Basic Composition and Production Process

Composition Parameters: Silicon content controlled at 14%-16%, iron content at 80%-83%, with strict impurity requirements: carbon <0.6%, sulfur <0.02%, phosphorus <0.03%, manganese <0.8%; density can reach 6.7-7.1 g/cm³, Mohs hardness 5.5-6.0, magnetic content ≥99%.

Production Process: First, low-silicon ferrosilicon alloy is obtained through electric furnace smelting, then crushed through a large-scale crushing and grinding production line, and finally processed into finished product through multi-layer fine sieving. Common particle sizes include 65D, 100D, 150D, 270D, and 70 mesh, 100 mesh, 200 mesh, 325 mesh, etc., and can be customized upon request.

Product Characteristics
The product is in irregular powder form, offering significant advantages over ordinary crushed low-silicon iron powder:

* **Wear Resistance and Pulverization Resistance:** The dense crystal structure without loose pores provides strong resistance to mechanical abrasion and slurry erosion. During continuous use, it maintains a high particle size retention rate, reducing monthly loss by over 35% compared to ordinary products, thus minimizing refueling frequency.

* **Good Recyclability and Reusability:** Possesses strong magnetism, ensuring a stable magnetic separation recovery rate of over 95% after mineral processing. It can be recycled multiple times, significantly reducing raw material costs for enterprises.

* **Other Advantages:** High specific gravity, oxidation resistance, and high hardness allow for stable maintenance of suspension density, ensuring separation accuracy. Suitable for high-wear, long-cycle continuous operation scenarios.
