Product Description
Our cutting-edge Green Sand Casting Old Sand Screen showcases an exceptional design with an innovative spindle tilting installation. This feature allows for a large end feeding and small end discharging system, enhancing screening efficiency. As materials cascade from a height, our system ensures unparalleled crushing and screening capabilities at rapid speeds.
Expertly engineered, the long hole net is constructed from cold-drawn stainless steel braided mesh, ensuring exceptional durability. Perfect for processing hot, humid materials, this net's hexagonal tensioned design prevents breakage while offering superior rebound. Easy screen replacement guarantees minimal operational downtime.
Our system utilizes powerful ventilation at the air inlet to efficiently cool the sand, all while precisely managing mud content. This meticulous process ensures the integrity and high quality of the old sand is preserved.
In the complex cycle of foundry sand treatment and regeneration, the swift cooling and meticulous screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are crucial for improving the reuse rate of molding sand. Our inclined spindle screening machine delivers an all-encompassing sand treatment solution for foundry workshops. Through its revolutionary dynamic design, it features high-temperature resistant structure optimization and an intelligent temperature control system. This exploration will uncover how this state-of-the-art equipment achieves dual advancements in screening efficiency and sand quality management by delving into its technical principles, process adaptability, energy efficiency, and industry applications.
1. Technological innovation and core design breakthrough
Our equipment addresses industry challenges such as clogging and high wear in hot, wet sand screening. We introduce technological advancements by optimizing dynamics and innovating materials:
Tilted spindle dynamic design:
Our spindle, strategically inclined at 15°-25°, works seamlessly with a large end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). Sand particles are propelled along a parabolic trajectory (initial velocity 2-5m/s) across the screen, achieving efficient impact crushing and screening. This results in an extraordinary processing capacity of 20-80t/h, surpassing the efficiency of conventional horizontal screening machines by 40%.
Double-center adjustment system: This innovative system maintains balanced vibration trajectory via a counterweight block (adjustable ±5kg), ensuring amplitude fluctuation rates below 5%. It refines screening accuracy to an AFS particle size standard deviation of ±0.1mm, setting new precision standards.
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) features a hexagonal honeycomb structure (35-60% opening rate), lifting tensile strength by 50% and delivering a service life surpassing 8000 hours. This screen is engineered to endure high-temperature sand impact environments up to 300ºC.
Quick-release tension fixing system: With a hydraulic tensioner (pressure 0.5-1.2MPa) and hexagonal locking module, screen replacements can be completed by a single operator in under 10 minutes, reducing downtime by up to 70%.
2. Full-process integrated solution for foundry sand treatment
Our system flawlessly integrates into the sand treatment cycle of dropping, screening, cooling, and regeneration. This creates a smart, efficient sand treatment ecosystem, revolutionizing the process.
High-temperature old sand pretreatment:
Directly connected to the outlet of the vibrating sand dropping machine, the system proficiently handles old sand with iron beans (≤20mm) and pouring and riser residues. The included magnetic separation module (1500Gs) excels in iron impurity removal with over 99% efficiency, tripling the screen's impact and wear resistance.
Featuring a closed structure (leakage rate <3mg/m³), it seamlessly connects to a pulse dust collector, keeping dust levels in the working area under 5mg/m³, and maintaining noise levels at a comfortable ≤78dB(A).
Precise sand quality control:
Delve into the precision and excellence of our cutting-edge three-level screening system, expertly crafted with a detailed approach to granularity. Featuring precise levels at Φ5mm, Φ1mm, and Φ0.2mm, it offers unparalleled grading for regenerated sand, micro powder, and waste slag. By maintaining a CU value at an outstanding ≤1.2, we ensure an exceptional uniformity in sand particles, elevating your casting surface finish to an extraordinary Ra6.3μm. This commitment to precision amplifies the quality and consistency of your casting outcomes.
Elevate your production efficiency with our superior screening system, delivering an impressive >98% efficiency rate. The meticulously filtered sand maintains a remarkable impurity content of <0.1%, dramatically optimizing resource allocation. This translates into a significant reduction in the need for new sand replenishment by an extraordinary 50%, enhancing both cost-effectiveness and environmental sustainability.
Harness the power of our state-of-the-art equipment, meticulously engineered for outstanding performance. With an impressive Overall Equipment Efficiency (OEE) of 93%, it guarantees superior reliability and productivity. A remarkable Mean Time Between Failures (MTBF) exceeding 15,000 hours underscores its durability and dependability, ensuring your operations run smoothly and efficiently.
