disk, striker and hammer mill. · Automotive Industries: Shot blasting equipment. It is also used for its low coefficient of friction in metal-to-metal applications, its non-magnetic properties in electrical transformer assemblies and for industrial lifting magnets. A high manganese, fully austenitic, quench annealed, non magnetic, work-hardening steel with an exceptionally high level of wear resistance when subjected to work-hardening by shock or high impact pressure in service. The main characteristics is a superior wear resistance: Severe wear on the surface has a work-hardening effect on the austenitic structure of this steel. This, when combined with the level of carbon in accordance with the international standards, leads to an increase in hardness from 200BHN (in as delivered plate) up to an in-service hardness of at least 600BHN. This work-hardening capability renews itself through out in-service life.The underlayers not work-hardened maintain an excellent resistance to shock and a very high ductility.
