Features:
The separator has no moving parts. The process of separation is carried out in a field of a special configuration. The separator is simple and reliable.
Arrangement:
The barrier magnetic separator consists of a magnetic circuit and some inclined channels 1, which are placed in a gap between poles 2. The walls and bottoms of the channels have smooth surfaces. There are no mechanical obstacles in the way of movement of the separated material in the channels. Thanks to the special inner structure of the walls the gradient of the magnetic field is turned from the bottom perpendicularly towards a stream of separated material which moves inside the channel.
The region where the product of the magnetic field intensity and the gradient of the intensity are greatest (the red line) is placed above the bottom and extends along of length. This is the region of the magnetic barrier 4. Magnetic forces in the magnetic barrier prevent magnetic particles escaping from passing through this region towards the bottom of the channel under the action of gravity.
The material 3 to be separated is fed into the channel above the magnetic barrier 4 along its extent. Non-magnetic particles 5 pass through magnetic barrier onto the bottom of the channel and slide down into a bin 6 for the non-magnetic product. Magnetic particles 7 cannot penetrate through the magnetic barrier. That is why they slide down above the magnetic barrier into a bin 8 for the magnetic product.
Example: Upgrading of pegmatite for production of glass and porcelain.
The barrier separator with two stage of separation in the beneficiation in the Poltava region (Ukraine)
- Size of particles, mm: 0.315–0.063
- The mass yield of the magnetic product, %: 98.2
