What is Cross Belt Separator ？
Crossbelt Magnetic Separators offer a true self-cleaning industrial magnetic separator system solution for the continuous separation of ferrous contaminants from material flowing on conveyors. Examples include tramp metals, including nuts, bolts in the material being processed. Lateral conveyors provide large area coverage for continuous self-cleaning operation. A durable toothed belt transports ferrous contaminant objects into a collection bin. These separator systems use high-strength suspended plate magnets installed in heavy-duty industrial conveyors operating in an inverted position.
How Cross Belt Separator Work？
A cross belt separator is a specialized type of magnetic separator that operates on the principle of electromagnetism. The device consists of a conveyor belt with a magnetic field generated by an electromagnetic coil located above it.
As the conveyor belt moves along, the magnetic field attracts and separates magnetic particles from the non-magnetic ones, allowing for effective and efficient separation of ferrous materials from non-ferrous materials.
The electromagnet is powered by a rectifier, which transforms AC voltage to DC voltage required by the coil. When the current flows through the coil, a magnetic field is generated, which attracts and captures magnetic particles and separates them from the material on the conveyor belt.
The captured ferrous material is then transported to a collection bin or chute by the conveyor belt, while the remaining non-magnetic material continues to move along the conveyor.
Magnets used in Cross Belt Separator？
Cross-belt separators use powerful magnets to attract and separate ferrous contaminants from conveyed material. These magnets are usually ceramic or rare earth magnets. Ceramics mainly refer to ferrite ceramics, and rare earth magnets refer to powerful permanent magnets composed of rare earth element alloys. Related research began in the 1970s and 1980s. Among the permanent magnets, rare earth magnets can generate the largest magnetic field, and the most common are the following two types: neodymium magnets (also known as NdFeB magnets) and samarium cobalt magnets. The two magnets contain neodymium and samarium in rare earth elements respectively. . The material of rare earth magnets is very brittle and susceptible to corrosion, so other metals are generally coated on the outer layer to protect the rare earth magnet itself. Rare earth magnets can generally generate a magnetic field in excess of 1.4 tesla, while ferrite or ceramic magnets are only about 0.5 to 1 tesla.
Applications of Cross Belt Separator？
1.Mining: Removal of metal scraps, bucket teeth, rebar and other tramp metal from production to prevent damage to downstream process equipment such as conveyor belts, pumps, screens, and hydrocyclones.
2.Aggregate: Extracting tramp metal such as rebar, metal scrap, and tools from conveyed crushed rock.
3.Wood: Removing ferrous materials such as wire, tools, and metal scrap to protect chippers and hogs.
4.Biomass: Ensuring metal free products such as wood pellets while protecting equipment from tramp metal.
5.Recycling: Prevents metal contamination in final product and protects comminution equipment from damage.
