The CTGG series wet drum magnetic separator is a heavy-duty permanent magnetic pulley-type separator designed for large-scale iron ore beneficiation operations processing hematite and magnetite ores. Built to deliver the high throughput capacities required by world-class iron ore producers such as Vale in Brazil's Carajas and Iron Quadrangle mining districts, the CTGG series accepts feed sizes up to 300 millimeters with processing capacities reaching 600 tons per hour. The robust mechanical structure with high-strength alloy steel drum shell and oversized bearings ensures reliable continuous operation in the demanding tropical mining environment of northern Brazil, where high humidity, heavy seasonal rainfall, and abrasive ore characteristics challenge equipment durability. The permanent magnetic circuit eliminates electrical power consumption for magnetic field generation while maintaining full separation intensity throughout the equipment service life.

• Exceptional Throughput Capacity: The CTGG design accepts large feed particle sizes up to 300 millimeters without pre-classification, enabling direct processing of primary crusher discharge or run-of-mine ore. Processing capacities from 100 to 600 tons per hour match the massive throughput requirements of Brazilian iron ore operations producing over 100 million tons annually.
• Tropical Climate Durability: The drum shell is fabricated from thick-wall stainless steel with multi-layer anti-corrosion coating rated for continuous exposure to the hot, humid conditions of the Amazon and Cerrado mining regions. All exposed steel structures receive heavy-duty epoxy primer and polyurethane topcoat systems providing over 15 years of corrosion protection.
• Energy-Efficient Permanent Magnet System: The magnetic circuit employs high-coercivity ferrite permanent magnets arranged in an optimized pole configuration generating surface field intensity of 300 to 500 millitesla. Zero electrical power is required for magnetic field generation, and the permanent magnet assembly retains full strength indefinitely without the heat generation, cooling requirements, or efficiency losses of electromagnetic separators.
• High Mechanical Reliability: The drum support structure uses self-aligning spherical roller bearings sized for 100,000-hour L10 design life under full load conditions. The belt drive system features heavy-duty pulleys with vulcanized rubber lagging for positive traction in wet conditions, reducing maintenance requirements at remote mine sites.
• Versatile Process Integration: The magnetic pulley configuration allows flexible installation as a head pulley on existing conveyor belts or as a standalone unit with dedicated belt feeder. The separator can be integrated into both dry and wet processing circuits, handling ore moisture contents from bone-dry to saturated without performance degradation.
• Low Total Cost of Ownership: Combining zero energy consumption for the magnetic circuit, minimal wear component replacement frequency, and straightforward maintenance procedures, the CTGG series delivers industry-leading operating cost per ton of ore processed for large-scale iron ore beneficiation operations.

The CTGG magnetic separator is the primary magnetic concentration equipment in iron ore beneficiation plants processing magnetite, titanomagnetite, and hematite ores throughout Brazil, Australia, and West Africa. In the Brazilian Iron Quadrangle and Carajas mining complexes, these separators process hundreds of millions of tons annually, recovering magnetic iron minerals from non-magnetic gangue to produce high-grade iron ore concentrates in the 65 to 68 percent Fe range. The equipment also serves in heavy media recovery circuits for coal preparation and dense medium separation plants, recovering magnetite media for recirculation. In gold processing operations, CTGG separators remove magnetic grinding media fragments from cyclone underflow streams before gravity concentration, protecting downstream centrifugal concentrators and shaking tables from magnetic iron contamination that compromises separation efficiency.

Each magnetic separator is factory-tested for magnetic field distribution, drum balance, and bearing alignment before shipment. The complete assembly is packed in reinforced wooden crates with VCI anti-corrosion protection and desiccant packs for maritime container transport to Brazilian ports including Vitoria, Rio de Janeiro, and Itaqui. Installation and maintenance manuals are provided in English and Portuguese. We offer 12-month warranty on all components, with extended warranty programs available for multi-unit orders. Technical support including installation supervision, commissioning assistance, and operator training can be provided at the mine site through our Brazilian service partner network.
