Separate Theory of High Gradient Magnetic Cobber

This separating machine is surrounded in a uniform magnetic field produced by the iron-wrapped solenoid. By means of installing some magnetism gathering media such as steel gross and mild steel expanded sheets and magnetization, it will produce towards the surface of the radial direction some magnetic fields with different height which is what we often called High Gradient Magnetic field. This machine is able to produce strong magnetic field force on the condition that the background field intensity is not very strong. In such a field, the paramagnetism material will be influenced by a gravitational interaction in proportion with the product of the additional magnetic field and the magnetic field gradient. Making use of the unique characteristics of this field with different high gradient, we are able to separate some fine material with extremely weak twist magnetic property that is difficult for the general separators to split, and what is more, we are able to reduce significantly the lower limit of the separation granularity which can be decreased to 1μm and at the same time improve the separation index.

This high gradient magnetic cobber can be divided into electromagnetism and permanent magnet these two types and our country mainly manufactures separators with electromagnetism. This high gradient magnetic cobber can be used for separating fine mineral materials with extremely weak magnetic property. In recent years, this machine has outstanding performance in the industrial sewage deposal industry. When it is used for disposing the sewage, the sewage flow past the magnetic media like steel gross and those particles with magnetic property will be absorb on the steel gross, and in this way, the purpose of sewage cleansing will be reached and this machine can also be called high gradient magnetic filter.

At present, the main types of this equipment existing in the domestic market are DMG, SUn, cHAD, D, IMM, YGl—15, SS5—z these seven types. And the 510n type vertical loop loping high gradient magnetic separator has the widest application. This machine is a new and highly efficient ore beneficiation machine that can work in a constant way which making use of the comprehensive force field of the magnetic force, pulsating fluid force and the gravity. It is suitable for classifying of the fine minerals with weak magnetic property such as red iron ore, manganese ore, iron ore, black tungsten titanium and other mineral materials and purifying of the nonmetallic minerals such as kaolin, bauxite, quartz sand weave. Hongxing Machinery is a professional separation equipment manufacturer, other mining machine such as stone crushing and grinding machines, powder grinding equipment and ore dressing machine are all popular products with the best quality and the most competitive prices.
