Product Description
Our cutting-edge sieve solutions embrace the innovative large-end feeding and small-end discharging method, enhanced by a tilted spindle installation. This technique maximizes screening potential, enabling materials to cascade dynamically from elevated positions, ensuring optimal crushing and screening at high velocities.
Meticulously engineered, our long hole net features cold-drawn stainless steel braiding, ensuring extraordinary durability and performance, especially under hot and humid conditions. The hexagonal arrangement outside the screen allows for optimal tension and fixation, preventing surface breakage. This design guarantees an excellent rebound effect, ensuring effortless replacements.
Robust ventilation at the air inlet plays a crucial role in cooling the sand efficiently, while adeptly regulating the mud content in the reclaimed sand, thus maintaining quality and consistency.
In our advanced foundry sand treatment and regeneration process, achieving rapid cooling and precise screening of high-temperature wet sand forms the cornerstone of enhancing mold sand reuse rates. Our inclined spindle screening machine delivers a comprehensive sand treatment solution for foundry workshops through pioneering dynamic designs, optimized high-temperature-resistant structures, and a sophisticated temperature control system. This detailed analysis delves into how our equipment excels in both screening efficiency and sand quality management, evaluated through technological principles, process adaptability, energy efficiency, and industry applications.
1. Technological innovation and core design breakthrough
Addressing industry challenges of clogging and significant wear in hot, wet sand screening, our equipment achieves remarkable technological advancements through dynamic optimization and material innovations:
Tilted spindle dynamic design:
Our spindle, expertly installed at a 15°-25° inclination, collaborates with a large-end feed port (Φ600-1200mm) and a high-performing vibration motor (speed 900-1500r/min). As sand particles traverse the screen along a parabolic path (initial velocity 2-5m/s), they undergo simultaneous impact, crushing, and screening. This results in a processing capacity of 20-80t/h, surpassing horizontal screening machines by 40%.
Double-center adjustment system: This system employs a counterweight block (adjustable ±5kg) to dynamically balance the vibration trajectory, maintaining amplitude fluctuation rates under 5% and elevating screening precision (AFS particle size standard deviation) to ±0.1mm.
Cold-drawn stainless steel woven screen:
Constructed using 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long hole mesh (aperture Φ0.2-5mm) with a hexagonal honeycomb structure (opening rate 35-60%) significantly boosts tensile strength by 50%. With a service life exceeding 8000 hours, it's tailored for high-impact, 300ºC sand environments.
Quick-release tension fixing system: By harnessing a hydraulic tensioner (pressure 0.5-1.2MPa) and hexagonal locking module, a solo operator can seamlessly replace screens in under 10 minutes, slashing downtime by an impressive 70%.
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the sand dropping-screening-cooling-regeneration process chain, forging an intelligent sand treatment ecosystem:
High-temperature old sand pretreatment:
Seamlessly linked to the vibrating sand dropping machine outlet, it processes old sand containing iron beans (≤20mm) and pouring and riser residues. The integrated magnetic separation module (1500Gs) boasts an iron impurity separation efficiency exceeding 99%, enhancing screen impact and wear resistance by a factor of three.
The closed structure, minimizing leakage to <3mg/m³, connects to a pulse dust collector, maintaining work area dust concentrations below 5mg/m³ and noise levels at ≤78dB(A).
Precise sand quality control:
Our innovative three-level screening system is engineered for precision, offering meticulous grading with diameters of Φ5mm, Φ1mm, and Φ0.2mm to expertly sort regenerated sand, micro powder, and waste slag. This advanced mechanism ensures that your sand particle uniformity boasts a CU value of ≤1.2, significantly enhancing the casting surface to achieve an impressive roughness level of Ra6.3μm.
Experience unparalleled efficiency with our screening technology, achieving an outstanding efficiency of over 98% and ensuring impurity content in screened sand is kept to an impressive low of less than 0.1%. This remarkable efficiency translates to a drastic 50% reduction in the need for new sand replenishment, optimizing your operations and reducing costs.
Our systems set the industry benchmark with an exceptional Overall Equipment Efficiency (OEE) reaching an impressive 93%. Coupled with a robust Mean Time Between Failures (MTBF) exceeding 15,000 hours, our solutions promise unparalleled reliability and longevity, ensuring seamless productivity and reduced downtime for your operations.
