Product Description
Our cutting-edge Customized Green Sand Casting Old Sand Screen, featuring a revolutionary large-end feeding and small-end discharging system (spindle tilting installation), significantly enhances screening capabilities. Thanks to its high-speed operation, materials cascade from elevated heights to facilitate optimal crushing and screening, ensuring superior performance and efficiency.
Engineered for durability, our product utilizes a cold-drawn stainless steel braided net with extended lifespan, perfect for processing hot and humid materials. The hexagon exterior is tightly interlocked, preventing screen breakage, ensuring a robust rebound effect, and simplifying replacement. Experience unmatched functionality with a screen designed for longevity and resilience.
Our advanced system incorporates powerful ventilation at the air inlet, effectively cooling the sand and regulating the mud content within the old sand. This precise control mechanism enhances the overall quality and usability of the sand, ensuring it meets the highest industry standards.
In the quest for superior sand quality, the foundry sand treatment and regeneration process hinges on rapidly cooling and precisely screening high-temperature wet sand (80-150ºC, moisture 3-8%). Our inclined spindle screening machine delivers a comprehensive sand treatment solution through its innovative dynamic design, high-temperature-resistant structure, and intelligent temperature control system. This article delves into the double breakthroughs in screening efficiency and sand quality management, exploring technical principles, process adaptability, energy efficiency, and industry applications that elevate performance and reliability.
1. Technological innovation and core design breakthrough
Addressing critical industry challenges of clogging and wear in hot, wet sand screening, our equipment triumphs with dynamic optimization and material innovation, setting new benchmarks for performance and durability.
Tilted spindle dynamic design:
The spindle's 15°-25° inclination, coupled with large end feed ports (Φ600-1200mm) and high-speed vibration motors (900-1500r/min), propels sand particles in a parabolic trajectory (initial velocity 2-5m/s). This dynamic system enables concurrent impact crushing and screening, achieving processing capabilities of 20-80t/h, a remarkable 40% increase over traditional horizontal screens.
Double-center adjustment system: Featuring precision-tuned counterweight blocks (adjustable ±5kg), our system dynamically balances vibration trajectories, maintaining an amplitude fluctuation rate of <5% and elevating screening accuracy to an impressive ±0.1mm AFS particle size standard deviation.
Cold-drawn stainless steel woven screen:
Crafted with 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), our long-hole mesh (aperture Φ0.2-5mm) exhibits a hexagonal honeycomb structure (opening rate 35-60%), enhancing tensile strength by 50% and offering a service life exceeding 8000 hours, expertly suited for 300ºC high-temperature sand impact environments.
Quick-release tension fixing system: With our hydraulic tensioner (pressure 0.5-1.2MPa) and hexagonal locking module, a single operator can 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 treatment process chain, from sand dropping to screening, cooling, and regeneration, creating an intelligent ecosystem that optimizes efficiency and quality.
High-temperature old sand pretreatment:
Directly interfacing with the vibrating sand dropping machine outlet, our system processes old sand containing iron beans (≤20mm) and riser residues. The magnetic separation module (1500Gs) efficiently isolates iron impurities, achieving a >99% separation efficiency and tripling the impact and wear resistance of the screen.
Enclosed within a leak-proof structure (leakage rate <3mg/m³) connected to a pulse dust collector, we maintain a dust-free working environment with concentrations <5mg/m³ and noise levels ≤78dB(A), ensuring a safe and productive workspace.
Precise sand quality control:
Our exceptional three-level screening system, featuring precision grades of Φ5mm, Φ1mm, and Φ0.2mm, meticulously classifies regenerated sand, micro powder, and waste slag. This advanced grading ensures a sand particle uniformity (CU value) of ≤1.2, significantly contributing to a superior casting surface finish with roughness reaching an impressive Ra6.3μm.
Achieving a remarkable screening efficiency of over 98%, our system ensures that the impurity content in the screened sand remains under 0.1%. Such efficiency dramatically decreases the necessity for new sand replenishment by a substantial 50%, optimizing resource utilization and cost efficiency.
With an outstanding Overall Equipment Efficiency (OEE) level of 93%, our system promises exceptional reliability. The Mean Time Between Failures (MTBF) exceeds 15,000 hours, ensuring prolonged and uninterrupted operation, setting a new standard in equipment performance.
