In the production of fine chemicals or high-purity quartz sand, raw materials contain extremely low iron impurities but require exceptionally high purity. This makes high-gradient permanent magnet PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC or tubular PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC systems more suitable, as their precise magnetic field gradients can effectively capture micron-level iron particles. Material particle size also plays a critical role: coarser particles with stronger penetration force demand more intense magnetic fields for effective adsorption.
Fine powder materials are easily carried away by airflow, requiring the use of sealed iron removal devices to prevent dispersion. In practice, a silicon material company initially failed to adequately assess raw material properties and mistakenly selected conventional suspended permanent magnet PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC systems. This resulted in ineffective removal of nano-scale iron oxides, ultimately causing non-compliant product resistivity levels and frequent customer complaints.
After process diagnosis, the company switched to a multi-stage high-gradient PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC system combined with airflow classification pretreatment, which significantly improved iron removal accuracy. This demonstrates that scientifically evaluating material characteristics and selecting appropriate iron remover types, specifications, and installation methods based on these assessments are prerequisites for achieving precise iron removal.
