Product Description
Discover our cutting-edge Green Sand Casting Old Sand Screen, which showcases a dynamic and innovative design. Featuring a wide-end feeding system and a narrow-end discharging system due to its ingeniously tilted spindle installation, this advanced equipment maximizes screening efficiency. As materials cascade from greater heights, the system ensures superior crushing and screening prowess at remarkable speeds, redefining productivity and performance.
Impeccably crafted with precision, the long hole net is composed of cold-drawn stainless steel braided mesh, ensuring outstanding durability. Perfectly suited for managing hot and humid materials, the hexagonal tensioned design prevents breakage and offers excellent rebound. This design allows for effortless screen replacement, significantly reducing downtime and enhancing operational efficiency.
Equipped with robust ventilation at the air inlet, our system proficiently cools the sand while expertly managing mud content. This feature safeguards the quality and integrity of the old sand, ensuring optimal preservation and performance.
In the intricate cycle of foundry sand treatment and regeneration, rapid cooling and precise screening of high-temperature wet sand (80-150ºC, 3-8% moisture) are crucial for enhancing the reuse rate of molding sand. Our innovative inclined spindle screening machine is a comprehensive solution for foundry workshops. With pioneering dynamic design, it features optimized high-temperature resistant structures and an intelligent temperature control system. This deep exploration reveals how this state-of-the-art equipment achieves dual advancements in screening efficiency and sand quality management across technical principles, process adaptability, energy efficiency, and industry application.
1. Technological innovation and core design breakthrough
Tackling industry challenges such as clogging and high wear during hot, wet sand screening, our equipment exemplifies technological advancements through optimized dynamics and innovative material use:
Tilted spindle dynamic design:
Strategically inclined at 15°-25°, our spindle harmonizes with a large-end feed port (Φ600-1200mm) and a high-speed vibration motor (900-1500r/min). This design propels sand particles along a parabolic path (initial velocity 2-5m/s) over the screen, facilitating effective impact crushing and screening. The system achieves an impressive processing capacity of 20-80t/h, surpassing traditional horizontal screeners by 40% in efficiency.
Double-center adjustment system: This system maintains a balanced vibration trajectory via an adjustable counterweight block (±5kg), ensuring amplitude fluctuation rates below 5%. This results in unparalleled screening precision, achieving an AFS particle size standard deviation of ±0.1mm and setting new industry benchmarks.
Cold-drawn stainless steel woven screen:
Constructed from 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa), this long hole mesh (aperture Φ0.2-5mm) features a hexagonal honeycomb structure (35-60% opening rate). This design bolsters tensile strength by 50% and offers a service life exceeding 8000 hours. It is engineered to endure high-temperature sand impact environments up to 300ºC.
Quick-release tension fixing system: Utilizing a hydraulic tensioner (pressure 0.5-1.2MPa) and a hexagonal locking module, screen replacement is achieved by a single operator in under 10 minutes, cutting downtime by up to 70%.
2. Full-process integrated solution for foundry sand treatment
Our system seamlessly integrates into the full sand treatment cycle, encompassing dropping, screening, cooling, and regeneration. This creates an intelligent and efficient sand treatment ecosystem, optimizing every step of the process.
High-temperature old sand pretreatment:
Directly linked to the outlet of the vibrating sand dropping machine, the system adeptly handles old sand with iron beans (≤20mm) and pouring residues. The integrated magnetic separation module (1500Gs) achieves an iron impurity removal efficiency of over 99%, significantly enhancing the screen's impact and wear resistance.
With a closed structure (leakage rate <3mg/m³), the system connects to a pulse dust collector, maintaining dust concentrations in the workspace below 5mg/m³, and ensures noise levels remain at a comfortable ≤78dB(A).
Precise sand quality control:
Experience the unparalleled precision of our cutting-edge three-level screening system. Crafted with meticulous attention to detail, it features multiple granularity levels at Φ5mm, Φ1mm, and Φ0.2mm, ensuring the perfect grading of regenerated sand, micro powder, and waste slag. This innovation guarantees an impressive uniformity in sand particles, with a CU value consistently ≤1.2. Such precision elevates the casting surface finish to an exceptional quality, achieving a remarkable Ra6.3μm.
Unlock extraordinary efficiency with our high-performance screening system, which boasts an incredible >98% efficiency rate. Our advanced technology maintains screened sand impurity content at an impressive <0.1%, significantly conserving resources. This optimized process reduces the necessity for new sand replenishment by a remarkable 50%, enhancing both sustainability and cost-effectiveness.
Our state-of-the-art equipment is expertly engineered to deliver unparalleled performance. It boasts an exceptional Overall Equipment Efficiency (OEE) of 93%, indicative of its superior productivity and reliability. With a Mean Time Between Failures (MTBF) exceeding an impressive 15,000 hours, this equipment assures steadfast reliability and unrivaled productivity, ensuring your operations run smoothly and effectively.
