Magnetic separators are used to purify and separate process streams in industries such as mining and science labs. They come in various styles and sizes, from tabletop separators to massive drums. They can remove tramp metal, sort various types of metal, and prevent equipment damage. Proper maintenance is necessary for effective use.
Magnetic separators are devices designed to facilitate the purification and separation of process streams. They are used in industries such as mining, and smaller versions are used in science labs to process certain types of samples. A number of companies make magnetic separators for various applications, and there are several styles to choose from, depending on the application and their needs. This type of equipment is available from companies that specialize in industrial processing equipment, and can also be ordered directly from manufacturers, in cases where people have customized needs.
A basic magnetic separator consists of a magnet of some kind. As materials are passed under, over, through or around the magnetic separator, it attracts unwanted impurities, pulling them out and cleaning the process stream. Magnetic separators can be either ferromagnetic or paramagnetic, depending on your needs, and in some cases materials will be passed through both types of magnetic separators. These devices can range in size from the tabletop separators used in laboratories to the massive drums used in recycling plants.
One of the common uses of a magnetic separator is to remove so-called tramp metal, undesirable iron that can foul a process stream. Magnetic separators are also used to remove materials that could damage or soil equipment, in a pre-processing stage. The separators can also be used to sort various types of metal, with a series of separators of varying strengths to extract strongly and weakly magnetic materials at different times.
Some design styles include hanging magnets, which hover over a process stream, and magnetic plates, which allow materials to flow onto the plate as you extract magnetic materials. Magnetic separators can also take the form of stacked drums, racks and trays through which material flows. In the laboratory, a magnetic separator can be designed to accommodate flasks and other containers used to hold material in the laboratory, to reduce the risk of cross-contamination.
Like other devices used in material processing, a magnetic separator must be properly maintained and used as directed to be effective. Maintenance includes cleaning the separator to remove any magnetic materials it has collected, along with periodic lubrication of moving parts. In the case of electromagnets, it is also necessary to ensure that emergency stops and other safety functions are in working condition, so that the magnet can be switched off in the event that a problem occurs on the production line.
