Production and Processing of Fine Particles ScienceDirect

The magnetic collection of fine paramagnetic particles requires a high intensity high gradient magnetic field. The most effective method of separation has proven to be Wet High Intensity Magnetic Separation (WHIMS) and High Gradient Magnetic Separation (HGMS). These wet separation techniques utilize high intensity electromagnets and a flux converging matrix. The matrix amplifies the magnetic ...

Fine particle high gradient magnetic entrapment Abstract: The entrapment of fine colloidal paramagnetic (and diamagnetic) particles at magnetic capture centers in the colloid is reviewed. The effect of thermal diffusion on the entrapment from a static colloid is examined in the 1-D and 2-D cases. The latter case allows prediction of captured volumes of colloidal particles. The interparticle ...

Magnetic Particle Theory and Processing Steps

18/07/2011  Magnetic particles containing these characteristics will give maximum response in a leakage field, but will not remain magnetized when the magnetic field is removed. The shape of the magnetic particle should be smooth and must have a high degree of mobility and still have substantial attractive power. There are two types of magnetic particles: Iron Oxides (Iron and Oxygen

Magnetic Filtration Applications and Benefits

Particle capture efficiency by magnetic technology can be narrowed down to these fundamental factors: Particles that are the easiest to separate are large (100 microns vs. 5 microns) and highly magnetic (for example, iron and low-alloy steel). The fluid conditions that best facilitate the separation of magnetic particles are low oil viscosity (ISO VG 32 vs. ISO VG 320 for instance) and low oil ...

Particle size also plays an important part in the behavior of magnetic particles when in a magnetic field, which can be quite weak at a discontinuity. Large, heavy particles are not likely to be held in a weak field when such particles are moving over the surface; therefore, a very small discontinuity may be missed. On the other hand, very fine particles will be held by a very weak field ...

Electrostatic precipitator - Wikipedia

An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...
