Product Description
Experience unparalleled efficiency with our advanced Green Sand Casting Old Sand Screen. Engineered to perfection, it features a dynamic design with a large end feeding and a small end discharging mechanism, thanks to its innovative spindle tilting installation. This cutting-edge feature maximizes screening efficiency, allowing materials to cascade from a higher point, ensuring exceptional crushing and screening capabilities at remarkable speeds.
Meticulously crafted, the long hole net is constructed from cold-drawn stainless steel braided mesh, ensuring exceptional durability and longevity. Designed to handle hot and humid materials effortlessly, this net features a hexagonal tensioned design to prevent breakage and provide outstanding rebound, making screen replacement swift and minimizing downtime.
Our system, with robust ventilation at the air inlet, effectively cools the sand while meticulously managing the mud content, safeguarding the integrity and quality of the old sand.
In the complex foundry sand treatment and regeneration cycle, the rapid cooling and meticulous screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are vital for enhancing the reuse rate of molding sand. Our inclined spindle screening machine offers an all-encompassing sand treatment solution tailored for foundry workshops. With pioneering dynamic design, it features high-temperature resistant structure optimization and a sophisticated temperature control system. This exploration delves into how this cutting-edge equipment achieves dual advancements in screening efficiency and sand quality management, assessed through technical principles, process adaptability, energy efficiency, and industry application.
1. Technological innovation and core design breakthrough
Overcoming industry challenges such as clogging and high wear in hot, wet sand screening, our equipment introduces groundbreaking technological advancements by optimizing dynamics and innovating materials:
Tilted spindle dynamic design:
Our strategically inclined spindle, set at a precise angle of 15°-25°, works seamlessly with a large end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles are directed in a parabolic trajectory (initial velocity 2-5m/s) across the screen, ensuring effective impact crushing and screening. This results in an astounding processing capacity of 20-80t/h, surpassing the efficiency of traditional horizontal screening machines by 40%.
Double-center adjustment system: This innovative system ensures the vibration trajectory remains perfectly balanced through a counterweight block (adjustable ±5kg), maintaining amplitude fluctuation rates below 5%. It enhances screening precision to an AFS particle size standard deviation of ±0.1mm, setting unprecedented precision standards.
Cold-drawn stainless steel woven screen:
Crafted from premium 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), significantly enhancing tensile strength by 50% and offering a service life exceeding 8000 hours. This screen is engineered to withstand high-temperature sand impact environments up to 300ºC.
Quick-release tension fixing system: Featuring a sophisticated hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single operator can complete screen replacement in under 10 minutes, drastically reducing downtime by up to 70%.
2. Full-process integrated solution for foundry sand treatment
Our system effortlessly integrates into the complete sand treatment cycle of dropping, screening, cooling, and regeneration, creating a smart and efficient sand treatment ecosystem.
High-temperature old sand pretreatment:
Directly linked to the outlet of the vibrating sand dropping machine, the system expertly handles old sand with iron beans (≤20mm) and pouring and riser residues. The integrated magnetic separation module (1500Gs) offers an iron impurity removal efficiency exceeding 99%, tripling the screen's impact and wear resistance.
Featuring a closed structure (leakage rate <3mg/m³), it connects seamlessly to a pulse dust collector, maintaining dust concentrations in the working area at under 5mg/m³, and keeps noise levels at a comfortable ≤78dB(A).
Precise sand quality control:
Discover the unparalleled precision of our cutting-edge three-level screening system, expertly crafted to handle specific granularity levels of Φ5mm, Φ1mm, and Φ0.2mm. This sophisticated design impeccably grades regenerated sand, micro powder, and waste slag, ensuring a sand particle uniformity that boasts a CU value of an extraordinary ≤1.2. Elevate your casting surface finish to a superior Ra6.3μm with this meticulously engineered solution.
Unlock exceptional efficiency with our state-of-the-art screening system, achieving an extraordinary >98% efficiency rate. The sand's impurity content is expertly controlled to stay below an impressive <0.1%, dramatically enhancing resource optimization. Experience a revolutionary reduction in new sand replenishment needs by an incredible 50%, driving sustainability and cost-effectiveness.
Our cutting-edge equipment is meticulously engineered to deliver outstanding performance, showcasing an Overall Equipment Efficiency (OEE) of 93%. With a Mean Time Between Failures (MTBF) exceeding an impressive 15,000 hours, you can count on unparalleled reliability and productivity to meet your operational demands with confidence.
