Product Description
Introducing a groundbreaking innovation in magnetic separation technology! Our Customizable Through-Type Magnetic Separator, designed by Qingdao Sanzhuji Technology Co., Ltd., utilizes a permanent magnet block meticulously crafted from strontium ferrite through advanced powder metallurgy. This exceptional equipment is engineered to effortlessly extract iron impurities such as iron beans, nails, and casting splinters from old sand with unrivaled precision.
In the delicate process of foundry sand regeneration, the presence of iron impurities like iron beans, nails, and flash poses a threat to casting quality, leading to undesirable defects such as pores and slag inclusions, ultimately impacting production efficiency. Our state-of-the-art separator, featuring an innovative annular permanent magnetic pole array and employing strontium ferrite, achieves an astounding 99.5% iron removal rate. This in-depth exploration will reveal how this pioneering equipment redefines sand processing standards, offering zero energy consumption, through breakthroughs in magnetic source technology, structural innovation, process efficiency, and versatile industry applications.
1. Technical principles and core design breakthroughs
Harnessing the exceptional magnetic properties of strontium ferrite (SrFe12O19), our equipment achieves revolutionary breakthroughs tailored to the demanding conditions of foundry sand processing, through the innovative use of an annular magnetic pole array and a meticulously engineered gradient magnetic field:
Innovation of permanent magnetic source:
The strontium ferrite magnet block, possessing remarkable density (≥4.8g/cm³) and remanence (Br≥410mT), is engineered via a sophisticated wet pressing process. Its outstanding magnetic energy product (BH) max≥3.5MGOe and coercive force Hc≥320kA/m ensure an unwavering magnetic field with an annual attenuation rate of less than 0.1%;
The magnetic poles, arranged in precise concentric circles with optimal pole spacing of 4-8mm, create a powerful radial gradient magnetic field (0.4-1.2T). This design enhances the adsorption force on iron impurities, tripling the efficiency compared to traditional electromagnetic systems.
Structural optimization design:
Our meticulously modular assembly of annular magnetic poles allows for customizable diameters ranging from Φ600 to 2000mm, perfectly fitting sand conveying systems with varying bandwidths (500-2000mm);
Featuring a robust 304 stainless steel protective cover (IP66 grade) with an integrated guide plate, the system permits adjustable sand flow speeds from 0.8 to 2.5m/s, ensuring an impurity separation rate exceeding 99.5%.
Intelligent control system:
Equipped with a cutting-edge magnetic sensor, the system monitors magnetic field strength in real-time, seamlessly calibrating the conveyor belt speed (accuracy ±2%) via an integrated inverter;
Incorporating an advanced Internet of Things module, our system uploads vital operational data (temperature, iron removal, etc.) and is fully compatible with MES system integration for enhanced operational efficiency.
2. Core advantages and industry value
Setting a new benchmark, our equipment surpasses traditional electromagnetic iron removers by leveraging the sustainable attributes of permanent magnets, offering zero energy consumption while capitalizing on the unique properties of strontium ferrite material:
High-efficiency iron removal performance:
Effortlessly capturing minuscule iron impurity particles as small as 0.2mm, our system achieves an iron bean (Φ1-20mm) removal rate exceeding 99.8% and a micro-iron powder (50-200μm) removal rate of over 95%;
With an impressive sand processing capacity of 10-80t/h, the system reduces the iron content in old sand from 0.5-5% to a mere <0.02%, revolutionizing processing capabilities.
Energy saving and environmental protection:
Our cutting-edge permanent magnet drive eliminates the need for an excitation power supply, resulting in zero power consumption per ton of sand processed, translating to over 200,000 yuan in annual electricity savings (based on a 10t/h capacity);
The recyclability of strontium ferrite materials is an impressive ≥90%, significantly reducing the equipment's life cycle carbon emissions by 60% compared to rare earth magnets.
Durable and low maintenance:
Our customizable through-type magnetic separator features a high temperature resistant design, operating seamlessly at temperatures reaching up to 180ºC. With an impressively low magnetic property attenuation rate of less than 1% per 100ºC, it ensures optimal performance even under intense heat.
Equipped with a sophisticated self-cleaning scraper, featuring a durable tungsten carbide coating, and a quick-release magnetic module, this product assures minimal maintenance. Enjoy the convenience of upkeep requiring less than one hour per year.
3. Seamlessly integrated application for comprehensive foundry sand treatment, enhancing efficiency and performance throughout the entire process.
Old Sand Regeneration System:
By integrating with a vibrating screen and sand cooler, we establish a streamlined 'screening-iron removal-regeneration' production line. This innovation dramatically boosts the reuse rate of old sand to an impressive 95%.
Our advanced technology eliminates subcutaneous pores in castings caused by iron impurities, elevating surface smoothness by optimizing roughness from Ra12.5μm to Ra6.3μm, ensuring superior quality.
Adaptable to Multiple Processes:
In resin sand treatment, our corrosion-resistant magnetic pole protective layer effectively prevents resin acid corrosion, maintaining a consistent stripping rate of less than 0.3%.
For water glass sand regeneration, the optimized magnetic field distribution prevents micro powder agglomeration, with sand particle roundness reaching a commendable ≥0.85, ensuring superior material quality.
Economic Benefit Data (Illustrated with an enterprise producing 50,000 tons of castings annually):
Achieve substantial cost savings by reducing casting scrap losses by 5 million yuan annually, alongside saving 2 million yuan in new sand procurement expenses.
Our zero power consumption design not only boosts energy efficiency but also contributes to sustainability by reducing carbon emissions by 150 tons annually, aligning with stringent ESG compliance standards.
