Permanent magnet is a type of magnet that retains its magnetic properties even when it is not in the presence of an external magnetic field. In a cone crusher, a permanent magnet is used to separate metal particles from the crushed material.
The cone crusher works by crushing the material between an eccentrically rotating cone and a concave bowl. As the cone rotates, it creates a compression force that crushes the material against the concave bowl. During this process, metal particles can become mixed in with the crushed material.
To prevent these metal particles from damaging the crusher or being included in the final product, a permanent magnet is used to separate them from the crushed material. The magnet is positioned above the conveyor belt that carries the crushed material away from the crusher. As the material passes under the magnet, the magnetic field attracts any metal particles, separating them from the rest of the material.
The permanent magnet used in a cone crusher is typically made of a rare-earth material, such as neodymium. These materials have a strong magnetic field and are able to attract even small metal particles. The magnet is designed to be durable and long-lasting, with minimal maintenance required.
In summary, the permanent magnet in a cone crusher is used to separate metal particles from the crushed material. It is positioned above the conveyor belt and uses a strong magnetic field to attract and separate any metal particles. This helps to protect the crusher and ensure that the final product is free of any unwanted metal contaminants.
