CONSTRUCTION FEATURES:
There are no moving or rotating nodes, separation is achieved due to the special configuration of the magnetic field.
ADVANTAGES OF USE:
- Low cost of maintenance, repair and spare parts;
- Sustainable technology performance;
- Low power consumption;
- Lack of industrial product;
- High, more than 99% recovery of magnetic product.
DEVICE AND PRINCIPLE OF THE SEPARATOR:
In the barrier magnetic separator, enrichment is carried out continuously in the fixed channel 1, a longitudinal section of which is shown in the figure. The walls, bottom and ceiling of the channel have smooth surfaces. There are no mechanical obstacles to the movement of grains of the enriched material along the channel. A magnetic field gradient is created in the channel, directed from the bottom perpendicular to the direction of flow of the separated material moving inside the channel.
The region where the product of magnetic induction by its gradient is the largest is located above the bottom and extends over the entire length of the channel. This is the area of the magnetic barrier (red line). The channel is located between the pole pieces 2 of the magnetic system.
The material 3 to be enriched is fed into the channel above the region of the magnetic barrier 4 along its strike. Non-magnetic grains 5 under the influence of gravity pass through the magnetic barrier to the bottom of the channel and slides down into the receiver 6 of the non-magnetic product. Magnetic grains 7 cannot penetrate the magnetic barrier. Therefore, they slide down over the magnetic barrier into the receiver 8 for the magnetic product. Thus, due to the magnetic barrier, the stream of enriched material is divided into flows of magnetic and non-magnetic particles.
The material to be enriched is tested for enrichment in a laboratory barrier separator.
PEGMATITE CLEANING FOR THE PRODUCTION OF GLASS AND PORCELAIN.
A two-tier separator is used for pegmatite cleaning by GeoResurs LLC (Poltava region). The size of pegmatite is 0.8 – 0.05 mm.
- Separator capacity – 6 t / h;
- The yield of purified pegmatitis is 98.2%;
- The content of Fe 2 O 3 in the initial one is 2.01%, in the purified one – 0.04%;
- The content of Fe 2 O 3 in a non-magnetic product is only 0.04%, that is, less than what GOST 13451-77 requires.
DIVISION OF ILMENITE CONCENTRATE ON THE CONTENT OF TIO 2 ON THE IRSHAN GOK
Ilmenite concentrate with a TiO2 content of 60.3% is divided into three ilmenite fractions according to the TiO 2 content:
- Low titanium fraction with TiO 2 content – 58.8%;
- Mid-titanium fraction with TiO 2 content – 59.3%;
- High-titanium fraction with TiO 2 content – 64.1%;
