➢Theycaneffectivelyextractandpurifyminerals
suchasmagnetite,ferrosilicon,hematite,
ilmenite,andotherstronglymagneticmaterials.

24. Continuous Operation:
➢Wet drum magnetic separators are designed
for continuous operation, ensuring a constant
flow of materials through the separator.
➢This feature leads to uninterrupted processing
and reduced downtime, resulting in higher
productivity and cost-effectiveness.

25. Adjustable Parameters:
➢Operators can adjust the magnetic intensity to
suit specific requirements of the materials being
processed.
➢This flexibility allows for tailoring the separation
process to achieve optimal results, even when
dealing with varying feed characteristics.

26. Low Maintenance:
➢Withfewermovingparts,wetdrummagnetic
separatorsgenerallyrequirelessmaintenance,
