Magnetic roller machine is a type of industrial equipment used for separating magnetic materials from non-magnetic ones. It is commonly used in mining and mineral processing, as well as in recycling and waste management applications.

The machine consists of one or more magnetic rollers that rotate around a stationary shaft. As material is fed onto the rollers, the magnetic field generated by the rollers attracts and holds onto magnetic particles, while non-magnetic particles pass through and are discharged at the end of the roller.

Magnetic roller machines can be used to separate a variety of magnetic materials, such as iron ore, magnetite, and ferromagnetic minerals, from non-magnetic materials such as quartz, feldspar, and calcite. They can also be used to remove magnetic impurities from recycled materials such as plastic and glass.
