Product Description
Introducing our pioneering Green Sand Casting Old Sand Screen, a marvel of engineering that masterfully combines a dynamic design with a sophisticated large end feeding and small end discharging system. Thanks to its innovative spindle tilting installation, this masterpiece enhances screening efficiency by allowing materials to cascade from lofty heights, ensuring unparalleled crushing and screening capabilities at exceptional speeds.
Our precision-crafted long hole net, made of cold-drawn stainless steel braided mesh, is built for unmatched durability. Perfectly suited for hot, humid materials, it boasts a hexagonal tensioned design that fortifies against breakage and delivers superior rebound. The ease of replacing the screen ensures minimal downtime, promising an effortless maintenance experience.
Our system ingeniously employs robust ventilation at the air inlet, not only to cool the sand effectively but also to astutely manage mud content, thereby preserving the integrity and premium quality of the old sand.
In the complex realm of foundry sand treatment and regeneration, our advanced approach to the rapid cooling and meticulous screening of high-temperature wet sand (80-150ºC, 3-8% moisture) is pivotal in elevating the reuse rate of molding sand. The inclined spindle screening machine provides a holistic sand treatment solution tailored for foundry workshops. Through revolutionary dynamic design, it features high-temperature resistant structure optimization and a sophisticated intelligent temperature control system. This exploration unveils how this cutting-edge equipment achieves unmatched advancements in screening efficiency and sand quality management across technical principles, process adaptability, energy efficiency, and industry application.
1. Technological innovation and core design breakthrough
Our equipment overcomes industry challenges such as clogging and high wear in hot, wet sand screening by introducing groundbreaking technological advancements through dynamic optimization and material innovation:
Tilted spindle dynamic design:
Expertly engineered, our spindle is strategically inclined at 15°-25°, perfectly complementing a large end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles traverse a parabolic trajectory (initial velocity 2-5m/s) across the screen, achieving remarkable impact crushing and screening. With a processing capacity of 20-80t/h, it surpasses traditional horizontal screening machines' efficiency by a significant margin of 40%.
Double-center adjustment system: This innovative system ensures that the vibration trajectory stays impeccably balanced via a counterweight block (adjustable ±5kg), maintaining amplitude fluctuation rates below 5%. This system elevates screening accuracy to an AFS particle size standard deviation of ±0.1mm, setting new industry precision benchmarks.
Cold-drawn stainless steel woven screen:
Constructed from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), this long hole mesh (aperture Φ0.2-5mm) showcases a hexagonal honeycomb structure (35-60% opening rate), enhancing tensile strength by 50% and delivering a service life exceeding 8000 hours. It is designed to withstand high-temperature sand impact environments up to 300ºC effortlessly.
Quick-release tension fixing system: Our system employs a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, enabling a single operator to accomplish screen replacement in under 10 minutes, drastically reducing downtime by up to 70%.
2. Full-process integrated solution for foundry sand treatment
Our groundbreaking system seamlessly integrates into the complete sand treatment cycle of dropping, screening, cooling, and regeneration, creating a smart and efficient sand treatment ecosystem that sets new industry standards.
High-temperature old sand pretreatment:
Ingeniously linked directly to the outlet of the vibrating sand dropping machine, the system proficiently handles old sand with iron beans (≤20mm) and pouring and riser residues. Featuring an advanced magnetic separation module (1500Gs), it achieves an iron impurity removal efficiency exceeding 99%, tripling the screen's impact and wear resistance for unparalleled performance.
Boasting a closed structure (leakage rate <3mg/m³), the system connects to a pulse dust collector, maintaining dust concentrations in the working area under 5mg/m³, while ensuring noise levels remain comfortably at ≤78dB(A).
Unparalleled and Precise Sand Quality Control:
Immerse yourself in the precision of our cutting-edge three-level screening system, expertly crafted to deliver multiple granularity levels at Φ5mm, Φ1mm, and Φ0.2mm. This innovative design ensures the flawless grading of regenerated sand, micro powder, and waste slag. Achieve an exceptional uniformity in sand particles with a CU value maintained at an impressive ≤1.2, thereby enhancing the casting surface finish to a truly remarkable Ra6.3μm.
Unlock outstanding efficiency with our premier screening system, boasting an extraordinary >98% efficiency rate. The screened sand is maintained with impurity content at an impressive <0.1%, paving the way for significant resource optimization by reducing the necessity for new sand replenishment by an incredible 50%.
Experience exceptional performance with our state-of-the-art equipment, meticulously designed to deliver a remarkable Overall Equipment Efficiency (OEE) of 93%. With a Mean Time Between Failures (MTBF) exceeding 15,000 hours, you can be confident in the unrivaled reliability and productivity we offer.
