Operating Principle
The principle (simplified) equation for the magnetic attraction force on a particle is: Fm=Const. xVxXxHx grad HV is particle volume X is particle magnetic susceptibilityH is magnetizing field grad H is magnetizing gradient
From this fundamental equation is evident that with homogenous magnetic fields (grad H = 0) there is no resulting attraction force on the left particle. This is illustrated where the left part show the undisturbed and the right part a disturbed field. Field gradient is show here by the varying distance between field lines. Any sharp edge of small dimension will cause such a field distortion, and hence an increased gradient. The famous illustration of this is an ordinary permanent horse-shoe magnet and iron file achieving. Here the achieving will stick mostly to the edge of the poles due to the increased gradient.
The Star Trace High Gradient Magnetic Separator design
is a reversal of a normal electric "bar" magnet. This overcomes many of the imitations of working within the air gap of the conventional horse a hoe shape. The most important advantage is that the return frame cross-section can be increased to cope with higher field strengths without saturation.
The resulting homogenous magnetic field inside the solenoid is then manipulated inserting varying types of matrices into the canister. The type of matrix is a function of feed particle size. For coarser particle (up to 1mm) a grid of expand metal is used, and for very fine particle sizes (clay), steel wool is used. Matrix material is either stainless steel or another ferromagnetic material. In this way field strength, field gradients, and matrix flow-through capabilities can be optimized for each case.
The magnetic separator is cyclic or discontinuous, since it must be stopped and demagnetized for flushing out the trapped magnetic particles. It use is therefore limited to feeds with low enough magnetic content, to permit acceptable cycle times. For applications with higher contents of magnetic a continuous variety of this principle, the High Gradient Magnetic Separator carousel, is available.Optimum operating condones should be established from lab tests on representative samples
Laboratory and small Pilot Scale Cyclic High Gradient Magnetic Separator
Our High Gradient Magnetic Separator Modes 10- 15- 20 10 cm bore Cyclic Laboratory and small pilot scale High Gradient Magnetic Separator is used in star Trace's standard laboratory tests to establish the separations conditions in mineral processing or purifications and water treatment problems. Determination of the combined effects of the systems operating variable on separation or filtration efficiency is required to minimize cost of a full scale system. This system is easily transportable for small scale on-site pilot testing.
15 THP Continuous High Gradient Magnetic Separator and Mineral Processing Pilot PlantThe Star Trace- HGMS carousel
Continuous High Gradient Magnetic Separator can process from 1 to 15 tons of one per hour. As part of Star Trace's mineral processing pilot plant, the Carousel may be incorporated in a flow sheet that includes crushing, grinding and classifying equipment. Thickeners permit the Carousel products to be rerun simulating multistage flow sheets. A pilot carousel may be leased separately for on-site pilot testing.Magnetic Filters
Star Trace - HGMS high gradient magnetic filters are designs to remove ferromagnetic and ever weekly magnetic corrosion products such as iron and copper from thermal power reticulating and process waters at temperatures up to 400 C and pressures up to 275 bar. Corrosion product reductions to less than 0.01 pp, have been obtained. Our company High Gradient Magnetic Filter is cyclic, automatic back flushing filters operating in alternate feed and flush modes. Typical duty cycle feed times are days or weeks, flushing requires only fractions of a minute. Back flush volumes are small and solids settle easily. As a protective measure, feed flow to the filter may be bypassed during the flush cycle.
Star Trace filter systems have long service life with negligible maintenance. The magnetic filter has no moving parts to wear out and the fixed durable filter medium is either stainless steel or another ferromagnetic material chosen for its low corrosion factor. Standard sizes are the same as for the cycle HGMS range. Max capacity for size 214 is 800-4000m3/h pressure drops of less than 4 Bar.Star Trace HGMS CarouselsSpecifications
Basically the same as for the cyclic device, with the exception that the magnet coil is flared at both ends to permit the passage of the matrix ring. Rubber seals are used to prevent leakage in the magnet head.

Star Trace High Gradient Magnetic Separator (HGMS) carousel Magnetic Separators can be used for many applications including the processing of iron ores, rate earth, industrial minerals, coal (desulfurization and de-aching), and chemical waste. In addition to the strongly magnetic compounds of Fe, Co, and Ni a vast number of more weakly magnetic compounds, which are not normally treated by ordinary magnetic separation, may be processed by high gradient magnetic separator.
STR- High Gradient Magnetic Separator (HGMS) are able to remove ever very weakly paramagnetic materials. A number of extremely effective applications includes: increase of the GEB of kaolin clay, reduction of copper in molybdenum concentrates and of Fe2O3
in sands, barites and ceramic clays; the purification of coal, materials and phosphates.Notes
