Dry magnetic ring separators are dry, high-gradient, strong magnetic field separation devices. Their core functionality relies on magnetic force, vibration, and rotation to separate magnetic and non-magnetic materials.
Dry magnetic ring separators have evolved from early models characterized by low field strength, easy clogging, and low efficiency to a new generation of equipment featuring permanent magnetization, high-gradient strong field, vibration combined with intelligent control, wide particle size distribution, low energy consumption, and high adaptability. Key advancements include:
Permanent magnetization replacing electromagnetic systems: Moving from traditional electromagnetic systems (power-intensive, heat-generating, and maintenance-intensive) to using neodymium iron boron permanent magnets, resulting in high magnetic field strength, low demagnetization rate, no excitation required, and environmentally friendly and energy-saving performance.
High-gradient strong magnetic field: The magnetic field gradient is increased by 10-20 times, efficiently capturing weakly magnetic particles.
Magnetic reversal and agitation: Alternating magnetic poles and relative rotation generate high-frequency magnetic reversal, reducing inclusions, improving concentrate quality, and reducing tailings.
From easy clogging to smooth and efficient operation: The ring magnetic design solves the problems of dry material sticking and difficult unloading; fine particles do not agglomerate, resulting in more efficient separation.
From high-consumption to low-carbon dry processes: The entire process is dry with no water consumption, suitable for harsh environments with limited water resources. It is environmentally compliant, has a simplified process, and features efficient permanent magnet transmission with low energy consumption.
