Product Description
Showcasing an outstanding capability for secondary regeneration, our innovative technology achieves a remarkable demoulding rate of ≥25% and ensures an impressive old sand recovery rate of ≥90%. This powerful combination sets new benchmarks in sand regeneration efficiency.
Our state-of-the-art machine leverages the cutting-edge turbo regeneration principle, ingeniously utilizing the friction between sand particles to strip away membrane layers and refine sand into perfectly rounded grains. During the regeneration process, the sand naturally forms a protective cushion layer within the machine's basin, safeguarding it from wear. The robust sand flow efficiently impacts panels to achieve secondary sand regeneration, while a lateral-mounted throttle plate ensures the sand's reliable regeneration without breaking. This process enhances the roundness of sand particles, producing more regular grains. Moreover, our recycled sand significantly reduces the necessity for liquid additives, and the optional secondary air separation mechanism effectively expels inert films and dust from the recycled sand.
Engineered with a sophisticated secondary regeneration mechanism, the machine facilitates a seamless flow of old sand from the upper to the next regenerating basin. After undergoing secondary regeneration, the old sand is directed to the air separator, optimized for superior sand purification.
1. Technical principle and core design
Turbine regeneration dynamics and sand interaction mechanism
Our equipment harnesses the revolutionary principle of turbocharged regeneration. As dual-axis blades rotate at high speeds (720-970r/min), they create a dynamic fluidized sand cushion in the regeneration basin. This innovation enhances friction between sand particles through a self-organizing sand cushion effect, efficiently peeling off resin films (mold release rate ≥ 25%) while minimizing sand particle crushing (crushing rate <5%). This results in a remarkable improvement in sand particle roundness by over 30%. Inspired by the pressurized rubbing technology from Shinto Co., Ltd. of Japan and combined with Luohe Shengmei's patented shock-absorbing bearing seat design, this ensures smooth, stable high-speed operations.
2. Secondary regeneration classification system
First-level regeneration basin: As old sand enters through the feed port, it is meticulously rubbed by dual-axis blades and energized by bottom boiling wind (air volume 3N m³/min) for initial membrane removal. The inert films and dust are effectively channeled to the dust removal system via a side throttle plate, ensuring a pristine first stage of sand treatment.
Secondary regeneration basin: Partially treated sand particles gravitate into the secondary basin, where an anti-wear refraction baffle coupled with an adjustable gap grinding disc design performs deep film stripping through multiple sand flow impacts. The airbag cylinder support structure provides automatic protection against hard objects, ensuring the longevity of equipment components.
Air separation optimization system
Post-secondary regeneration, sand particles are directed into a sophisticated multi-stage air selection device. Here, a controllable airflow (0.3-0.5MPa), generated by a powerful centrifugal fan (15-22kW), meticulously separates micro powder <0.106mm and residual inert films. Our system guarantees an old sand recovery rate of ≥90% and an ignition loss of ≤1.0%, combining the advanced boiling bed technology of Qingdao Binhai Jincheng Company with Shengquan Group's expertise in airflow classification for unparalleled efficiency.
3. Key technological innovations
Wear-resistant and shock-absorbing collaborative design
Crafted with precision, the rubbing blades are fortified with tungsten carbide hard alloy, boasting an impressive service life exceeding 8,000 hours;
The bearing seat is ingeniously designed with a spring-layered buffer structure, achieving a vibration transmission attenuation rate of over 60%. This ingenious solution effectively resolves traditional equipment's vibration-induced sealing failures.
Intelligent control and energy efficiency optimization
Our intelligent system allows precise control of the grinding disc gap (0.5-3mm) by adjusting the lower grinding disc guide nut, enabling adaptation to diverse sand types. For instance, alkaline phenolic resin sand requires a broader gap, demonstrating our commitment to versatile, energy-efficient operations.
Experience unparalleled efficiency with our innovative power configuration, which dynamically adapts to the output requirements. For instance, our 30t/h model operates with a power of just 18.5kW, ensuring optimal performance while slashing energy consumption by an impressive 25% compared to similar equipment.
Embrace the future of sand regeneration with our Composite Regeneration Compatibility, designed to seamlessly integrate diverse processes for enhanced performance.
Our cutting-edge technology expertly processes various types of old sands, including furan resin sand, water glass sand, and alkaline phenolic resin sand. Particularly noteworthy is our advanced approach to handling the resilient film characteristics of alkaline phenolic sand. By utilizing a pioneering process that combines high-temperature pre-baking at 450-730ºC and an innovative chemical release agent, we boldly transcend the constraints of traditional mechanical regeneration techniques, delivering remarkable results.
