The working principle and characteristics:
Conventional ball mill liners mainly affected by the impact, grinding force and electrochemical corrosion and wear, magnetic materials and magnetic lining N, S poles are alternately arranged to form a curved open magnetic system, with the strong magnetic adsorption broken ball, 20-30mm magnetic minerals forming the protective layer, greatly reducing the wear of the magnetic liner directly improve the liner life. Although magnetic liner one-time investment is large, but far below the average annual consumption of manganese steel liner, liner costs 7-9 million annual savings, long life, low cost, light weight, easy disassembly and save 6% -7% of electricity, saving the ball 1% -2%, increasing the volume and increase the amount of ore to further improve grinding efficiency, improved mill operating rate of 1% to 5%. Through ten years of industry operating statistics show that the magnetic liner is manganese steel liner replacements.
Scope:
1, Widely used in all kinds of magnetic minerals
Magnetic minerals comprising: a ferromagnetic minerals, magnetite, hematite, etc.; moderate magnetic minerals, ilmenite, hematite illusion; weakly magnetic minerals, most iron manganese ore, hematite.
2, Widely used in the non-magnetic minerals
In recent years, we actively developed grinding non-magnetic minerals, such as copper, gold, lead, zinc, etc., and have made a breakthrough, according to user requirements and design, production, installation, commissioning, to meet the needs of customers, the study practice has proved that the magnetic liner widely used around Φ60 ball, and it would be best to use a baseball, the better. For more than Φ70 ball, they have each plant according to the nature of the ore feed size and other conditions to develop the design, production and installation work
Installation and Precautions:
When installed, the magnetic cylinder liner along the inner wall surrounding the mill was N, S poles alternately arranged, the use of magnetic force in the tube wall without bolts, watertight, missed mine, when the initial installation is best to manually add the chopped ball , broken iron or iron
