Product Description
With an innovative approach, we implement a large-end feeding and small-end discharging (spindle tilting installation) system to dramatically enhance screening capacity. Our high-speed mechanism enables materials to descend from a strategically calculated height, ensuring effective crushing and screening.
Our long hole net, constructed from cold-drawn stainless steel braided mesh, guarantees exceptional durability, particularly under hot and humid conditions. The hexagonal structure outside the screen is expertly tensioned and secured, ensuring a robust surface that resists breakage, boasts excellent rebound properties, and is easily replaceable.
We employ powerful ventilation at the air inlet, meticulously cooling the sand and expertly managing the mud content of recycled sand, ensuring optimal quality and efficiency.
In the intricate process of foundry sand treatment and regeneration, the swift cooling and precise screening of high-temperature wet sand (temperature 80-150ºC, moisture content 3-8%) stand as the pivotal factors for enhancing the reuse rate of molding sand. Our advanced inclined spindle screening machine delivers a comprehensive sand treatment solution for foundries, featuring a blend of innovative dynamic design, high-temperature-resistant structural optimization, and an intelligent temperature control system. This article will thoroughly explore how our equipment achieves a groundbreaking enhancement in both screening efficiency and sand quality management across technical principles, process adaptability, energy efficiency optimization, and industry applications.
1. Technological Innovation and Core Design Breakthrough
Addressing the industry's critical challenges of clogging and high wear in hot and wet sand screening, our equipment has pioneered technological advancements through dynamic optimization and material innovation:
Tilted Spindle Dynamic Design:
Our spindle, meticulously set at an inclination of 15°-25°, integrates with a large-end feed port (Φ600-1200mm) and a high-performance vibration motor (speed 900-1500r/min). Sand particles follow a parabolic trajectory (initial velocity 2-5m/s), facilitating simultaneous impact crushing and screening. Our system achieves a processing capacity of 20-80t/h, a remarkable 40% improvement over conventional horizontal screening machines.
Double-Center Adjustment System: By dynamically balancing the vibration trajectory with an adjustable counterweight block (±5kg), we maintain amplitude fluctuation rates under 5% and elevate 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 long hole mesh features an aperture range of Φ0.2-5mm and a hexagonal honeycomb structure (opening rate 35-60%). This design enhances screen tensile strength by 50%, extends service life beyond 8000 hours, and stands resilient in environments up to 300ºC.
Quick-Release Tension Fixing System: Utilizing an efficient hydraulic tensioner (pressure 0.5-1.2MPa) coupled with a hexagonal locking module, a single operator can execute screen replacements within 10 minutes, reducing downtime by an impressive 70%.
2. Full-Process Integrated Solution for Foundry Sand Treatment
Our equipment seamlessly integrates into the sand dropping-screening-cooling-regeneration process chain, establishing an intelligent sand treatment ecosystem:
High-Temperature Old Sand Pretreatment:
Directly connecting to the vibrating sand dropping machine's outlet, our system efficiently processes old sand containing iron particles (≤20mm) and pouring and riser residues. The magnetic separation module (1500Gs) achieves iron impurity separation with over 99% efficiency, while enhancing screen impact and wear resistance by threefold.
Our enclosed structure (leakage rate <3mg/m³) is integrated with a pulse dust collector, ensuring dust concentration in the working environment remains below 5mg/m³, with noise levels not exceeding 78dB(A).
Precise Sand Quality Control:
Introducing our state-of-the-art three-level screening system, meticulously designed with precision grading capabilities (Φ5mm/Φ1mm/Φ0.2mm) to expertly classify regenerated sand, micro powder, and waste slag. This advanced system ensures sand particle uniformity with an impressive CU value of ≤1.2, contributing to an exceptional casting surface smoothness, achieving an unparalleled Ra6.3μm.
Boasting a remarkable screening efficiency of over 98%, our system significantly reduces impurities, maintaining screened sand impurity content below an impressive 0.1%. This high level of efficiency translates to a 50% reduction in the need for new sand replenishment, optimizing resource use and cost efficiency.
The pinnacle of reliability and performance, our equipment delivers an impressive Overall Equipment Efficiency (OEE) of 93%. With an outstanding Mean Time Between Failures (MTBF) surpassing 15,000 hours, our system ensures continuous, reliable operation, minimizing downtime and maximizing productivity.
