Product Description
Amplifying the screening prowess, our state-of-the-art Tailored Green Sand Casting Old Sand Screen adopts a pioneering large end feeding and small end discharging design, enhanced by a spindle tilting installation. This dynamic configuration harnesses high-speed operation, enabling materials to gracefully descend from elevated vantage points, ensuring efficient crushing and meticulous screening.
Engineered for longevity, our long hole net utilizes a cold-drawn stainless steel braided mesh, perfectly suited for challenging hot and humid environments. Uniquely designed with a hexagonal structure that interlocks, the screen resists breakage, boasts an exceptional rebound effect, and can be effortlessly replaced, offering unparalleled durability and ease of maintenance.
Harnessing robust ventilation technology, our air inlet system cools the sand while expertly managing the mud content of the old sand. This proactive feature ensures a refined sand quality, enhancing the overall efficiency of the casting process.
In the intricate journey of foundry sand treatment and regeneration, our cutting-edge inclined spindle screening machine stands as a beacon of innovation, designed to transform the core processes of rapid cooling and precision screening of high-temperature wet sand (temperatures ranging from 80-150ºC with 3-8% moisture content). By integrating advanced dynamic design, a high-temperature resistant structure, and an intelligent temperature control system, our solution paves the way for a revolutionary leap in screening efficiency and sand quality management. This comprehensive analysis delves into the technological principles, process adaptability, energy efficiency optimization, and industry application, showcasing the dual breakthroughs achieved in foundry operations.
1. Technological Innovation and Core Design Breakthrough
Addressing the industry's formidable challenges of clogging and wear when screening hot and wet sand, our equipment triumphs through dynamic optimization and material innovation, achieving remarkable technological advancements:
Tilted Spindle Dynamic Design:
Our innovative spindle, set at a 15°-25° inclination, combines a generous large end feed port (Φ600-1200mm) with a high-performance vibration motor (speed 900-1500r/min). Sand particles launch onto the screen following a parabolic trajectory (initial velocity 2-5m/s), masterfully achieving dual-impact crushing and screening. This advanced design elevates processing capacity to 20-80t/h, outperforming conventional horizontal screening machines by a striking 40%.
Double-Center Adjustment System: Through an ingenious counterweight block (adjustable ±5kg), the vibration trajectory is dynamically balanced, ensuring an amplitude fluctuation rate of <5%. With screening accuracy (AFS particle size standard deviation) honed to ±0.1mm, precision is redefined.
Cold-Drawn Stainless Steel Woven Screen:
Crafted from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long hole mesh is woven into a robust hexagonal honeycomb structure (opening rate 35-60%). This design amplifies the screen's tensile strength by 50%, ensuring a service life > 8000 hours, adeptly managing 300ºC high-temperature sand impact environments with resilience.
Quick-Release Tension Fixing System: Streamlining maintenance, the hydraulic tensioner (pressure 0.5-1.2MPa) and hexagonal locking module expedite screen replacement to under 10 minutes, reducing downtime by an impressive 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
Seamlessly integrating into the comprehensive process chain of sand dropping, screening, cooling, and regeneration, our equipment forms the cornerstone of an intelligent sand treatment ecosystem, redefining foundry efficiency and sustainability:
High-Temperature Old Sand Pretreatment:
Directly aligning with the vibrating sand dropping machine's outlet, our system adeptly processes old sand laden with iron beans (≤20mm) and casting residues. Equipped with a magnetic separation module (1500Gs), it boasts an iron impurity separation efficiency exceeding 99%, while tripling the impact and wear resistance of the screen.
Enclosed within a secure structure (leakage rate <3mg/m³) and linked to a pulse dust collector, our system maintains dust concentrations in the working area at <5mg/m³, with noise levels contained to ≤78dB(A), fostering a safer, quieter work environment.
Precise Sand Quality Control:
Our innovative three-level screening system, meticulously engineered to provide optimal performance, is designed with precision gradations (Φ5mm/Φ1mm/Φ0.2mm). This advanced system meticulously classifies regenerated sand, micro powder, and residual waste slag with unparalleled accuracy. The superior uniformity of sand particles, boasting a CU value of ≤1.2, is instrumental in achieving an exceptionally smooth casting surface with a remarkable roughness of Ra6.3μm. This ensures that your castings are not only flawless in appearance but also impeccable in quality.
Experience unprecedented efficiency with our state-of-the-art screening technology, achieving an impressive screening efficiency of over 98%. The screened sand is exceptionally pure, containing impurities of less than 0.1%. This remarkable purification process significantly reduces the need for new sand replenishment by an astounding 50%, providing both economic and environmental benefits for our clients.
Our cutting-edge equipment boasts an exceptional Overall Equipment Efficiency (OEE) of 93%, setting new standards in operational excellence. With a Mean Time Between Failures (MTBF) exceeding 15,000 hours, our machinery promises reliability and longevity, ensuring continuous and seamless operations that significantly enhance productivity and reduce downtime.
