The production process of artificial graphite is complex, and iron impurities may be introduced in several links. In the process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal screening, the iron removal sieve is relatively easy because the artificial graphite particles are relatively regular and the structure is relatively stable after granulation and graphitization. However, if the iron impurities in the particles are wrapped in the granulation process, it is necessary to use a strong means of iron removal, such as magnetic separation machine.
Moreover, the electrical conductivity of artificial graphite is good, in the use of electromagnetic PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC equipment, may be subject to electromagnetic interference, need to pay attention to the shielding of the equipment. Natural graphite has a layered structure, in which iron impurities may be adsorbed between layers or embedded. In terms of iron removal sieve, the iron removal methods that can go deep into the interlayer structure are needed, and the magnetic separator has certain advantages in this respect.
However, the purity of natural graphite is relatively low, and the initial iron impurity content may be high, requiring more stringent PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron sieve removal operations. At the same time, the particle size of natural graphite is not uniform, in the screening process, we need to choose the appropriate screen aperture, to ensure that the graphite of different particle size can be effectively removed from the iron sieve.
