Product Description
Introducing our cutting-edge Green Sand Casting Old Sand Screen, meticulously engineered to elevate your screening processes to new heights. With a sophisticated large-end feeding and small-end discharging system, enabled by a uniquely tilted spindle design, this remarkable machine ensures exceptional efficiency. The cascading of materials from a higher vantage point ensures that both crushing and screening operations are executed with unparalleled precision and speed.
Crafted with the utmost precision, the long hole net is composed of cold-drawn stainless steel braided mesh, guaranteeing an exceptional lifespan. Perfectly suited for hot and humid material handling, this net boasts a hexagonal tensioned construction that resists breakage while offering outstanding rebound characteristics. Screen replacement is swift and seamless, ensuring operational continuity with minimal interruptions.
Our system harnesses the power of robust ventilation at the air inlet to adeptly cool the sand while meticulously managing mud content. This pivotal feature preserves the integrity and quality of the old sand, ensuring that your materials remain in pristine condition.
In the complex realm of foundry sand treatment and regeneration, the rapid cooling and precise screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are vital for maximizing molding sand reuse. Our innovative inclined spindle screening machine delivers an all-encompassing sand treatment solution for foundry environments. With revolutionary dynamic design, high-temperature resistant structural enhancements, and an intelligent temperature control system, this exploration highlights how our state-of-the-art equipment achieves groundbreaking advancements in screening efficiency and sand quality management. It addresses technical principles, process adaptability, energy efficiency, and diverse industry applications.
1. Unleashing Technological Innovation and Core Design Breakthroughs
Confronting industry obstacles such as clogging and high wear in hot, wet sand screening, our equipment introduces groundbreaking technological advancements via optimized dynamics and material innovation:
Innovative Tilted Spindle Dynamic Design:
Our strategically inclined spindle, set at a precise angle of 15°-25°, operates in harmony with a large-end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles traverse the screen along a parabolic path (initial velocity 2-5m/s), enabling effective impact crushing and screening. This results in an impressive processing capacity of 20-80t/h, surpassing traditional horizontal screening machine efficiency by 40%.
Double-Center Adjustment System: This ingenious system ensures balanced vibration trajectories 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, setting new standards in precision.
Premium Cold-Drawn Stainless Steel Woven Screen:
Engineered from high-grade 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). This design boosts tensile strength by 50% and offers a remarkable service life exceeding 8000 hours. The screen is built to endure high-temperature sand impact environments up to 300ºC.
Efficient Quick-Release Tension Fixing System: Using a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single operator can replace the screen in under 10 minutes, reducing downtime by up to 70%.
2. Comprehensive Full-Process Integrated Solution for Foundry Sand Treatment
Our system seamlessly integrates into the entire sand treatment cycle, covering processes of dropping, screening, cooling, and regeneration. This creates a smart, efficient sand treatment ecosystem that enhances productivity and quality.
High-Temperature Old Sand Pretreatment:
Directly connected to the outlet of the vibrating sand dropping machine, the system adeptly handles old sand containing iron beans (≤20mm) and pouring and riser residues. Featuring an integrated magnetic separation module (1500Gs), it achieves iron impurity removal efficiency of over 99%, tripling the screen's impact and wear resistance.
Boasting a closed structure (leakage rate <3mg/m³), it is linked to a pulse dust collector, maintaining dust concentrations in the working area at under 5mg/m³, and ensuring noise levels remain at a comfortable ≤78dB(A).
Meticulous Sand Quality Control:
Immerse yourself in the precision and sophistication of our cutting-edge three-tier screening system, expertly crafted to handle multiple granularity levels with Φ5mm, Φ1mm, and Φ0.2mm. This system is tailored to finesse regenerated sand, micro powder, and waste slag, ensuring remarkable uniformity with a CU value consistently at or below an impressive ≤1.2. This meticulous process elevates your casting surface's brilliance to a stunning Ra6.3μm.
Unlock unparalleled efficiency with our screening system, achieving a phenomenal >98% efficiency rate. The screened sand retains minimal impurity content at <0.1%, dramatically enhancing resource optimization. This innovation slashes the need for new sand replenishment by a noteworthy 50%, redefining operational excellence.
Our cutting-edge equipment is meticulously engineered for outstanding performance, boasting an Overall Equipment Efficiency (OEE) of 93%. With a remarkable Mean Time Between Failures (MTBF) exceeding 15,000 hours, you can trust in steadfast reliability and unrivaled productivity.
