In non-metallic mineral processing, metallurgy, and chemical industries, efficiently treating weakly magnetic minerals below 5mm—such as hematite, limonite, ilmenite, chromite, and manganese ore—while solving the global problems of clogging and severe material carryover in conventional magnetic separators, has long been a technical challenge. Many users find that traditional permanent drum separators have limited effectiveness on weakly magnetic impurities, while high-gradient vertical ring separators, though powerful, are expensive and prone to clogging. The plate magnetic separator designed as a wet high intensity magnetic separator has changed this situation entirely. Combining the high-throughput capability of a plate structure with an ultra-high-intensity magnetic field, it offers an excellent, cost-effective solution for wet separation of weakly magnetic minerals.
How Does a Plate Wet High Intensity Magnetic Separator Work?
The core advantage of this plate magnetic separator lies in its unique design concept. The equipment consists of a support frame, a plate magnetic system, a feed agitation system, a water system, an iron discharge system, and an adjustment system. Its working principle uses a counter-current flow structure: non-magnetic material flows out by gravity and is thoroughly rinsed away, while weakly magnetic target minerals are captured by the ultra-high-intensity field over a long, multi-pass zone, then carried by the reverse-running discharge system to the iron outlet and rinsed off. This completes the precise separation within the wet high intensity magnetic separator.
Key Customer Concerns About the Plate Wet High Intensity Magnetic Separator
Separation Accuracy and Efficiency
Many weakly magnetic minerals (manganese, hematite, chromite) have very low susceptibility, making them difficult to capture with conventional equipment. This plate magnetic separator uses computer-simulated, opposed-pole magnetic circuits to maximize capture area and force. The magnetic core is made of high-strength rare earth Neodymium, achieving peak field strengths up to 18,000 Gauss. This ultra-high field efficiently captures weakly magnetic impurities that conventional equipment misses, significantly improving concentrate grade.
Clogging and Carryover
This wet high intensity magnetic separator fundamentally solves the clogging and carryover problems common with fine-particle processing. The smooth plate structure ensures unobstructed material flow, while the counter-current discharge system cleanly strips magnetic particles, preventing adhesion and simplifying cleaning.
Stability and Maintenance
The plate magnetic separator features a fully sealed design with excellent oxidation protection, ensuring less than 5% magnetic decay over ten years in harsh environments. The variable-speed drive enables fully automatic continuous operation and iron discharge, saving labor and ensuring reliable performance. All material-contact parts are stainless steel or non-magnetic materials, preventing secondary contamination. The equipment can be customized as open or fully sealed to suit site conditions.
Commissioning and Operation
To achieve optimal separation with this wet high intensity magnetic separator, proper commissioning is essential:
-
Level the unit using the magnetic plate as the reference.
-
Check belt tracking and adjust if necessary.
-
Maintain material bed thickness between 1-5mm based on feed density and particle size.
-
After shutdown, flush thoroughly with water to prevent belt adhesion to the magnetic plate.
Applications of the Plate Wet High Intensity Magnetic Separator
This plate magnetic separator is widely used for weakly magnetic minerals below 5mm and non-metallic mineral iron removal, including:
