Product Description
Immerse yourself in the pinnacle of efficiency with our state-of-the-art Green Sand Casting Old Sand Screen. This marvel of engineering boasts a groundbreaking dynamic design with a larger-than-life end feeding coupled with a sleek small end discharging mechanism, all thanks to the novel spindle tilting installation. Elevate your screening endeavors as this advanced feature propels materials from a higher vantage point, enabling unparalleled crushing and screening prowess at exhilarating speeds.
Precision-crafted to perfection, our long hole net, meticulously woven from cold-drawn stainless steel braided mesh, ensures unmatched durability and longevity. This net excels in handling hot and humid materials with its ingeniously designed hexagonal tensioned structure, effectively safeguarding against breakage while offering remarkable rebound properties. Effortless screen replacement guarantees minimal downtime, keeping your operations running seamlessly.
Harnessing the power of robust ventilation at the air inlet, our cutting-edge system not only cools the sand effectively but also meticulously regulates the mud content. This intricate process preserves the integrity and superior quality of the old sand, ensuring optimal performance throughout.
In the realm of foundry sand treatment and regeneration, rapid cooling and meticulous screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are pivotal processes. Our inclined spindle screening machine emerges as a comprehensive solution, tailored for foundry workshops. With an innovative dynamic design, this machine exemplifies high-temperature resistant structure optimization and intelligent temperature control. Join us as we explore how this cutting-edge equipment achieves monumental advancements in screening efficiency and sand quality management, from its technical principles and process adaptability to energy efficiency and industry-specific applications.
1. Technological Innovation and Core Design Breakthrough
Confronting industry challenges like clogging and high wear in hot, wet sand screening, our equipment stands at the forefront of technological advancements. By optimizing dynamics and pioneering material innovations, we redefine efficiency:
Tilted Spindle Dynamic Design:
Ingeniously inclined at 15°-25°, our spindle collaborates seamlessly with a generous end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles gracefully follow a parabolic path (initial velocity 2-5m/s) across the screen, achieving effective impact crushing and screening. This translates to a formidable processing capacity of 20-80t/h, outperforming traditional horizontal screeners by a staggering 40%.
Double-Center Adjustment System: A revolution in precision, this system utilizes a counterweight block (adjustable ±5kg) to ensure the vibration trajectory remains impeccably balanced, with amplitude fluctuation rates below 5%. It achieves screening accuracy to an AFS particle size standard deviation of ±0.1mm, setting unparalleled precision benchmarks.
Cold-Drawn Stainless Steel Woven Screen:
Crafted from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long hole mesh, with an aperture range of Φ0.2-5mm, features a hexagonal honeycomb structure (35-60% opening rate). This design enhances tensile strength by 50%, offering an impressive service life that exceeds 8000 hours. It's engineered to withstand high-temperature sand impact environments of up to 300ºC.
Quick-Release Tension Fixing System: Our system, utilizing a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, empowers a single operator to achieve screen replacement in under 10 minutes, dramatically reducing downtime by up to 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
Our solution seamlessly integrates into every stage of the sand treatment cycle: from dropping and screening to cooling and regeneration, creating a smart, efficient ecosystem for sand treatment.
High-Temperature Old Sand Pretreatment:
Linked directly to the outlet of the vibrating sand dropping machine, our system excels in managing old sand mixed with iron beans (≤20mm) and pouring and riser residues. The integrated magnetic separation module (1500Gs) achieves an iron impurity removal efficiency exceeding 99%, tripling the screen's impact and wear resistance.
With a closed structure (leakage rate <3mg/m³), it seamlessly connects to a pulse dust collector. This maintains dust concentrations in the working area at a safe level below 5mg/m³ and keeps noise levels comfortably at or below ≤78dB(A).
Precise sand quality control:
Experience the pinnacle of precision with our cutting-edge three-level screening system. This marvel of engineering offers meticulous sand grading with granular precision at Φ5mm, Φ1mm, and Φ0.2mm. It expertly classifies regenerated sand, micro powder, and waste slag, ensuring sand particle uniformity with a CU value of an impressive ≤1.2. The result? An unparalleled casting surface finish at an extraordinary Ra6.3μm.
Elevate your operational efficiency with our superior screening system, boasting an exceptional >98% efficiency rate. The impurity content in the screened sand is reduced to an astounding <0.1%, dramatically optimizing resource utilization. This significant reduction in impurity levels slashes the need for new sand replenishment by a remarkable 50%, offering both economic and environmental benefits.
Our state-of-the-art equipment redefines performance standards with an exceptional Overall Equipment Efficiency (OEE) of 93%. With a Mean Time Between Failures (MTBF) exceeding 15,000 hours, you can rely on its unmatched reliability and productivity, setting a new benchmark in the industry.
