Ceramic ferrite magnets

Ferrite magnets are permanent magnets made predominantly of ceramic materials, particularly iron oxide combined with barium or strontium compounds. They are characterized by their high corrosion resistance, robustness, and cost-effective production, but have a lower magnetic energy density compared to rare-earth magnets. Due to these properties, they are used in numerous applications – from loudspeakers and electric motors to refrigerators and other electrical devices.

Ferrite magnets are relatively brittle compared to other magnetic materials. This means they break or splinter easily under mechanical stress. This property is advantageous for crushing, as the material typically breaks into small particles, but appropriate methods must be chosen.

Due to their brittleness, mechanical crushing methods such as hammer mills or precision crushers are suitable. These machines use impact forces to break the magnets into smaller pieces without introducing significant contaminants.
It is also important to ensure that the magnetic properties are not impaired during crushing.
