The Dry Magnetic Separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, limonite, and tantalum-niobium, etc. Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water.
Dry magnetic separator working principle:
Mineral sorting through the vibrating feeder evenly separate of the upper tube, rotate the cylinder to cylinder behind that of non-magnetic materials, magnetic materials by the strong magnetic field force suction to the cylinder, with sub-ore easily board,accurate to the magnetic separation of non-magnetic materials. Strong magneticfield strength with Drum Magnetic separator for sub-select, weak magnetic minerals into a reality. Equipment to deal with a large amount of sorting awide range of mineral grain size, separation of high precision, non-blocking;simple structure, easy maintenance, strong electro magnetic power consumption of only 20% of magnetic separator.
Dry magnetic separator feature:
all the magnets are made by rare-earth Nd-Fe-B high-performance materials and high-quality ferrite materials. After a cleverly designed open-circuit, tube scale constituencies can achieve the maximum magnetic induction more than 0.8T, the magnetic field strength of conventional magnetic machine 3-5 times .Cylinder separation refined by the use of wear-resistant stainless steel.
