Fly ash, also known as flue-ash, is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. Ash which does not rise is termed bottom ash. In an industrial context, fly ash usually refers to ash produced during combustion of coal. Fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants, and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the source and makeup of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline) and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata.
In Russia, there are many suppliers of magnetic separation equipment. Shanghai SBM is a professional mining machine manufacturer and supplier in the world, which can offer you many kinds of mining processing machines. If you have any needs, please contact us.
Magnetic separation machine has the best performance in practice. It is equipped with the most technologically advanced high intensity magnetic separation equipment. This machine has reached the double advantages of high concentrate grade and high yield in separating magnetic ores.
SBM has produced several thousand Low Intensity magnetic separators both dry and wet versions to the iron ore and others mining industry. SBM has (in close co-operation with the iron ore mining Industry) developed and designed the low intensity magnetic separators to meet the highest demands for capacity, metallurgical performance and mechanical availability.
The applications of the machine are hematite, limonite, siderite, ilmenite, chromite, wolframite, tantalum and niobium ore, and other weakly magnetic minerals beneficiation; quartz, feldspar, nepheline, fluorite, sillimanite, spodumene and other non-metallic minerals to remove iron, and purification.
