dry magnetic separator

Material form and process compatibility, dry powder treatment: preferred to choose dry magnetic separation or electromagnetic iron remover, to avoid wet moisture introduction (such as graphite). Surry treatment: wet magnetic separation is more suitable for the continuous production of negative paste (such as silicon premixing stage). Impurity particle size and magnetic field strength, graphite iron chip is mostly micron scale, need 15,000GS magnetic field; iron oxide of silicon based material may be nanoscale, need 25,000GS high gradient PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.

PTMS Electromagnetic Separator

Natural graphite and artificial graphite particles are uniform and stable in structure, but the raw material may be mixed with ferromagnetic impurities (such as iron debris caused by mechanical wear). Iron removal requirements: PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Efficient removal of micron-scale iron impurities, to avoid affecting the electrical conductivity and cycle life.

what is magnetic separation process？

Silicon carbon composite and silicon oxygen composite, high specific capacity but easy particle agglomeration, and iron oxide may be introduced in the preparation of raw materials. Iron removal requirements: PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process nanoscale iron particles while avoiding damaging the composite structure. Lithium titanate spinel's structure is stable, but it is sensitive to magnetic impurities, so iron should be strictly removed to ensure safety.
