Range of application: 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
