MJT-DS Series High Gradient Magnetic Separator for Iron Removal - Top China Suppliers & Factory Equipment
Scope of application
For fine or powdered non-metallic feldspar, quartz, kaolin, frit, pigment, battery powder and other raw ore iron oxide (Fe2O3) or other weak magnetic impurities and mechanical iron mixed in the process of separation of magnetic substances; Remove weak magnetic oxides, dust rust and other pollutants from powdery materials, widely used in refractory materials, ceramics, glass and other non-metallic minerals and chemical, pharmaceutical, food and other industries purification materials; Sorting fine-grained mineral particles, such as magnetically fine-grained black metal hematite, pseudohematite, limonite, siderite, chromite, manganese ore, etc. Fine grade nonferrous metal wolframite, fine grain rare metal monazite and so on.
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
It is widely used in refractory materials, ceramics, glass, chemical, pharmaceutical, and food industries to purify materials. It is ideal for fine or powdered non-metallic minerals (like feldspar, quartz, kaolin, frit, pigment, battery powder) and sorting fine-grained mineral particles (such as hematite, limonite, siderite, chromite, manganese ore, and wolframite).
The equipment features a high, evenly distributed magnetic field with a high gradient, reaching induction intensities from 15,000 GS up to 30,000 GS, ensuring highly effective iron removal.
The separator utilizes a forced water cooling mode. This design ensures rapid heat dissipation from the excitation coil, keeping the temperature rise low and minimizing thermal attenuation of the magnetic field.
The adaptive materials should typically be nonmagnetic fine powders or granules (around 8 meshes), with a material concentration of ≤30% and an initial iron content of ≤1%.
Yes, the system features fully automatic operation with no manual labor required. The iron removal is washed using vibration and a high-pressure water pump, ensuring it is completely clean and leaves no residue.
The system uses a 180-degree high-temperature electromagnetic wire that is 5-10 times more durable than standard 130-degree wires. Additionally, the brake valve is constructed from imported, high-strength materials to ensure smooth switching and prevent slurry overflow.
