How to choose Magnetic Separator for potassium and sodium feldspar iron removal

1. In the process of removing iron from potassium sodium feldspar, the stone is crushed with a crusher of 10mm small particles first, and then washed, the mud is washed away, and then the powder is put into a ball mill, and the ball is milled into 80 mesh slurry. In the process of crushing and ball milling, the mechanical deferring magnetism is strong, and it should be removed first with weak magnetic separation equipment, and then with weak magnetic separation equipment to remove the weak magnetic impurities, if the content of strong magnetic material is large, it is directly used The strong magnetic separation equipment removes iron, and the strong magnetic objects are easy to block the strong separation pipeline, which affects the separation index.

2. For fine-grained or fine-grained minerals, due to the enhanced mutual adsorption between particles, the inclusion of magnetic and non-magnetic materials is serious. If dry separation is used, it is difficult to remove the magnetic materials. In the case of wet sorting, auxiliary methods such as rinsing and pulsation can usually be added to destroy the inclusions between magnetic and non-magnetic objects, effectively increasing the probability of magnetic objects being captured by the magnetic field. It has obvious purification and whitening effect on potassium and sodium feldspar. Wet iron removal is used for fine meshes. After passing through the 80 mesh vibrating screen, adjust the slurry to a concentration of 25%, and then pass the iron remover.

3. The particle size of the material is very important for the separation effect. When the product particle size requirements are met, try to remove iron under coarser particles. Because the finer the particle size, the more the number of crushing times, the more mechanical iron is mixed, the processing capacity of the equipment should be reduced, and the production cost will be increased. Therefore, it is important to choose the appropriate sorting number.

4. The processing flow of non-metallic ore is relatively simple. After the iron removal operation, try not to crush, screen and other operations; in the process design, the magnetic separation iron removal operation should be placed behind as far as possible to avoid impurities Mixed in.

The water-cooling electromagnetic slurry machine produced by Wanjiade Technology Co., Ltd. is a new type of high-efficiency magnetic separator. The circulating pump circulates the deionized water in the hollow copper tube, taking away the heat generated by the energized copper tube. Based on this special structure, the water-cooled electromagnetic slurry automatic iron remover has the following advantages: high magnetic induction strength; small internal temperature and long working cycle; strong adaptability to ore feeding granularity, concentration, high beneficiation efficiency; easy operation and maintenance.

The water-cooling electromagnetic slurry iron remover is suitable for coarse separation of metal ore and purification of non-metallic ore. Quartz, potash feldspar, kaolin, calcium carbonate, gray silica and other non-metallic minerals are purified and removed. Other industries: steel plant, power plant wastewater treatment.
