Product Description
Featuring an innovative design, the Green Sand Casting Old Sand Screen enhances screening capabilities through its unique large-end feeding and small-end discharging system, implementing a spindle tilting installation. This advanced mechanism ensures that materials, propelled by high-speed dynamics, cascade from elevated positions, optimizing both crushing and screening processes.
Crafted with precision, the long hole net is composed of cold-drawn stainless steel braided mesh which boasts exceptional durability. This makes it particularly adept at handling hot and humid materials. The hexagonal configuration provides interlocking tension, minimizing surface breakage, enhancing rebound resilience, and facilitating effortless replacement.
The system employs robust ventilation at the air inlet, efficiently cooling the sand while meticulously managing the mud content within the reclaimed sand, thereby enhancing the quality of the output.
A pivotal element in the foundry sand treatment and regeneration sequence is the swift cooling and precise screening of high-temperature, moist sand (temperature range 80-150ºC, moisture content 3-8%). The inclined spindle screening machine stands out by delivering a comprehensive sand treatment solution, specially tailored for foundry workshops. This is achieved through an inventive dynamic design, thermal resistance structural upgrades, and an intelligent temperature regulation system. This article will delve into the equipment's dual advancements in screening efficiency and sand quality management, exploring aspects such as technical principles, process adaptability, energy optimization, and industry applications.
1. Technological Innovation and Core Design Breakthrough
Addressing critical industry challenges of clogging and high wear in hot, wet sand screening, the equipment has made significant technological strides with dynamic optimizations and groundbreaking material enhancements:
Tilted Spindle Dynamic Design:
The spindle's strategic inclination, set between 15°-25°, works in harmony with the large-end feed port (Φ600-1200mm) and a high-performance vibration motor (operating at speeds between 900-1500r/min). This synergy propels sand particles along a parabolic path (with an initial velocity of 2-5m/s), achieving concurrent impact, crushing, and screening. This method elevates processing capacity to 20-80t/h, surpassing traditional horizontal screening machines by 40% in efficiency.
Double-Center Adjustment System: Featuring a counterweight block (adjustable by ±5kg) for dynamically balanced vibration trajectories, the amplitude fluctuation rate is maintained under <5%, enhancing screening accuracy (AFS particle size standard deviation) to an impressive ±0.1mm.
Cold-Drawn Stainless Steel Woven Screen:
Constructed with 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), the screen's long hole mesh (aperture Φ0.2-5mm) and hexagonal honeycomb structure (with an opening rate of 35-60%) significantly bolster its tensile strength by 50%, ensuring a service life exceeding 8000 hours and suitability for sand impact at temperatures up to 300ºC.
Quick-Release Tension Fixing System: Utilizing a hydraulic tensioner (pressure range 0.5-1.2MPa) combined with a hexagonal locking module, this system empowers a single operator to execute a screen replacement in under 10 minutes, slashing downtime by an impressive 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
The equipment seamlessly integrates into the comprehensive process chain of sand dropping, screening, cooling, and regeneration, establishing an intelligent sand treatment ecosystem:
High-Temperature Old Sand Pretreatment:
Engineered for direct connection to the outlet of the vibrating sand dropping machine, this system adeptly processes old sand laden with iron beans (≤20mm) and residues from pouring and risers. The magnetic separation module (1500Gs) exhibits outstanding efficiency, removing iron impurities with a success rate exceeding 99%, while the screen's impact and wear resistance is enhanced threefold.
The structure flaunts a closed design (leakage rate <3mg/m³) linked to a pulse dust collector, effectively maintaining dust concentrations in the working area to <5mg/m³, all while keeping noise levels at or below 78dB(A).
Precise Sand Quality Control:
Experience the pinnacle of precision with our state-of-the-art three-level screening system, featuring meticulous grading capabilities across Φ5mm, Φ1mm, and Φ0.2mm thresholds. This advanced system expertly segregates regenerated sand, micro powder, and waste slag, ensuring sand particle uniformity with a CU value that impressively measures ≤1.2. Such precision in grading allows your casting projects to achieve an exceptional surface roughness, reaching a remarkable Ra6.3μm.
Elevate your production efficiency with our cutting-edge screening technology, boasting an impressive efficiency rate of over 98%. This ensures that the impurity content of the screened sand is kept remarkably low at less than 0.1%. Such superior performance enables a reduction in new sand replenishment by a substantial 50%, driving down costs and enhancing sustainability.
Maximize your operational capability with our top-tier equipment, achieving an Overall Equipment Efficiency (OEE) of an impressive 93%. Experience unparalleled reliability with a Mean Time Between Failures (MTBF) exceeding 15,000 hours, ensuring continuous, smooth operation and reduced downtime, which together optimize productivity and maintain quality standards.
