Product Description
Embrace a revolution in efficiency with our advanced screening technology, meticulously designed to maximize throughput. Featuring an innovative large-end feeding and small-end discharging system with a strategically tilted spindle, our machine ensures superior screening capabilities. The high-velocity material flow optimizes both crushing and screening processes, achieving unparalleled results.
Crafted with precision, our long hole net is engineered from premium cold-drawn stainless steel braided mesh, ensuring a robust and enduring service life. Perfectly suited for challenging hot and humid material environments, the hexagon design ensures tension and stability, offering a resilient surface with an enviable rebound effect. The screen's ingenious design allows for effortless replacement, maximizing operational efficiency.
Harness the power of advanced ventilation technology at the air inlet, meticulously designed to efficiently cool sand while precisely controlling the mud content in recycled sand. This ensures optimal material conditions for further processing.
In the intricate process of foundry sand treatment and regeneration, the rapid cooling paired with precise screening of high-temperature, moisture-laden sand (80-150ºC with 3-8% moisture) stands at the forefront of enhancing reuse rates for molding sand. Our inclined spindle screening machine embodies a comprehensive sand treatment solution tailored for foundry operations. With cutting-edge dynamic design, a structure optimized for high temperatures, and an intelligent temperature control system, this article delves into the dual advancements achieved in screening efficiency and sand quality management, evaluated through technical principles, process adaptability, energy efficiency optimization, and industry applications.
1. Technological innovation and core design breakthrough
Addressing the pivotal industry challenges of screen clogging and wear in the screening of hot, moist sand, our equipment showcases remarkable technological advancements achieved through dynamic design optimization and material breakthroughs:
Tilted spindle dynamic design:
Our spindle installation boasts a strategic inclination of 15°-25°, seamlessly working with a large-end feed port (Φ600-1200mm) and a high-performance vibration motor (speed 900-1500r/min). Delivering sand particles onto the screen in a parabolic trajectory at speeds of 2-5m/s, this system achieves simultaneous impact, crushing, and screening. With a processing capacity of 20-80t/h, efficiency surpasses traditional horizontal screening machines by 40%.
Double-center adjustment system: By employing a counterweight block (adjustable by ±5kg), the vibration trajectory is precisely balanced, maintaining amplitude fluctuations below 5% and enhancing screening accuracy to a remarkable ±0.1mm in accordance with the AFS particle size standard deviation.
Cold-drawn stainless steel woven screen:
Utilizing 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long hole mesh (aperture Φ0.2-5mm) is expertly crafted into a hexagonal honeycomb structure. With an opening rate of 35-60%, this design amplifies the screen's tensile strength by 50%, ensuring a service life exceeding 8000 hours, even in extreme 300ºC sand impact environments.
Quick-release tension fixing system: With our hydraulic tensioner system (pressure 0.5-1.2MPa) and the innovative hexagonal locking module, a single operator can replace the screen within an astounding 10 minutes, slashing downtime by 70%.
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the comprehensive sand treatment process chain encompassing sand dropping, screening, cooling, and regeneration, fostering a cutting-edge intelligent sand treatment ecosystem:
High-temperature old sand pretreatment:
Directly interfacing with the vibrating sand dropping machine's outlet, our system expertly processes old sand embedded with iron beans (≤20mm) along with pouring and riser residues. The magnetic separation module, operating at a formidable 1500Gs, efficiently extracts iron impurities with a striking >99% success rate, tripling the screen's resistance to impact and wear.
With an airtight structure (leakage rate <3mg/m³) synergized with a pulse dust collector, our system maintains a dust concentration below 5mg/m³ in the working vicinity, while keeping noise levels at a mere ≤78dB(A).
Precise sand quality control:
Experience unparalleled precision with our advanced three-level screening system (Φ5mm/Φ1mm/Φ0.2mm) that meticulously grades regenerated sand, micro powder, and waste slag. This innovative technology ensures sand particle uniformity with a CU value of ≤1.2, significantly enhancing the casting surface smoothness to a remarkable Ra6.3μm.
Our state-of-the-art screening process achieves a remarkable efficiency of over 98%, with the impurity content of screened sand kept under an impressive 0.1%. This breakthrough reduces the need for new sand replenishment by an astounding 50%, leading to substantial cost savings and environmental benefits.
The pinnacle of operational excellence, our equipment boasts an outstanding Overall Equipment Efficiency (OEE) of 93%, with a robust Mean Time Between Failures (MTBF) exceeding 15,000 hours. This ensures uninterrupted productivity and maximizes your investment's return.
