Introduction to Magnetic Separation
Separation magnetic equipment is used to remove ferrous tramp metal contaminants from dry particulate, liquids, and slurries in the process of grain, feed, sugar, cereal, chemical, mineral, plastics, oil, textile, salt, pharmaceuticals, and recycled products to name a few. A partial list of Separation Equipment would include magnetic plates, grates, drawers, drums, humps, pulleys, spouts, and belts. These magnetic separators will ensure product purity and protect processing equipment form tramp metal damage.
All materials possess magnetic properties. Substances that have a greater permeability than air are classified as paramagnetic; those with a lower permeability are called diamagnetic. Paramagnetic materials are attracted to a magnet; diamagnetic substances are repelled. Very strongly paramagnetic materials can be separated from weakly or nonmagnetic materials by the use of low-intensity magnetic separators. Minerals such as hematite, limonite, and garnet are weakly magnetic and can be separated from nonmagnetics by the use of high-intensity separators.
Magnetic Separation Methods
Magnetic separators are widely used to remove tramp iron from ores being crushed, to remove contaminating magnetics from food and industrial products, to recover magnetite and ferrosilicon in the float-sink methods of ore concentration, and to upgrade or concentrate ores. Magnetic separators are extensively used to concentrate ores, particularly iron ores, when one of the principal constituents is magnetic. See also Mechanical separation techniques; Ore dressing.
We offers a wide range of magnetic separation products for capturing, controlling and removing ferrous tramp metal contaminants from products and processing systems. Our magnetic separation products are available in standard sizes and strengths with effective designs to meet most conditions and applications.
The feasibility is examined of using high-gradient magnetic separation (HGMS) to recover about 8-nm magnetite nanoparticles that are tailored specifically to extract target solutes (polymer-coated nanoparticles for the extraction of soluble organic contaminants from water and phospholipid-coated particles for the selective extraction of proteins).
A general model for nanoparticle capture based on calculating the limit of static nanoparticle buildup around the wires in an HGMS column is presented.
Choose the suitable Magnetic Separation
Special designs, and engineering assistance are available for difficult applications. Our magnetic separation products are designed for rugged use and easy installation in mechanical, gravity, or pneumatic conveying systems. Optimum performance is achieved when magnetic separators are placed at proper locations within the processing system.
We produce high-quality high-power magnetic separators for most applications, including bulk, grain, dry powders, damp powders, liquids and syrups, which are used in a vast range of industries, including pharmaceutical and food. We can provide custom options, as well as fully custom-built magnetic separators, with turnaround and costs little different to standard products.
