The principle of magmetic separator is to use a variety of magnetic ores or materials magnetic difference in the effect of magnetic and other forces under selection. Magnetic separation can be divided into dry and wet magnetic separator.Common dry magnetic separation equipment: Dry weak magnetic separator (separator, magnetic pulley), dry strong magnetic separator (permanent roller separator, electromagnetic iron machine). Separator is mainly used to remove from the feed stream doped iron or iron filings. There are two kinds of electromagnetic and permanent magnet. Fixed belt hanging and hanging two kinds. Magnetic pulley for large (10-120mm) strong magnetic ore preselection can choose mixed ores of rock, down raw ore dilution appearance, usually used in ore crushing coarse crushing and end after the goods into the mill on pre-sorting. Primary effect is to get rid of unwanted waste rock, and progress into the mill ore grade, cut into the grinding mill of the amount, and then decreased grinding costs. Grinding ore production costs throughout a proportion reached 60% -70%, while the dry magnetic throw away the tail pulley can be pre-deposit rate as high as 15% -20%.
Permanent Magnetic Separator is the use of a plant over ordinary wet magnetic separation equipment, according to the bottom box layout and the flow of goods into downstream is not the same type, counterflow and semi-countercurrent type three. Use up to half counterflow. Magnetic dehydration tank features are: simple layout, no working parts, protective facilities, simple operation, disposal to big, do not consume solenoid. Defects can not be drained coarse gangue. Mainly used to remove fine gangue and slimes, sometimes used dewatering. Whether wet or dry separation election to select the time separator must identify yourself to magnetic minerals is what material is suitable for what kind of processing methods, so as to achieve more with less.
