Product Description
Elevate your sand processing efficiency with our cutting-edge Tailored Blade Aerator and Sand Cutter! Specifically engineered to be installed above the sand conveying belt, this innovative machine effortlessly breaks up green sand into a loose state after mixing, ensuring optimal performance and superior results every time.
In the world of green sand casting, where precision and quality are paramount, our Tailored Blade Aerator and Sand Cutter shines as a game-changer. Designed for mechanized sand recycling production lines, this powerful machine excels at loosening mixed wet sand and crushing old sand after separation. With its seamless integration into the dust removal pipeline, it tackles the challenge of sand agglomeration that affects molding sand's air permeability and casting surface quality. As a core component of the sand processing ecosystem, our sand loosening machine revolutionizes the modern foundry workshop with its robust loosening capabilities, efficient crushing, and intelligent dust removal. This article delves deep into how this machine empowers foundry companies to achieve efficient sand regeneration and clean production, focusing on technological innovation, process adaptability, environmental protection, and intelligent control.
1. Process pain points and technological innovation
Addressing the critical challenges of wet sand compaction (with a water content of 3-5%) post-mixing and the crushing demands of old sand (laden with core bone and iron bean impurities), our loose sand machine pioneers technological advancements through its dual-mode crushing structure and modular design:
Wet sand loosening mode:
Experience unparalleled efficiency with our Rotary Knife Crushing System, featuring a 304 stainless steel staggered blade group (hardness HRC55-60) that slices through sand blocks at an impressive speed of 1200r/min. With a remarkable processing capacity of 60t/h, the loosened molding sand boasts a bulk density of ≤1.4g/cm³, enhancing air permeability by 40% for superior casting quality.
Dynamic Screening Module: Equipped with a built-in Φ8mm aperture grid, this module synchronously separates any unbroken large particles with a return rate of less than 2%, ensuring the molding sand enters the conveyor belt with remarkable uniformity and a particle size standard deviation of less than 0.15mm.
Old sand crushing mode:
Harness the power of the Hammer Impact Mechanism, armed with a high manganese steel hammer head (impact toughness ≥120J/cm²), to effortlessly crush old sand groups containing iron beans (diameter ≤20mm). Achieving a crushing efficiency of 45t/h, this mechanism separates iron impurities with a staggering rate of over 98%.
Magnetic Pre-Separation: The installation of a permanent magnetic roller (magnetic induction strength ≥1500Gs) atop the system pre-adsorbs ferromagnetic impurities, significantly reducing hammer head wear by an impressive 70%.
Intelligent switching technology:
Our PLC-controlled system enables seamless one-button switching between wet sand and old sand processing modes, achieving conversion times of less than 3 minutes. Ideal for both intermittent and continuous production line layouts, it offers unparalleled flexibility and efficiency.
2. Integrated solution for foundry sand processing line
Achieve unparalleled synergy in your sand processing ecosystem with the collaborative operations of our loose sand machine, conveyor belt, and dust removal system, all working together to optimize efficiency and performance.
Space optimization design:
Our inverted installation structure allows direct erection above the B=800-1400mm belt conveyor, with a net height of ≤1.2m, saving an impressive 30% of vertical workshop space and maximizing your production area.
Seamlessly connect your sand mixer and old sand screening machine with our standard inlet and outlet flanges (ISO 5211), accommodating a connection error of just ±2mm for a flawless operational flow.
Easy maintenance:
Designed for convenience, our quick-detachable cutter head and hammer bracket allow for tool replacements in under 20 minutes, minimizing downtime and enhancing productivity.
With gas spring-assisted observation windows and inspection doors, a single operator can effortlessly perform daily maintenance tasks, ensuring smooth operations and long-lasting equipment performance.
3. Core advantages and economic benefits
The loose sand machine represents a qualitative leap in foundry sand processing, harnessing material innovation and intelligent control to deliver unmatched performance and efficiency. Discover the transformative impact of advanced technology on your foundry operations today!
Introducing a design that stands the test of time with wear-resistant and enduring features:
Crafted with precision, the blade surface boasts a state-of-the-art laser-clad tungsten carbide coating, with a thickness ranging from 0.3-0.5mm, dramatically extending its lifespan by an impressive fourfold compared to traditional blades;
Engineered for affordability, the box lining is easily replaced with the premium-grade ARQ wear-resistant steel plate, boasting a hardness of HB450, slashing annual maintenance expenses by a remarkable 65%.
