Power Magnetronics manufactures magnetic roller separators for separating ferrous and weakly magnetic contaminants from dry, free-flowing materials. Our magnetic roller separators are designed for applications where controlled material feeding, high magnetic intensity and precise separation are required.
Depending on the application, the separator can be configured with single, double or multiple magnetic rollers. The magnetic system, roller dimensions, belt arrangement and splitter position can be selected according to the material characteristics, feed capacity and required separation performance.
Magnetic roller separators are widely used in food processing, grain cleaning, spice processing, mineral processing, ceramic raw materials, glass materials and other industries where removal of magnetic contamination or recovery of magnetic particles is required.
What Is a Magnetic Roller Separator?
A magnetic roller separator is a continuous dry magnetic separation machine in which material passes over or around a magnetically active roller. Magnetic particles are attracted by the magnetic field while non-magnetic particles follow a different trajectory.
The difference in particle trajectory allows the material stream to be divided into separate fractions.
The final separation performance depends on factors such as magnetic susceptibility, particle size, feed rate, material layer thickness, moisture content and splitter position.
How Does a Magnetic Roller Separator Work?
The feed material is distributed uniformly onto a conveyor belt or suitable feeding system. As the material approaches the magnetic roller, particles that respond to the magnetic field are attracted toward the roller.
Non-magnetic particles continue along their normal trajectory and discharge away from the magnetic zone.
An adjustable splitter is positioned at the separation point to collect the different fractions separately.
For applications requiring higher separation efficiency or product purity, multiple magnetic rollers or multiple separation stages can be incorporated into the system.
