Product Description
To amplify the screening abilities, our design embraces a large end feeding and small end discharging with a precisely tilted spindle installation. This intelligent configuration, coupled with high-speed operation, ensures materials descend from an elevated position, maximizing both crushing and screening efficiency.
Our innovative long hole net, crafted from cold-drawn stainless steel braided mesh, is engineered for longevity and unmatched performance, especially in hot, humid conditions. The hexagonal external structure offers robust tensioning and secure fixation, enhancing the screen's durability. This prevents surface breakage, delivers superior rebound effects, and simplifies replacement.
We employ a robust ventilation system at the air inlet to effectively cool sand and meticulously control the mud content in recycled sand, promoting optimal performance.
In the critical process of foundry sand treatment and regeneration, the rapid cooling and precise screening of high-temperature wet sand—ranging from 80-150ºC with moisture content of 3-8%—is vital for enhancing the reusability of molding sand. Our cutting-edge inclined spindle screening machine offers a comprehensive sand treatment solution for foundry workshops. By leveraging innovative dynamic designs, a high-temperature resistant structure, and an advanced intelligent temperature control system, this equipment achieves exceptional breakthroughs in both screening efficiency and sand quality management. This article delves into the technical principles, process adaptability, energy-efficient optimization, and industry applications that empower this equipment to elevate industry standards.
1. Technological Innovation and Core Design Breakthroughs
Confronting the industry's major challenges of clogging and high wear in hot, wet sand screening, our equipment introduces groundbreaking solutions through dynamic optimization and material innovations:
Tilted Spindle Dynamic Design:
Our spindle is expertly installed at a 15°-25° incline, alongside a large end feed port (Φ600-1200mm) and a high-performance vibration motor (900-1500r/min). This synergy propels sand particles against the screen in a parabolic motion (initial velocity of 2-5m/s), enabling simultaneous impact crushing and screening. This design elevates processing capacity to 20-80t/h, a remarkable 40% boost over traditional horizontal screening machines.
Double-Center Adjustment System: This system dynamically balances the vibration trajectory through a counterweight block (adjustable ±5kg). It ensures amplitude fluctuation remains below 5%, while increasing screening precision (AFS particle size standard deviation) to an impressive ±0.1mm.
Cold-Drawn Stainless Steel Woven Screen:
Crafted with 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our screens weave long hole mesh with an aperture range of Φ0.2-5mm, forming a hexagonal honeycomb structure (opening rate 35-60%). This design enhances tensile strength by 50%, offers a service life exceeding 8000 hours, and is ideally suited for intense conditions up to 300ºC.
Quick-Release Tension Fixing System: Utilizing a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, a single operator can efficiently replace screens in under 10 minutes, cutting downtime by 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
This equipment seamlessly integrates into the sand dropping-screening-cooling-regeneration process chain, constructing an intelligent sand treatment ecosystem:
High-Temperature Old Sand Pretreatment:
Strategically connected to the vibrating sand dropping machine's outlet, it processes old sand with iron beans (≤20mm) and pouring riser residues. Our magnetic separation module (1500Gs) achieves iron impurity separation efficiency exceeding 99%, while the screen's impact and wear resistance is tripled.
Featuring a closed structure (leakage rate <3mg/m³), it's interconnected with a pulse dust collector, maintaining dust concentration in work areas below 5mg/m³, and noise levels at ≤78dB(A).
Precise Sand Quality Control:
Behold the unparalleled precision of our three-level screening system, boasting distinctive apertures (Φ5mm/Φ1mm/Φ0.2mm), which meticulously classifies regenerated sand, micro powder, and waste slag. Revel in the sand particle uniformity, where the CU value is an impressive ≤1.2. This meticulous grading ensures that your casting surfaces attain a remarkably smooth roughness of Ra6.3μm, elevating the quality and precision of your production.
Experience screening mastery with an outstanding efficiency exceeding 98%. The purity of your screened sand is unmatched, maintaining impurity content at a mere <0.1%. Witness a dramatic 50% reduction in the need to replenish new sand, ensuring both cost efficiency and resource conservation, a true testament to our advanced technology.
Our equipment stands as a paragon of reliability, with an Overall Equipment Efficiency (OEE) reaching an impressive 93%. Benefit from the extraordinary durability with a Mean Time Between Failures (MTBF) exceeding 15,000 hours, ensuring seamless operation and minimal downtime for your production lines.
