Product Description
Experience an evolution in screening efficiency with our innovative design featuring large end feeding and small end discharging through a uniquely tilted spindle installation. This remarkable setup enhances screening capabilities at high speeds, allowing materials to effortlessly cascade from elevated points, achieving efficient crushing and superior screening all in one seamless process.
Our sieve showcases advanced technology with a cold-drawn stainless steel braided net, engineered for durability and longevity, especially adept for handling hot and humid materials. Its hexagonal outer structure ensures a tensioned and secure fit, providing exceptional resilience against breaking while offering a superior rebound effect. Plus, it is designed for quick and easy replacement, minimizing downtime.
Our system incorporates robust ventilation at the air inlet, effectively cooling the sand and managing the mud content in reconditioned sand, ensuring optimal quality standards are maintained.
In the realm of foundry sand treatment and regeneration, mastering the rapid cooling and precise screening of high-temperature wet sand is pivotal for enhancing the reuse rate of molding sand. Our uniquely inclined spindle screening machine offers a comprehensive, one-stop solution for foundry workshops. By integrating innovative dynamic designs, a high-temperature resistant structure, and an intelligent temperature control system, this equipment champions a dual leap in screening efficiency and sand quality management. This analysis delves into the technical principles, process adaptability, energy efficiency optimization, and industry applications that underpin this groundbreaking advancement.
1. Technological innovation and core design breakthrough
Addressing the industry's core challenges of screen clogging and wear in hot, wet sand environments, our equipment has pushed the boundaries of technology with dynamic optimizations and pioneering material innovation:
Tilted spindle dynamic design:
Strategically inclined at 15°-25°, the spindle integrates seamlessly with a generously sized feed port (Φ600-1200mm) and a high-performance vibration motor (speed 900-1500r/min). This synergy propels sand particles along a parabolic path (initial velocity 2-5m/s), combining impact crushing with effective screening. With a processing capacity of 20-80t/h, this efficiency surpasses traditional horizontal screening machines by 40%.
Double-center adjustment system: Our system features a precision-engineered counterweight block (adjustable ±5kg) ensuring a dynamically balanced vibration trajectory. This system maintains an amplitude fluctuation rate of <5%, elevating screening accuracy to an AFS particle size standard deviation of ±0.1mm, thus optimizing performance.
Cold-drawn stainless steel woven screen:
Crafted from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), this screen features a long hole mesh (aperture Φ0.2-5mm) arranged in a hexagonal honeycomb structure (opening rate 35-60%). This design enhances the screen's tensile strength by 50%, ensuring a service life exceeding 8000 hours, perfectly suited for a 300ºC high-temperature sand impact environment.
Quick-release tension fixing system: With a sophisticated hydraulic tensioner (pressure 0.5-1.2MPa) and hexagonal locking module, a single person can execute a screen replacement in under 10 minutes, slashing downtime by an impressive 70%.
2. Full-process integrated solution for foundry sand treatment
This state-of-the-art equipment integrates seamlessly into the sand treatment process chain, including sand dropping, screening, cooling, and regeneration, fostering an intelligent sand treatment ecosystem poised to transform the industry.
High-temperature old sand pretreatment:
Directly interfacing with the vibrating sand dropping machine's outlet, our system efficiently processes old sand containing iron beans (≤20mm) and pouring and riser residues. The magnetic separation module (1500Gs) achieves >99% efficiency in iron impurity separation, while boosting the screen's impact and wear resistance threefold.
A closed structure (leakage rate <3mg/m³) is meticulously connected to a pulse dust collector, ensuring the dust concentration within the working area remains <5mg/m³, while maintaining noise levels at a tranquil ≤78dB(A).
Precise sand quality control:
Our advanced three-level screening system, featuring precision grading sizes of Φ5mm, Φ1mm, and Φ0.2mm, meticulously classifies regenerated sand, micro powder, and waste slag. This cutting-edge technology ensures that the sand particle uniformity, or CU value, remains an impressive ≤1.2, dramatically enhancing the casting surface smoothness to achieve an exceptional roughness of Ra6.3μm.
Boasting a remarkable screening efficiency of over 98%, our system ensures that the impurity content of screened sand is kept to an astonishingly low <0.1%. This outstanding performance significantly curtails the need for new sand replenishment by an impressive 50%, promoting both cost savings and environmental sustainability.
Experience unrivaled operational excellence with our equipment, where the Overall Equipment Efficiency (OEE) soars to an impressive 93%. With a Mean Time Between Failures (MTBF) exceeding 15,000 hours, our product guarantees reliable, continuous operation, reducing downtime and enhancing productivity on your manufacturing floor.
