Product Description
By employing a sophisticated design of large end feeding and small end discharging through spindle tilting installation, we've significantly enhanced the screening capacity of our Customizable Sieve. With high-speed operation, materials cascade from elevated points, facilitating effective crushing and screening like never before.
Our long hole net is crafted from cold-drawn stainless steel braided mesh, offering an extended service life. This construction is ideally suited for hot and humid materials. The hexagonal structure outside the screen ensures robust tensioning or fixing, minimizing surface damage, offering excellent rebound, and making replacement a breeze.
Our innovative strong ventilation system effectively cools the sand at the air inlet, efficiently controlling the mud content in recycled sand for optimal performance.
In the realm of foundry sand treatment and regeneration, rapid cooling and precise screening of high-temperature, wet sand (between 80-150ºC with moisture content of 3-8%) are critical to enhancing the reuse rate of molding sand. Our inclined spindle screening machine provides a comprehensive sand treatment solution for foundry workshops. It does so with an innovative dynamic design, high-temperature resistant structure optimization, and an intelligent temperature control system. This in-depth analysis explores how our equipment achieves a breakthrough in both screening efficiency and superior sand quality management, addressing technical principles, process adaptability, energy efficiency, and industry applications.
1. Technological Innovation and Core Design Breakthrough
To address industry challenges like easy clogging and high wear during hot, wet sand screening, our equipment has achieved remarkable technological strides through dynamic optimization and material innovation:
Tilted Spindle Dynamic Design:
Our spindle is ingeniously installed at an inclination of 15°-25°, with the large end feed port (Φ600-1200mm) working in tandem with a vibration motor (speed 900-1500r/min). Sand particles follow a parabolic trajectory (initial velocity 2-5m/s), achieving effective impact crushing and screening simultaneously. The processing capacity reaches up to 20-80t/h, marking a 40% increase over traditional horizontal screening machines.
Double-Center Adjustment System: Our dynamic balance of the vibration trajectory is achieved with a counterweight block (adjustable ±5kg), ensuring amplitude fluctuation rates remain <5%, and enhancing screening precision with an AFS particle size standard deviation of ±0.1mm.
Cold-Drawn Stainless Steel Woven Screen:
We utilize 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa) to weave our long hole mesh (aperture Φ0.2-5mm) with a hexagonal honeycomb structure (opening rate 35-60%). This increases the tensile strength of the screen by 50%, extending its service life beyond 8000 hours, and making it apt for high-temperature sand impact environments of up to 300ºC.
Quick-Release Tension Fixing System: With a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single technician can replace the screen in less than 10 minutes, reducing downtime by 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
Our equipment seamlessly integrates into the sand dropping, screening, cooling, and regeneration process chain, creating an intelligent sand treatment ecosystem.
High-Temperature Old Sand Pretreatment:
Directly linked to the outlet of the vibrating sand dropping machine, our system processes old sand containing iron beans (≤20mm) and pouring and riser residues. The magnetic separation module (1500Gs) efficiently removes iron impurities with a >99% success rate, tripling the impact and wear resistance of the screen.
Our closed structure (leakage rate <3mg/m³) connects to a pulse dust collector, maintaining dust concentration in the work area at <5mg/m³ and ensuring noise levels remain ≤78dB(A).
Precise Sand Quality Control:
Experience the unparalleled precision of our triple-tiered screening system, featuring mesh sizes of Φ5mm, Φ1mm, and Φ0.2mm. This advanced grading process meticulously sorts regenerated sand, micro powder, and waste slag with remarkable accuracy. The result is a sand particle uniformity boasting a CU value of ≤1.2, which significantly enhances the casting surface's smoothness, achieving an impressive roughness of Ra6.3μm.
Our state-of-the-art screening technology guarantees an extraordinary efficiency of over 98%, while ensuring that the impurity content of the processed sand remains under a meticulous 0.1%. This not only elevates the quality of your sand but also dramatically reduces the need for new sand by a remarkable 50%, optimizing your resources and maximizing productivity.
Our equipment stands as a testament to engineering excellence, with an Overall Equipment Efficiency (OEE) soaring to 93%. Designed for durability and reliability, it offers an impressive Mean Time Between Failures (MTBF) exceeding 15,000 hours, ensuring your operations run seamlessly with minimal interruptions and maximum output.
