High quality magnetic separator
PTMS magnetic separation
what is magnetic separation process？
The iron remover is a process of extracting an impurity material from a mixture by using a magnetic force. This separation technique can be used for the mining of iron ore because it is attracted by magnets. Magnetic separation is one of the most reliable methods for removing unwanted ferrous metals during processing of raw materials. From recycling plants to food and pharmaceutical production, we have the perfect industrial magnet to assist with your operation.
Iron removal principle
All materials are magnetic. Substances that are more permeable than air are classified as paramagnetic; those that have lower permeability are called diamagnetic. The paramagnetic material is attracted by the magnet; the diamagnetic material is rejected. Very strong paramagnetic materials can be separated from weakly magnetic or non-magnetic materials by using low-intensity magnetic separators. Minerals such as hematite, limonite and garnet have weak magnetic properties and can be separated from non-magnetic materials by the use of high-strength separators.
The magnetic separation method is based on the difference in mineral magnetic properties, and receives different forces in the magnetic field of the iron remover, resulting in material separation. Mainly used for sorting ferrous metal ore (iron, manganese, chromium); as well as non-ferrous metals and rare metals. The sorting efficiency is high, the processing capacity is strong, and the recovery rate is high. The application of magnetic separation method in the new iron ore dressing plant is very common. The principle of magnetic separation is to select materials that are subjected to mechanical forces such as magnetic force (such as gravity, centrifugal force, friction, medium resistance, etc.) in the sorting space of the iron remover. The magnetic properties of mineral particles are related to the size and magnetic properties of minerals; non-magnetic mineral particles are mainly subjected to mechanical forces. Therefore, the magnetic mineral particles and the non-magnetic mineral particles move along different paths to obtain separation. In general, the magnetic force generated by the magnetic particles is proportional to the strength and gradient of the magnetic field.
There is a magnetic field around the magnetic material. The magnetic field can be divided into a uniform magnetic field and a non-uniform magnetic field. The intensity and direction of each point in the uniform magnetic field are the same; and the intensity and direction in the non-uniform magnetic field are always changing. Mineral particles are only subjected to torque in a uniform magnetic field, and their long axes are parallel to the direction of the magnetic field. In a non-uniform magnetic field, the mineral particles are not only subjected to torque but also to magnetic forces, causing the mineral particles to both rotate and toward the magnetic field gradient. Move and be sucked into the surface of the magnet at the end. Such mineral particles with different magnetic properties can be separated.
