Product Description
Our state-of-the-art Green Sand Casting Old Sand Screen features a revolutionary design paradigm that integrates a large-end feeding and a small-end discharging mechanism, powered by the spindle's innovative tilting installation. This cutting-edge design significantly amplifies screening efficiency as materials cascade from an elevated point, ensuring exceptional crushing and screening performance at high speeds.
Crafted with meticulous precision, our long hole net utilizes cold-drawn stainless steel braided mesh, ensuring unmatched durability and longevity. Perfectly suited for processing hot and humid materials, this net's hexagonal tensioned design prevents breakage while offering remarkable rebound. The ease of screen replacement further minimizes downtime, enhancing operational efficacy.
Our system incorporates a robust ventilation setup at the air inlet, expertly cooling the sand while precisely managing the mud content. This meticulous process safeguards the integrity and enhances the quality of the reclaimed sand.
In the complex cycle of foundry sand treatment and regeneration, the swift cooling and precise screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are crucial for optimizing the reuse rate of molding sand. Our advanced inclined spindle screening machine delivers a comprehensive and high-efficiency sand treatment solution tailored for foundry workshops. Embracing innovative dynamic design, it offers refined high-temperature resilience, structure optimization, and an intelligent temperature control system. This exploration will unravel the dual advancements in screening efficiency and sand quality management, covering technical principles, process adaptability, energy efficiency, and industry application.
1. Technological innovation and core design breakthrough
Tackling industry challenges such as clogging and excessive wear in hot, wet sand screening, our equipment introduces groundbreaking technological advancements through dynamic optimization and innovative material selection:
Tilted spindle dynamic design:
Our strategically inclined spindle (15°-25°), coupled with a large end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min), facilitates a parabolic trajectory of sand particles (initial velocity 2-5m/s) across the screen. This setup ensures effective impact crushing and screening, achieving an impressive processing capacity of 20-80t/h, surpassing traditional horizontal screening machines by a staggering 40% in efficiency.
Double-center adjustment system: This innovative system ensures balanced vibration trajectory via a counterweight block (adjustable ±5kg), maintaining amplitude fluctuation rates below 5%. It enhances screening accuracy to an AFS particle size standard deviation of ±0.1mm, establishing new benchmarks in precision.
Cold-drawn stainless steel woven screen:
Manufactured from 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), enhancing tensile strength by 50% and offering a service life exceeding 8000 hours. This screen is expertly designed to endure high-temperature sand impact environments up to 300ºC.
Quick-release tension fixing system: Leveraging a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single operator can perform screen replacements in under 10 minutes, drastically reducing downtime by up to 70%.
2. Full-process integrated solution for foundry sand treatment
Our system seamlessly integrates into the complete sand treatment cycle, encompassing dropping, screening, cooling, and regeneration, to cultivate a smart, efficient sand treatment ecosystem.
High-temperature old sand pretreatment:
Directly connected to the vibrating sand dropping machine's outlet, the system efficiently processes old sand containing iron beans (≤20mm) and pouring and riser residues. The integrated magnetic separation module (1500Gs) boasts an impressive iron impurity removal efficiency of over 99%, tripling the screen's impact and wear resistance.
Featuring a sealed structure (leakage rate <3mg/m³), it seamlessly connects to a pulse dust collector, maintaining dust concentrations in the working area at below 5mg/m³, while keeping noise levels at a comfortable ≤78dB(A).
Precise sand quality control:
Discover the pinnacle of precision with our cutting-edge three-level screening system, crafted with intricate attention to detail. Offering multiple granularity levels at Φ5mm, Φ1mm, and Φ0.2mm, this system expertly grades regenerated sand, micro powder, and waste slag. It guarantees a remarkable sand particle uniformity, maintaining a CU value at a strikingly low ≤1.2. This meticulous grading process enhances the casting surface finish to an outstanding Ra6.3μm, ensuring superior quality and consistency in every application.
Unlock unparalleled efficiency with our screening system, which proudly boasts an exceptional >98% efficiency rate. The impurity content in the screened sand is impressively controlled to remain at a minimal <0.1%, dramatically improving resource optimization. This innovation leads to a substantial reduction in the need for new sand replenishment by an impressive 50%, allowing you to conserve resources while maintaining superior quality.
Our state-of-the-art equipment is designed for extraordinary performance, showcasing an Overall Equipment Efficiency (OEE) of a remarkable 93%. With a Mean Time Between Failures (MTBF) exceeding 15,000 hours, the equipment guarantees exceptional reliability and productivity. Experience consistent, high-quality output that ensures your operations run smoothly and efficiently.
