Product Description
This innovative equipment utilizes a cutting-edge permanent magnet block as its magnetic source, artfully arranging the magnetic poles in a circular configuration using the specialized strontium ferrite powder metallurgy product. It masterfully eliminates iron impurities such as iron beans, nails, and casting splinters embedded within old sand, ensuring pristine sand quality.
In the intricate foundry sand regeneration process, iron impurities like iron beans, nails, and flash can severely compromise casting quality, leading to defects such as pores and slag inclusions, thereby impacting production yields. This exceptional equipment, featuring an annular permanent magnetic pole array and advanced strontium ferrite powder metallurgy materials, excels in the efficient separation of ferromagnetic impurities from old sand. This article delves into how this equipment revolutionizes sand processing standards with a remarkable 99.5% iron removal rate and zero energy consumption, exploring the realms of magnetic source technology, innovative structural design, process enhancement, and diverse industry applications.
1. Technical principles and core design breakthroughs
Leveraging the unique magnetic properties of strontium ferrite (SrFe12O19) and addressing the demanding requirements of foundry sand operations, the equipment achieves groundbreaking advancements through its annular magnetic pole array and gradient magnetic field design:
Innovation of permanent magnetic source:
Crafted with precision, the strontium ferrite magnet block (density ≥4.8g/cm³, remanence Br≥410mT) is created using a sophisticated wet pressing process, boasting a magnetic energy product (BH) max≥3.5MGOe and a coercive force Hc≥320kA/m, ensuring unparalleled stability of the magnetic field with a minimal annual attenuation rate of <0.1%;
Ingeniously arranged in concentric circles (pole spacing 4-8mm), the magnetic poles generate a radial gradient magnetic field (magnetic field strength 0.4-1.2T), enhancing the adsorption force of iron impurities by threefold compared to traditional electromagnetic types.
Structural optimization design:
The modular assembly of annular magnetic poles supports highly customizable diameters from Φ600 to 2000mm, seamlessly integrating into sand conveying systems with varied bandwidths (500-2000mm);
The robust 304 stainless steel protective cover (IP66 grade) features a built-in guide plate, allowing adjustable sand flow speeds from 0.8 to 2.5m/s, achieving an impurity separation rate of over 99.5%.
Intelligent control system:
Equipped with a magnetic sensor that monitors magnetic field strength in real-time, and an inverter that dynamically adjusts the conveyor belt speed with precision (accuracy ±2%);
Enhanced with an Internet of Things module, the system uploads vital equipment operation data (temperature, iron removal, etc.), and seamlessly integrates with the MES system.
2. Core advantages and industry value
Surpassing electromagnetic iron removers, this equipment delivers multi-dimensional advantages with its permanent magnet zero energy consumption and exemplary strontium ferrite material properties:
High-efficiency iron removal performance:
Capable of capturing minuscule iron impurity particle sizes down to 0.2mm, achieving an iron bean (Φ1-20mm) removal rate of over 99.8%, and a micro-iron powder (50-200μm) removal rate exceeding 95%;
With a robust sand processing capacity of 10-80t/h, the equipment reduces the iron content of old sand from 0.5-5% to an impressive <0.02%.
Energy saving and environmental protection:
The ingenious permanent magnet drive operates without an excitation power supply, rendering the power consumption per ton of sand processing effectively zero, translating to an annual savings of over 200,000 yuan in electricity costs (based on a 10t/h production capacity);
Featuring a recyclability rate of strontium ferrite materials of ≥90%, the equipment reduces carbon emissions throughout its lifecycle by an impressive 60% compared to rare earth magnets.
Crafted for endurance and minimal upkeep:
Engineered to withstand high temperatures (operational threshold of ≤180ºC), this remarkable design boasts an exceptionally low magnetic property attenuation rate of <1%/100ºC;
Featuring a self-cleaning scraper with a durable tungsten carbide coating and a quick-release magnetic module, it ensures maintenance is a breeze, taking less than 1 hour annually.
3. Comprehensive integration in the entire foundry sand treatment process
State-of-the-art sand regeneration system:
Seamlessly linked with a vibrating screen and sand cooler, this system crafts an integrated line of 'screening-iron removal-regeneration,' elevating the old sand reuse rate to an impressive 95%;
Effectively eradicates subcutaneous pores in castings caused by iron impurities, refining surface smoothness from Ra12.5μm to an optimal Ra6.3μm.
Versatile adaptation across multiple processes:
In resin sand treatment, a corrosion-resistant magnetic pole protective layer remarkably withstands resin acid erosion, maintaining a stripping rate fluctuation below 0.3%;
For water glass sand regeneration, an optimized magnetic field distribution prevents micro powder clumping, achieving a sand particle roundness of ≥0.85.
Economic advantages (illustrated by a company with an annual casting output of 50,000 tons):
Cost efficiency: Slash casting scrap loss costs by 5 million yuan annually and trim 2 million yuan off new sand procurement expenditures;
Energy and environmental benefits: With a zero power consumption design, it remarkably cuts carbon emissions by 150 tons yearly, aligning with ESG compliance standards.
