Machine Overview
Magnetic Destoner & Magnetic Separator Overview
Swastik Technology’s Magnetic Destoner is a cleaning machine that adds a powerful magnetic stage to stone removal, so iron particles, nuts, bolts and wire pieces are lifted out of the crop together with stones before product reaches the milling, grading and packing equipment. Supplied as a Magnetic Destoner Machine or a Magnetic Separator Machine depending on the line, it is built as an Industrial Magnetic Separator for flour mills, seed plants and groundnut processors. As an established Magnetic Destoner Manufacturer, Swastik Technology builds each unit to the crop, the throughput and the level of contamination the plant actually sees. Known in the trade as a Magnetic Grain Destoner, an Iron Removal Machine or a Magnetic Cleaner, the range also includes a High Intensity Magnetic Separator for lines where the finest ferrous particles must be caught. Every unit is designed to sit neatly beside our Destoner Machine and grading equipment on a complete cleaning line.
Equipment
What Is a Magnetic Destoner?
A Magnetic Destoner is a cleaning machine that combines stone removal with magnetic separation. As product flows through the machine, strong magnets attract and hold ferrous particles such as iron filings, nails, bolt ends and fragments of wire, while stones and other heavy impurities are removed in the destoning stage. Iron gets into crops from harvesting and threshing machinery, from worn parts in transport and handling equipment, and from the field itself, and even tiny fragments can damage milling rollers, chip grader screens and cause quality complaints from buyers.
Every Magnetic Separator works on one simple property: iron is magnetic, and grain, seed and peanuts are not. That is why a magnet catches metal that no screen or air stream can reliably remove, and why it is used as a safety stage, not a replacement for destoning. Where hygiene is specified, a Food Grade Magnetic Destoner uses suitable contact materials and smooth, cleanable surfaces for seed and food applications. Placed ahead of milling, grading or packing, this machine acts as a Ferrous Metal Separator that protects both the equipment and the final product.
How It Works
How Does a Magnetic Separator Work?
1
Feeding
Pre-cleaned grain, seed or peanuts are fed into the machine at an even, controlled rate.
2
Magnetic Field
Product passes through a strong magnetic field that attracts any ferrous particle in the flow.
3
Capture
Iron pieces are drawn out of the stream and held on the magnet surface while clean product flows on.
4
Stone Removal
In the destoning stage, heavier non-magnetic impurities are separated from the crop.
5
Discharge & Cleaning
Clean product leaves the machine, and the captured iron is removed from the magnets at regular intervals.
Machine Advantages
Key Features of Our Magnetic Destoner
Strong magnets that capture iron and other ferrous particles from the product flow.
Combined stone and iron removal in one machine, saving floor space on the line.
Even feed distribution so every particle passes close to the magnetic field.
Robust frame built for continuous, heavy-duty operation.
Easy access to magnets for periodic cleaning of captured iron.
Gentle product flow that keeps seed and peanuts free from damage.
Low power consumption, since the magnetic stage works without extra energy.
Closed construction that limits dust and spillage during operation.
Mild steel or stainless steel contact parts depending on the crop.
Suited to fitting ahead of milling, grading or packing equipment.
Uses
Applications of the Magnetic Separator
Flour Mills & Rice Mills
Protects milling rollers and polishers by removing iron from wheat and paddy before it reaches them.
Groundnut & Peanut Processing
Pulls iron out of in-shell and shelled peanuts ahead of grading and packing.
Seed Companies & Multiplication Farms
Works as a Magnetic Seed Cleaner that keeps metal out of seed lots without damaging the seed.
Grain Storage & Silos
Serves as a Magnetic Separator for Grain, guarding bins and bagging lines against metal.
Sesame & Pulse Cleaning Lines
Removes ferrous particles alongside destoning for cleaner, safer product.
Oil Mills & Crushing Plants
Keeps iron out of the feed to crushers and expellers, where metal causes costly damage.

Frequently Asked Questions
FAQs About Magnetic Destoner
A Magnetic Destoner removes iron and other ferrous particles from seed, grain and peanuts using strong magnets, alongside stone removal, so that clean product reaches milling, grading and packing.
A Magnetic Separator is the general machine that removes ferrous material using magnets. A Magnetic Destoner is a design that combines that magnetic stage with stone removal in one unit.
No. Magnets attract only iron and steel. Stones, soil and glass are not magnetic, which is why a destoner is used alongside the magnetic stage.
Particle size and magnet strength both matter. For lines where the finest ferrous particles must be caught, a stronger magnetic option can be specified, and our engineers will advise on what suits your crop.
Captured iron should be removed at regular intervals, because a heavily loaded magnet loses effectiveness. The right interval depends on how much iron your crop carries.
Yes. Size, capacity, magnetic stage, inlet and outlet positions and construction material are configured to match the crop and the machines on your line.
