Product Description
Our machine boasts an exceptional ability for secondary regeneration, achieving a de-moulding efficiency of ≥25% and an impressive old sand recovery rate of ≥90%. Experience unparalleled consistency and performance with every use.
Embrace the cutting-edge turbo regeneration principle, ingeniously utilizing the friction between sand particles to achieve thorough membrane removal and superbly rounded sand grains. Meanwhile, the regeneration basin forms a protective cushion layer, safeguarding against wear. Our innovative design ensures precise secondary regeneration, with uniquely mounted throttle plates that assure the reliable regeneration of sand without breakage. The result? A more uniform, spherical grain that significantly reduces the need for additional liquid materials. Our enhanced air separation mechanism effectively expels inert films and dust, delivering pristine recycled sand primed for optimal efficiency.
This state-of-the-art machine features a robust secondary regeneration system, allowing the upper basin's rejuvenated sand to seamlessly transition into the next regeneration stage. Following secondary refinement, the rejuvenated old sand naturally progresses to the air separator unit for final processing.
1. Technical principle and core design
Turbine regeneration dynamics and sand interaction mechanism
Harnessing the turbocharged regeneration principle, our equipment features dual-axis rubbing blades rotating at high speeds (720-970r/min), creating a dynamic fluidized sand cushion. This ingenious mechanism enhances inter-particle friction within the sand cushion, efficiently removing resin films (boasting a mold release rate of ≥25%) while minimizing sand particle breakage (crushing rate <5%). The result is a remarkable over 30% improvement in sand grain roundness. Drawing inspiration from Shinto Co., Ltd.'s pressurized rubbing technology and incorporating Luohe Shengmei's shock-absorbing bearing seat design, we ensure unwavering stability at high speeds.
2. Secondary regeneration classification system
First-level regeneration basin: As old sand enters via the feed port, the dual-axis blades and bottom boiling wind (air volume 3N m³/min) perform initial film removal. Inert films and dust are expertly channeled to the dust removal system via the side throttle plate, ensuring a pristine regeneration process.
Secondary regeneration basin: Unsurpassed in its precision, this basin employs an anti-wear refraction baffle and adjustable gap grinding disc design. Sand flows naturally into this phase, where multiple refractions achieve deep film stripping. The airbag cylinder support adds an extra layer of protection, intelligently avoiding hard objects to safeguard vital components.
Air separation optimization system
Innovative multi-stage air selection awaits the sand particles post-secondary regeneration. Our centrifugal fan (15-22kW) generates a meticulously controlled airflow (0.3-0.5MPa), expertly segregating micro powders <0.106mm from residual inert films. This intricate design achieves an outstanding old sand recovery rate of ≥90% and ignition loss ≤1.0%, integrating Qingdao Binhai Jincheng's boiling bed technology with Shengquan Group's airflow classification prowess.
3. Key technological innovations
Wear-resistant and shock-absorbing collaborative design
Crafted with precision, the rubbing blades are welded with tungsten carbide hard alloy, extending their service life beyond an extraordinary 8,000 hours, ensuring durability and reliability.
Enhanced with a spring-layered buffer structure, our bearing seat achieves a vibration transmission attenuation rate exceeding 60%, effectively resolving sealing failures associated with traditional equipment vibrations.
Intelligent control and energy efficiency optimization
Our precision engineering allows the lower grinding disc guide nut to be finely adjusted, maintaining a 0.5-3mm gap to accommodate varying sand types. Tailor your machine for specific needs, like the higher gap requirement for alkaline phenolic resin sand, ensuring unmatched adaptability and efficiency.
The innovative power configuration seamlessly adapts to the dynamic output requirements. For instance, our 30t/h model is driven by a robust 18.5kW power unit, achieving a remarkable reduction in energy consumption by 25% compared to similar equipment in the industry. This not only contributes to significant cost savings but also underscores our commitment to sustainable and efficient technological advancements.
Unparalleled Composite Regeneration Compatibility
Our advanced system is engineered to proficiently handle a diverse array of old sands, including furan resin sand, water glass sand, and the particularly challenging alkaline phenolic resin sand. For sands exhibiting the resilient film properties of alkaline phenolic sand, our pioneering approach employs a strategic synergy of high-temperature pre-baking, ranging from 450 to 730ºC, coupled with a specialized chemical release agent. This revolutionary method triumphs over the constraints faced by conventional mechanical regeneration techniques, offering unparalleled efficiency and effectiveness.
