Magnetic Separators for Kaolin Purification

It depends on your kaolin, its iron-bearing minerals and particle size. We do not quote a number without a test: send 5–10 kg of kaolin and within 5 days of receiving it we return a report with before-and-after iron content and whiteness.

Wet electromagnetic slurry separators. Published reference figures: the 7A160 Wet Magnet has a theoretical field of about 30,000 GS, a 300 mm magnetic cavity and 10–30 m³/h production rate for slurry below 40 mesh. For larger lines, the published table for the water-cooled D1000 lists a 1000 mm magnetic cavity, 8-inch pipe and a yield of 80–200 (t). We confirm the model from your solids content, particle size and throughput.

Wet electromagnetic slurry separators are designed for weakly magnetic iron-bearing minerals such as iron oxides and mica that ordinary magnets miss, which can raise Fe₂O₃-related whiteness when the feed allows. Results vary by ore mineralogy and liberation; we do not promise titanium reduction. Confirm on your material with a free 5–10 kg pilot test—report within 5 days of receiving samples.

Both keep the coil temperature stable in continuous operation. The water-cooled design circulates (deionized) water through hollow copper tube coils; the published figure for forced cooling is a coil temperature reduction of about 20 °C, which extends coil life. We recommend the cooling type for your duty cycle and site conditions.

Automatically. The slurry valves close, remaining slurry drains back through the return valve, the field is switched off and the matrix is flushed (air ejection and high-pressure water on the slurry series). The matrix has no residual magnetism, so cleaning is fast and complete.

Solids content of the slurry, particle size distribution, throughput (m³/h or t/h), current iron/whiteness and your brightness target. Where the feed varies, we can propose a staged set-up.

A vertical ring high gradient separator runs continuously with a rotating ring, while an electromagnetic slurry separator works in automatic magnetize-and-flush cycles for fine iron. We recommend one after testing your kaolin.

Grids, a kaolin and feldspar matrix or a steel wool matrix, chosen by particle size, flow and how fine the iron is. All are stocked as spare parts.

A published reference on the PTMS-H-B13K89J lists 40–60% solids and capacity of at least 500 kg/h. We confirm the window for your kaolin with a free 5–10 kg sample test, reported within 5 days.

A published reference is slurry below about 40 mesh on the 7A160; coarser feed is usually screened or milled first. We match cavity and matrix to your actual size and solids.

Mainly checking cooling water flow or oil level and temperature, and inspecting the matrix for blockage or wear. Captured iron is removed by the flushing cycle, and spare matrix is available.

On the prepared slurry after grinding and classification, before final bleaching, filter pressing or storage as your flowsheet requires. Published slurry solids reference is about 40–60%. A free 5–10 kg test confirms position and model.

No. SHMP and STPP are dispersants (deflocculants) that help liberate iron in the slurry; the wet electromagnetic separator performs the iron removal. Used together they support higher whiteness. Confirm on your ore with a free 5–10 kg sample test, report within 5 days.

The A65K750J: 750 mm cavity, 0–20,000 GS theoretical field, 0–65 kW adjustable power and oil cooling. Throughput is confirmed after a free 5–10 kg sample test.

It is counter-current flow: slurry enters at the bottom of the magnetic cavity and leaves at the top through the stainless-steel matrix. Published on the A40K530J and A65K750J. Confirm sizing with a free 5–10 kg pilot test, report within 5 days.

After the slurry passes, valves close, residual slurry drains, the field switches off, and air ejection plus high-pressure water flush the matrix. Special meshes leave no remanence, so cleaning is automatic. See the slurry separator series; confirm with a free 5–10 kg pilot test.

No. The separator is one machine in the line. A full kaolin line also covers dispersion, desanding, classification and filter-press dewatering. See the kaolin line design at Magnet China and the PTMS-FP-1250 membrane filter press.

A wet electromagnetic high-gradient separator — the same family as a wet high intensity magnetic separator for kaolin. The model is chosen from your slurry test, not from a generic catalogue size.

It can, but most kaolin lines remove iron at the slurry stage with an electromagnetic slurry separator. For dry-milled kaolin powder, PTMS dry powder separators are an option; a free 5–10 kg pilot test (report within 5 days) shows which route suits your ore.
