Product Description
Introducing the future of sand screening innovation: the Customized Green Sand Casting Old Sand Screen by Qingdao Sanzhuji Technology Co., Ltd. Boasting a state-of-the-art large-end feeding and small-end discharging system with spindle tilting installation, this groundbreaking design dramatically elevates screening efficacy. Its high-speed operation allows materials to flow seamlessly from great heights, optimizing both crushing and screening processes for unparalleled performance and efficiency.
Built to withstand the test of time, this robust product features a cold-drawn stainless steel braided net, designed to thrive in hot and humid environments. The meticulously crafted hexagon exterior ensures a tight interlock, preventing screen breakage while delivering a robust rebound effect. Easy replacement and exceptional longevity make it an ideal choice for those seeking durability and unwavering functionality.
Our pioneering system is equipped with powerful ventilation at the air inlet, adeptly cooling the sand and managing the mud content within the old sand. This precise control system not only improves the sand's quality but also assures that it aligns with the pinnacle of industry standards, setting a new benchmark for excellence.
In the relentless pursuit of premier sand quality, our foundry sand treatment and regeneration process stand as the cornerstone for rapid cooling and precise screening of high-temperature wet sand (80-150ºC, moisture 3-8%). The inclined spindle screening machine offers a holistic sand treatment solution with its innovative design, heat-resistant structure, and smart temperature control system. This comprehensive exploration reveals the dual advancements in screening efficiency and sand quality management, delving into technical principles, process adaptability, energy efficiency, and industry applications that redefine performance and dependability.
1. Technological innovation and core design breakthrough
Conquering the formidable challenges of clogging and wear seen in hot, wet sand screening, our equipment rises above with dynamic optimization and material innovation, setting unprecedented standards for performance and durability.
Tilted spindle dynamic design:
Featuring an ingenious spindle inclination of 15°-25°, coupled with expansive end feed ports (Φ600-1200mm) and high-speed vibration motors (900-1500r/min), the system drives sand particles along a parabolic path (initial speed 2-5m/s). This dynamic configuration facilitates synchronous impact crushing and screening, achieving processing capacities of 20-80t/h—a striking 40% improvement over conventional horizontal screens.
Double-center adjustment system: Our precision-tuned counterweight blocks (adjustable ±5kg) ensure dynamic balance of vibration trajectories, maintaining an amplitude fluctuation rate of <5% and elevating screening precision to an outstanding ±0.1mm AFS particle size standard deviation.
Cold-drawn stainless steel woven screen:
Engineered with high-grade 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long-hole mesh (aperture Φ0.2-5mm) features a hexagonal honeycomb formation (opening rate 35-60%), enhancing tensile strength by 50% and ensuring a service life surpassing 8000 hours—perfectly equipped for 300ºC high-temperature sand impact scenarios.
Quick-release tension fixing system: Our advanced hydraulic tensioner (pressure 0.5-1.2MPa) paired with a hexagonal locking module allows a single operator to change screens in under 10 minutes, reducing downtime by a remarkable 70%.
2. Full-process integrated solution for foundry sand treatment
Seamlessly woven into the sand treatment process chain—from sand dropping through to screening, cooling, and regeneration—our equipment creates an intelligent ecosystem that maximizes both efficiency and quality.
High-temperature old sand pretreatment:
By directly interfacing with the vibrating sand dropping machine outlet, our system proficiently handles old sand containing iron beans (≤20mm) and riser residues. The integrated magnetic separation module (1500Gs) ensures exceptional iron impurity isolation, achieving >99% separation efficiency and tripling the impact and wear resistance of the screen.
Encased within a leak-proof architecture (leakage rate <3mg/m³) linked to a pulse dust collector, we uphold a dust-free environment with concentrations <5mg/m³ and noise levels ≤78dB(A), creating a safe and efficient workspace.
Precise sand quality control:
Our state-of-the-art, three-level screening system is truly a marvel of precision engineering, boasting meticulous grading at Φ5mm, Φ1mm, and Φ0.2mm. This sophisticated mechanism flawlessly classifies regenerated sand, micro powder, and waste slag. Its cutting-edge grading process ensures an unparalleled sand particle uniformity (CU value) of ≤1.2, elevating the casting surface finish to an extraordinary level with a roughness that reaches an astounding Ra6.3μm. This is precision and perfection combined to deliver excellence in every grain.
Our system is engineered for peak performance with an astonishing screening efficiency that soars beyond 98%, ensuring that the impurity content in the screened sand is impressively maintained under 0.1%. This incredible level of efficiency slashes the need for new sand replenishment by an impressive 50%, thus optimizing resource utilization and pushing cost efficiency to new heights. It's a breakthrough in sustainable and economical production.
Boasting an exceptional Overall Equipment Efficiency (OEE) level of 93%, our system delivers unparalleled reliability. With a Mean Time Between Failures (MTBF) that surpasses 15,000 hours, it ensures sustained operation, free from interruptions, and sets a new benchmark in equipment performance. This system is the epitome of durability and high-caliber functionality, designed to keep your operations running smoothly and efficiently.
