Product Description
Our advanced screening solution utilizes an innovative spindle tilting installation to significantly enhance screening capabilities. By employing large end feeding and small end discharging, the system ensures efficient material sorting. The elevated speed propels materials from a high vantage point, facilitating both crushing and screening in one seamless motion.
The screen is crafted from cold-drawn stainless steel braided nets, delivering exceptional longevity and perfectly suited for high-temperature, humid environments. The hexagonal configuration outside the screen ensures a secure fit and optimal tensioning, guarding against surface damage. This design provides a superior rebound effect and allows for effortless screen replacement.
Our system features robust ventilation at the air inlet to effectively cool sand and meticulously manage the mud content within the reclaimed sand, ensuring optimal purity and performance.
The pivotal process of foundry sand treatment and regeneration is marked by the swift cooling and precise screening of high-temperature wet sand, which ranges from 80-150ºC with a moisture content of 3-8%. Our inclined spindle screening apparatus offers a comprehensive sand management solution to foundry workshops, boasting an innovative design, a robust heat-resistant structure, and an intelligent temperature regulation system. This document provides an in-depth exploration of how our equipment achieves remarkable advancements in both screening efficiency and sand quality governance through cutting-edge technical principles, process adaptability, energy optimization, and versatile industrial applications.
1. Unveiling Technological Innovation and Core Design Advancements
Addressing the prevalent industry challenges of clogging and significant wear during hot and wet sand screening, our equipment pioneers technological advancements through dynamic optimizations and material breakthroughs:
Characterized by a Tilted Spindle Dynamic Design:
The spindle, installed at a strategic inclination of 15°-25°, synergizes with the large end feed port (Φ600-1200mm) and high-efficiency vibration motor (operating at 900-1500r/min). This collaboration propels sand particles along a parabolic trajectory with initial velocities of 2-5m/s, achieving concurrent impact crushing and screening. With a processing capacity of 20-80t/h, this system delivers a staggering 40% increase in efficiency compared to traditional horizontal screening machines.
Innovative Double-Center Adjustment System: The vibration trajectory achieves dynamic equilibrium via an adjustable counterweight block (±5kg), maintaining amplitude fluctuations under 5%, while enhancing screening precision to a remarkable ±0.1mm deviation according to AFS particle size standards.
Revolutionary Cold-Drawn Stainless Steel Woven Screen:
Engineered with robust 316L stainless steel cold-drawn wire (tensile strength ≥ 520MPa) to form a long hole mesh with apertures ranging from Φ0.2-5mm, the screen's hexagonal honeycomb architecture (boasting an opening rate of 35-60%) amplifies tensile strength by 50% and ensures a service life exceeding 8000 hours, thriving even in 300ºC high-temperature sand impact conditions.
Rapid Quick-Release Tension Fixing System: Utilizing a hydraulic tensioner (pressure 0.5-1.2MPa) paired with a hexagonal locking module, a solo operator can effortlessly execute screen replacements within merely 10 minutes, slashing downtime by an impressive 70%.
2. Comprehensive Integrated Foundry Sand Treatment Solution
Our advanced equipment meticulously integrates with the sand treatment process chain—comprising sand dropping, screening, cooling, and regeneration—crafting an intelligent sand management ecosystem:
Efficient High-Temperature Old Sand Pretreatment:
Seamlessly connected to the outlet of the vibrating sand dropping machine, our system adeptly processes old sand laden with iron fragments (up to 20mm) and residual pour and riser materials. Equipped with a magnetic separation module offering 1500Gs, it achieves an iron impurity separation efficiency exceeding 99%, tripling the screen's impact and wear resistance.
The enclosed structure (boasting a leakage rate of less than 3mg/m³) integrates with a pulse dust collector, maintaining a work area dust concentration below 5mg/m³ and ensuring operational noise levels are ≤78dB(A).
Advanced Precise Sand Quality Control:
Our state-of-the-art three-level screening system, featuring precise gradations of Φ5mm, Φ1mm, and Φ0.2mm, effectively classifies regenerated sand, micro powder, and waste slag. This meticulous process ensures a sand particle uniformity with a CU value of ≤1.2, thereby achieving an impeccable casting surface roughness of Ra6.3μm.
Achieving a remarkable screening efficiency of over 98%, our system ensures that the impurity content of the screened sand remains under a minuscule 0.1%. This high level of purity significantly reduces the need for new sand replenishment by an impressive 50%, optimizing resource use and cost-efficiency.
With an Overall Equipment Efficiency (OEE) reaching an outstanding 93%, and a Mean Time Between Failures (MTBF) surpassing 15,000 hours, our system guarantees superior performance and reliability, minimizing downtime and maximizing productivity.
