Product Description
Empowered with an extraordinary secondary regeneration capacity, our system boasts a remarkable demoulding rate of ≥25%, coupled with an impressive old sand recovery rate of ≥90%. This ensures efficiency and sustainability, redefining expectations in sand regeneration.
Leveraging the innovative turbo regeneration principle, our advanced machinery orchestrates the intricate interplay of sand particles. Through strategic rubbing, it effortlessly strips the membrane and rounds off sand grains. Within the regeneration basin, a protective cushion forms automatically, safeguarding against wear while the solid sand flow impacts panels to facilitate secondary regeneration. The lateral-mounted throttle plate ensures reliable sand regeneration, preserving sand integrity and enhancing roundness. The recycled sand proficiently minimizes liquid material usage, complemented by an optional secondary air separation mechanism that efficiently eliminates inert film and dust.
Our machine features a sophisticated secondary regeneration mechanism where the upper basin seamlessly transitions the rejuvenated old sand into the subsequent regeneration basin. Post-regeneration, the sand elegantly flows into the air separator part, optimizing the entire process.
1. Technical principle and core design
Revolutionizing the industry, our turbine regeneration dynamics and sand interaction mechanism harmonize technology with nature, ensuring unparalleled efficacy.
Embracing the turbocharged regeneration principle, our equipment utilizes dual-axis high-speed rotation blades (achieving speeds of 720-970r/min) to craft a dynamic fluidized sand cushion. This heightens friction strength, efficiently peeling off resin films (mold release rate ≥ 25%) while preventing particle crushing (crushing rate <5%). The result is an impressive 30% boost in sand particle roundness. Inspired by Shinto Co., Ltd. of Japan and integrating Luohe Shengmei's patented shock-absorbing bearing seat design, we ensure stable and high-speed operation.
2. Secondary regeneration classification system
First-level regeneration basin: As old sand enters via the feed port, it undergoes dual-axis blade rubbing and bottom boiling wind treatment (air volume 3N m³/min), achieving initial film removal. The inert film and dust are expertly redirected to the dust removal system through the side throttle plate.
Secondary regeneration basin: Sand particles gravitate into this advanced secondary basin, where the anti-wear refraction baffle and adjustable gap grinding disc expertly manage deep film stripping. The sand flow impacts the panel multiple times while the airbag cylinder support structure automatically shields equipment components from hard impacts.
Air separation optimization system
Post-secondary regeneration, sand particles advance into a meticulously designed multi-stage air selection device. A centrifugal fan (15-22kW) at the base generates a precision-controlled airflow (0.3-0.5MPa), effectively separating micro powder <0.106mm and residual inert film. The result is a stellar old sand recovery rate of ≥90% and ignition loss ≤1.0%. This cutting-edge design synthesizes Qingdao Binhai Jincheng Company's boiling bed technology with Shengquan Group's airflow classification expertise.
3. Key technological innovations
Wear-resistant and shock-absorbing collaborative design
Our rubbing blades are crafted with tungsten carbide hard alloy, achieving a groundbreaking service life exceeding 8,000 hours, redefining durability standards.
Equipped with a spring-layered buffer structure, our bearing seat boasts a vibration transmission attenuation rate of over 60%, addressing traditional equipment challenges like sealing failure due to vibration.
Intelligent control and energy efficiency optimization
Precision meets adaptability as the lower grinding disc guide nut adjusts the 0.5-3mm gap, accommodating diverse sand types, such as alkaline phenolic resin sand, which requires a wider gap for optimal processing.
Experience unparalleled energy efficiency with our advanced power configuration! Dynamically tailored to match the output requirements, such as the impressive 30t/h model powered by an efficient 18.5kW system, this innovation reduces energy consumption by a remarkable 25% compared to similar equipment—ensuring cost savings and environmental benefits.
Seamlessly integrate with diverse sand types using our Composite Regeneration Compatibility. This versatile feature allows our system to adapt efficiently to a wide range of sand regeneration needs.
Revolutionize your sand regeneration process with our system's exceptional capability to handle a variety of old sands including furan resin sand, water glass sand, and alkaline phenolic resin sand. Especially adept at overcoming the resilient film characteristics of alkaline phenolic sand, our pioneering combination of high-temperature pre-baking (450-730ºC) paired with a specialized chemical release agent breaks through the limitations of conventional mechanical regeneration, offering unmatched performance and reliability.
