Product Description
Experience unparalleled screening performance with our innovative design. Our product embraces a unique large-end feeding and small-end discharging setup. The strategically tilted spindle installation significantly amplifies screening efficiency. Thanks to a high-speed mechanism, materials descend artfully from a high vantage point, ensuring both effective crushing and meticulous screening.
Crafted for durability, our long-hole net design incorporates cold-drawn stainless steel braided with precision. Its extended service life makes it ideal for challenging hot and humid environments. The hexagonal external configuration ensures a taut, resilient surface that resists breakage, offers superior rebound, and facilitates effortless replacement.
Enhance sand cooling and maintain optimal sand quality with our robust ventilation system. Strategically positioned at the air inlet, it effectively cools sand while meticulously controlling the mud content of reclaimed sand.
In the realm of foundry sand treatment and regeneration, the swift cooling and accurate screening of high-temperature wet sand (80-150ºC with 3-8% moisture) are pivotal. Our inclined spindle screening machine revolutionizes the foundry workspace by offering a comprehensive sand treatment solution. Through cutting-edge dynamic design, a high-temperature resistant framework, and an intelligent temperature control system, this article delves into how our equipment achieves dual advancements in screening efficiency and sand quality management. Covering the technical principles, process adaptability, energy efficiency, and industry applications, we unveil the profound capabilities of our system.
1. Technological innovation and core design breakthrough
Addressing critical industry challenges of clogging and wear in hot, wet sand screening, our equipment pioneers advancements through dynamic enhancement and material innovation:
Tilted spindle dynamic design:
Our spindle configuration, inclined at a strategic 15°-25°, combines a large-end feed port (Φ600-1200mm) with a high-performance vibration motor (900-1500r/min). Sand particles follow a calculated parabolic path (velocity 2-5m/s), achieving concurrent impact, crushing, and screening. This results in an impressive processing capacity of 20-80t/h—40% more efficient than conventional horizontal screening solutions.
Double-center adjustment system: This innovative system ensures the dynamic balance of the vibration trajectory using a counterweight block (adjustable ±5kg). With an amplitude fluctuation rate of <5%, the screening precision (AFS particle size standard deviation) is enhanced to ±0.1mm.
Cold-drawn stainless steel woven screen:
Our screens, crafted from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), feature a long-hole mesh (aperture Φ0.2-5mm) with a hexagonal honeycomb structure (35-60% open rate). This design bolsters tensile strength by 50%, provides a service life exceeding 8000 hours, and thrives in high-temperature sand impact environments up to 300ºC.
Quick-release tension fixing system: Utilizing a hydraulic tensioner (pressure 0.5-1.2MPa) alongside a hexagonal locking module, our system allows a single operator to replace the screen in just 10 minutes, significantly reducing downtime by 70%.
2. Full-process integrated solution for foundry sand treatment
Our equipment seamlessly integrates into the crucial sand process chain—spanning sand dropping, screening, cooling, and regeneration—to create a sophisticated, intelligent sand treatment ecosystem.
High-temperature old sand pretreatment:
Seamlessly connected to the vibrating sand dropping machine's outlet, our system handles iron bean-laden old sand (≤20mm) and pouring residues. The advanced magnetic separation module (1500Gs) efficiently extracts iron impurities at a rate of >99%, enhancing the screen's impact and wear resistance by threefold.
A closed structure design (leakage rate <3mg/m³) works in tandem with the pulse dust collector, maintaining a dust concentration of <5mg/m³ in the working area and ensuring noise levels remain at ≤78dB(A).
Precise sand quality control:
Our pioneering three-level screening system, featuring precision grading at Φ5mm, Φ1mm, and Φ0.2mm, expertly sorts regenerated sand, micro powder, and waste slag. This meticulous process ensures exceptional sand particle uniformity with a CU value of ≤1.2, significantly enhancing casting surface smoothness to an impressive Ra6.3μm.
Experience unrivaled screening efficiency exceeding 98%, with impurity content in the screened sand impressively reduced to below 0.1%. This advanced performance effectively cuts down the need for new sand replenishment by an astounding 50%, optimizing resources and reducing costs.
Achieve peak performance with our equipment's Overall Equipment Efficiency (OEE) soaring to a remarkable 93%, complemented by a robust Mean Time Between Failures (MTBF) that exceeds an impressive 15,000 hours, ensuring steadfast reliability and operational excellence.
