Product Description
Installed strategically above the sand conveying belt, this innovative system is designed to effectively break up green sand into a loose, workable state after mixing, ensuring optimal readiness for further processing.
Utilized predominantly in the green sand casting mechanized sand recycling production line, this adept machinery is engineered to proficiently loosen mixed wet sand and crush old sand post-separation. It plays a critical role in ensuring the air permeability of molding sand exceeds 80cm³/min while enhancing the surface quality of the casting. As the centerpiece of the sand processing system, the sand loosening machine is revolutionizing modern foundry workshops with its superior loosening, efficient crushing, and intelligent dust removal capabilities. This article will explore in detail how this machinery aids foundry companies in achieving efficient sand resource regeneration and pristine production through innovative technology, adaptive processes, environmental efficiency, and smart controls.
1. Process pain points and technological innovation
To address the challenges of wet sand compaction (3-5% water content) and old sand crushing (with core bone and iron bean impurities), the loose sand machine introduces breakthroughs with its dual-mode crushing structure and modular design:
Wet sand loosening mode:
Rotary knife crushing system: Employing 304 stainless steel staggered blade groups with a hardness of HRC55-60, this system operates at a rapid 1200r/min, processing up to 60t/h. The resultant molding sand boasts a bulk density of ≤1.4g/cm³, with an impressive 40% increase in air permeability.
Dynamic screening module: Featuring a built-in Φ8mm aperture grid, this module achieves synchronous separation of unbroken large particles (return rate <2%), ensuring the molding sand's uniformity as it enters the conveyor belt, with a particle size standard deviation of <0.15mm.
Old sand crushing mode:
Hammer impact mechanism: Outfitted with a high manganese steel hammer head (impact toughness ≥120J/cm²), this mechanism effectively crushes old sand groups with iron beans (diameter ≤20mm), achieving a crushing efficiency of 45t/h and an exemplary iron impurity separation rate of >98%.
Magnetic pre-separation: A robust permanent magnetic roller (magnetic induction strength ≥1500Gs) is positioned to pre-emptively capture ferromagnetic impurities, significantly reducing hammer head wear by 70%.
Intelligent switching technology:
With PLC-controlled one-button switching between wet and old sand processing modes, the system transitions seamlessly in less than 3 minutes, making it ideal for both intermittent and continuous production line setups.
2. Integrated solution for foundry sand processing line
The coordinated operation of the loose sand machine, conveyor belt, and dust removal system creates a powerhouse ecosystem for efficient sand processing:
Space optimization design:
Featuring an inverted installation structure, this apparatus stands elegantly above the B=800-1400mm belt conveyor, with a streamlined net height of ≤1.2m, optimizing workshop vertical space by 30%.
Standardized inlet and outlet flanges (ISO 5211) facilitate seamless integration with sand mixers and old sand screening machines, maintaining a connection precision of ±2mm.
Easy maintenance:
The design of the quick-detachable cutter head and hammer bracket ensures tool changes are swift, taking less than 20 minutes;
Gas spring-assisted observation windows and inspection doors enable single-person completion of routine maintenance with ease and efficiency.
3. Core advantages and economic benefits
Through pioneering material innovation and smart control, the loose sand machine delivers a quantum leap in foundry sand processing performance, driving economic benefits and operational excellence:
Durability redefined: Our design ensures wear-resistance and long-lasting performance.
Engineered for excellence, the blade surface boasts a cutting-edge laser-clad tungsten carbide coating, with a thickness of 0.3-0.5mm, enhancing its durability to last four times longer than standard blades.
Experience significant savings with our replaceable ARQ wear-resistant steel plate lining, offering a hardness of HB450, and slashing your annual maintenance costs by a remarkable 65%.
Optimize your energy efficiency: Our system is designed with energy consumption in mind.
Harness the power of innovation with our 55kW permanent magnet synchronous motor, coupled with a variable frequency drive system, delivering a 25% reduction in electricity usage compared to traditional asynchronous motors.
Our advanced technology ensures that the power consumption for crushing one ton of molding sand does not exceed 0.8kW·h, achieving an impressive 40% reduction compared to conventional roller crushers.
Revolutionizing quality: Presenting compelling improvement data.
Achieve superior casting quality with a compaction rate of loosened sand fluctuating ≤2%, significantly cutting the porosity defect rate from 3.8% to an incredible 0.5%.
Eco-friendly enhancements increase the recycling rate of old sand to 95%, while simultaneously reducing the need for new sand by an outstanding 60%.
