Product Description
Introducing our state-of-the-art Green Sand Casting Old Sand Screen, an epitome of engineering excellence! Featuring a pioneering dynamic design, this masterpiece incorporates a large end feeding and a small end discharging system, made possible by its ingeniously tilted spindle installation. This engineering marvel propels materials from a high vantage point, optimizing screening efficiency, while delivering unparalleled crushing and screening capabilities at elevated speed levels.
Meticulously crafted, the long hole net is composed of cold-drawn stainless steel braided mesh, ensuring unmatched durability. Perfect for tackling hot and humid materials, this net's hexagonal tensioned design not only inhibits breakage but also provides remarkable rebound. With an easy-to-replace screen system, downtime is minimized, enhancing productivity.
Our system champions robust ventilation at the air inlet, expertly cooling the sand and meticulously managing mud content. This ensures the preservation of the old sand's integrity and quality, a testament to our commitment to excellence.
Within the elaborate foundry sand treatment and regeneration cycle, the swift cooling and scrupulous screening of high-temperature wet sand (ranging from 80-150ºC, with a moisture content of 3-8%) are crucial. These processes significantly boost the reuse rate of molding sand. Our inclined spindle screening machine stands as a formidable ally for foundry workshops, offering a complete sand treatment solution. With innovative dynamic design, it features high-temperature resistant structure optimization and an intelligent temperature control system. This exploration unveils how this cutting-edge equipment spearheads dual advancements in screening efficiency and sand quality management, across multiple dimensions such as technical principles, process adaptability, energy efficiency, and industry applications.
1. Technological innovation and core design breakthrough
Tackling industry challenges like clogging and high wear during hot, wet sand screening, our equipment ushers in new technological advancements by refining dynamics and materials innovation:
Tilted spindle dynamic design:
Our strategically inclined spindle, positioned at an optimal angle of 15°-25°, harmonizes with a large end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles traverse a parabolic trajectory (initial velocity of 2-5m/s) across the screen, effectuating effective impact crushing and screening. The result? A remarkable processing capacity of 20-80t/h, which surpasses traditional horizontal screening machine efficiency by a whopping 40%!
Double-center adjustment system: This revolutionary system maintains a balanced vibration trajectory with a counterweight block (adjustable ±5kg), ensuring amplitude fluctuation rates remain below 5%. It elevates screening accuracy to an unprecedented AFS particle size standard deviation of ±0.1mm, setting new precision benchmarks in the industry.
Cold-drawn stainless steel woven screen:
Composed of 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), this long hole mesh (aperture Φ0.2-5mm) features a hexagonal honeycomb structure (35-60% opening rate), boosting tensile strength by 50% and offering an extraordinary service life exceeding 8000 hours. This screen is adept at withstanding high-temperature sand impact environments, up to an impressive 300ºC.
Quick-release tension fixing system: Through the use of a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single operator is empowered to complete screen replacement in under 10 minutes, slashing downtime by a staggering 70%.
2. Full-process integrated solution for foundry sand treatment
Our system seamlessly incorporates into the complete sand treatment cycle, including dropping, screening, cooling, and regeneration processes, creating a sophisticated, efficient sand treatment ecosystem that sets new industry standards.
High-temperature old sand pretreatment:
Seamlessly connected to the vibrating sand dropping machine outlet, the system expertly handles old sand with iron beans (≤20mm) and residual pouring and riser materials. The integrated magnetic separation module (1500Gs) achieves an iron impurity removal efficiency surpassing 99%, exponentially enhancing the screen's impact and wear resistance.
Boasting a closed structure (leakage rate <3mg/m³), it connects effortlessly to a pulse dust collector, maintaining dust concentrations in the workspace at under 5mg/m³, all while keeping noise levels to a pleasant ≤78dB(A).
Precise sand quality control:
Experience the impeccable precision of our cutting-edge three-level screening system, masterfully crafted to handle a variety of granularity levels at Φ5mm, Φ1mm, and Φ0.2mm. This system is designed to expertly grade regenerated sand, micro powder, and waste slag, ensuring sand particle uniformity with a CU value impressively maintained at ≤1.2. This meticulous process elevates the casting surface finish to an extraordinary Ra6.3μm, setting a new standard in the industry.
Achieve unparalleled efficiency with our screening system, showcasing an extraordinary >98% efficiency rate. The impurity content of the screened sand is remarkably controlled at <0.1%, allowing for significant resource optimization. This leads to a dramatic 50% reduction in the need for new sand replenishment, marking a substantial advancement in sustainable casting operations.
Our cutting-edge equipment is engineered for superior performance, demonstrated by an impressive Overall Equipment Efficiency (OEE) of 93%. With a Mean Time Between Failures (MTBF) that exceeds an incredible 15,000 hours, our system ensures unmatched reliability and productivity, cementing its status as a leader in innovation and efficiency.
