Technical Characteristics
-
The magnetic field is high, the magnetic field is up to 15000GS-30000GS, the magnetic field is evenly distributed, the gradient is high, and the iron removal effect is obvious.
-
Automatic operation, no manual operation, iron removal is convenient, thorough, no residue.
-
The magnetic system is characterized by large envelope Angle, multiple magnetic poles, and the absolute pair value of magnetic flux density in the separation area is relatively average, which can give full play to the sorting function of the magnetic system.
-
The 180 degree high temperature electromagnetic wire is 5-10 times more durable than the previous 130 degree electromagnetic wire.
-
Using forced water cooling mode, the excitation coil heat dissipation is fast, the temperature rise is low, and the magnetic field thermal attenuation is small.
-
The brake valve adopts imported material, the valve body is strong and durable, the switch is smooth, and there is no residual slurry overflow after closing.
-
The iron removal is washed by vibration and high pressure water pump, which is completely clean without residue.
-
Magnetic mesh is made of special material. After cutting off the excitation coil power supply, there is no remanence and it is easy to remove iron.

Frequently Asked Questions
What is the maximum magnetic field strength of this separator?
The magnetic field strength is exceptionally high, reaching up to 15,000 GS to 30,000 GS. The magnetic field is evenly distributed with a high gradient to ensure an outstanding iron removal effect.
What types of materials are suitable for this equipment?
It is designed for fine or powdered non-metallic minerals (such as feldspar, quartz, kaolin, frit, pigment, battery powder) and fine-grained mineral particles (including hematite, limonite, wolframite, and monazite) with a concentration of ≤30% and iron content ≤1%.
How does the cooling system work?
The machine utilizes a forced water cooling mode. This allows the excitation coil to dissipate heat rapidly, resulting in a low temperature rise and minimal thermal attenuation of the magnetic field.
Is the iron removal process automated or manual?
The system features fully automatic operation, requiring no manual intervention. The iron removal process is thorough, convenient, and leaves no residue.
What are the electrical power requirements for installation?
The standard input voltage required for the system is a 380V 50HZ three-phase four-wire electrical system.
Why is the electromagnetic wire more durable than standard wires?
This equipment uses a 180-degree high-temperature electromagnetic wire, which is 5 to 10 times more durable and heat-resistant than the standard 130-degree electromagnetic wires used in conventional separators.
