Product Description
Our cutting-edge machinery boasts an unparalleled secondary regeneration capability, delivering a remarkable demoulding efficiency of ≥25%, while ensuring an impressive old sand recovery rate of ≥90%.
Harnessing the power of the turbo regeneration principle, this machine ingeniously utilizes the friction between reclaimed sand particles to meticulously remove membranes, achieving perfectly rounded sand grains. During the regeneration process, a protective sand cushion layer forms automatically in the basin, safeguarding it from wear while ensuring complete secondary regeneration. Lateral mounting of the throttle plate guarantees reliable sand regeneration. The result is sand particles with superior roundness and uniformity. Recycled sand significantly reduces the need for liquid additives, and with a secondary air separation mechanism, efficiently eliminates inert films and dust.
This innovative machine features a dual-regeneration mechanism. In the first stage, the upper basin processes old sand, allowing it to seamlessly flow into the subsequent regeneration basin for further refinement. Post-secondary regeneration, the enhanced sand transitions smoothly into the air separator.
1. Technical Principle and Core Design
Turbine Regeneration Dynamics and Sand Interaction Mechanism
Employing the advanced principle of turbocharged regeneration, this technology leverages dual-axis high-speed rotating rubbing blades, achieving speeds of 720-970r/min. This momentum generates a fluidized sand cushion, enhancing the friction between sand particles. Such interaction not only efficiently strips resin films (ensuring a mold release rate of ≥25%) but also minimizes particle crushing (crushing rate <5%), resulting in over 30% improvement in sand particle roundness. This cutting-edge mechanism draws inspiration from the renowned pressurized rubbing technology of Shinto Co., Ltd., Japan, and incorporates Luohe Shengmei's innovative shock-absorbing bearing seat design to ensure stable high-speed operation.
2. Secondary Regeneration Classification System
First-Level Regeneration Basin: Upon entering through the feed port, the old sand is meticulously rubbed by dual-axis blades, complemented by a bottom boiling wind (air volume of 3 Nm³/min), to initiate film removal. Inert films and dust are expertly channeled to the dust removal system via the side throttle plate.
Secondary Regeneration Basin: Gravity guides incompletely treated sand particles into this basin, where an anti-wear refraction baffle and adjustable gap grinding disc design work synergistically. Through multiple panel impact refractions, deep film stripping is achieved, while an airbag cylinder support structure adeptly avoids hard object collisions, safeguarding equipment components.
Air Separation Optimization System
Post-secondary regeneration, sand particles enter a sophisticated multi-stage air selection device. A controllable airflow (0.3-0.5MPa) is generated by a powerful centrifugal fan (15-22kW), effectively separating micro powder <0.106mm and residual inert films, culminating in a final old sand recovery rate of ≥90% and ignition loss ≤1.0%. This design harmonizes the boiling bed technology of Qingdao Binhai Jincheng Company with Shengquan Group's airflow classification expertise.
3. Key Technological Innovations
Wear-Resistant and Shock-Absorbing Collaborative Design
Crafted with tungsten carbide hard alloy, the rubbing blades offer a formidable service life exceeding 8,000 hours.
Equipped with a spring-layered buffer structure, the bearing seat achieves a vibration transmission attenuation rate over 60%, effectively resolving the sealing failures that plague traditional equipment due to vibration.
Intelligent Control and Energy Efficiency Optimization
Fine-tuning the lower grinding disc guide nut allows precise control of the 0.5-3mm gap, adapting effortlessly to diverse sand types, such as alkaline phenolic resin sand, which demands a higher gap.
Experience the revolutionary power configuration of our cutting-edge equipment that intuitively adjusts to match output demands. For instance, our 30t/h model boasts an impressive power capacity of 18.5kW, resulting in a significant 25% reduction in energy consumption compared to competing products. Embrace this advanced efficiency and contribute to a greener future.
