Product Description
Strategically installed above the sand conveying belt, our innovative device masterfully transforms the green sand into a beautifully loose state following mixing, ensuring optimal performance and efficiency.
Specifically designed for the mechanized sand recycling production line in green sand casting, this versatile machine excels at loosening mixed wet sand and efficiently crushing old sand post-separation. It seamlessly integrates with dust removal systems, ensuring a pristine foundry environment. In the mechanized foundry sand recycling production line, the effectiveness of wet sand loosening post-mixing and old sand crushing critically influences the molding sand's permeability and the casting's surface quality. As the heart of the sand processing ecosystem, our sand loosening machine is revolutionizing modern foundry workshops with its powerful loosening, efficient crushing, and smart dust-removal functionalities. This comprehensive exploration unveils how our machine empowers foundries to achieve superior regeneration and eco-friendly sand resource management, driven by cutting-edge technology, adaptable processes, outstanding environmental efficiencies, and intelligent control.
1. Process Pain Points and Technological Innovation
Addressing the prevalent compaction issues of wet sand (3-5% moisture) after mixing and the demanding crushing needs of old sand (with core bone, iron impurities), our loose sand machine pioneers technological advancements with its dual-mode crushing structure and modular design:
Wet Sand Loosening Mode:
Our state-of-the-art rotary knife crushing system, featuring a 304 stainless steel staggered blade group (HRC55-60 hardness), operates at an impressive 1200r/min, handling 60 tons per hour. This system achieves a bulk density of ≤1.4g/cm³ for the loosened molding sand, boosting air permeability by an impressive 40%.
The dynamic screening module incorporates a built-in Φ8mm aperture grid, ensuring synchronous separation of unbroken large particles with a return rate of less than 2%. This guarantees the uniform distribution of molding sand on the conveyor belt, meeting a particle size standard deviation of less than 0.15mm.
Old Sand Crushing Mode:
Our hammer impact mechanism, equipped with a robust high manganese steel hammer head (impact toughness ≥120J/cm²), efficiently crushes old sand clusters containing iron beans (up to 20mm in diameter). It achieves a remarkable crushing efficiency of 45 tons per hour and an iron impurity separation rate exceeding 98%.
With magnetic pre-separation, a permanent magnetic roller (magnetic induction strength ≥1500Gs) effectively adsorbs ferromagnetic impurities in advance, reducing the wear rate of the hammer head by an impressive 70%.
Intelligent Switching Technology:
Effortlessly switch between wet sand and old sand processing modes with a single touch via PLC control. Conversion takes less than 3 minutes, perfectly suited for both intermittent and continuous production line layouts.
2. Integrated Solution for Foundry Sand Processing Line
Through the seamless collaboration of the loose sand machine, conveyor belt, and dust removal system, we create an exceptionally efficient sand processing ecosystem:
Space Optimization Design:
Featuring an inverted installation structure, our device is elegantly positioned above the B=800-1400mm belt conveyor, with a net height of ≤1.2m, offering a remarkable 30% vertical space saving in the workshop.
The standardized inlet and outlet flange design (ISO 5211) ensures seamless connectivity with the sand mixer and the old sand screening machine, with an acceptable connection error of just ±2mm.
Easy Maintenance:
Our quick-detachable cutter head and hammer bracket design allows for tool replacement in under 20 minutes, maximizing operational efficiency;
The gas spring-assisted opening of the observation window and inspection door enables individual personnel to accomplish daily maintenance effortlessly.
3. Core Advantages and Economic Benefits
Through the mastery of material innovation and intelligent control, our loose sand machine delivers a transformative leap in foundry sand processing, setting new industry standards:
Wear-Resistant and Long-Lasting Design:
Our cutting-edge blade features a surface that is meticulously laser-clad with a robust tungsten carbide coating, ranging in thickness from 0.3-0.5mm. This advanced technology ensures a blade lifespan that is an impressive four times longer than that of conventional blades, providing unmatched durability and performance.
The box lining can be upgraded with the superior ARQ wear-resistant steel plate, boasting a remarkable hardness of HB450. This enhancement significantly slashes annual maintenance expenditures by an astonishing 65%, ensuring cost-efficiency and long-term savings.
Energy Consumption Optimization:
Our 55kW permanent magnet synchronous motor, paired with a state-of-the-art variable frequency drive system, achieves a remarkable 25% reduction in electricity usage compared to traditional asynchronous motors, promoting eco-friendly and economical operation.
With our innovative design, the power consumption required to crush a ton of molding sand is a mere ≤0.8kW·h, which represents a dramatic 40% decrease compared to conventional roller crushers, ensuring substantial energy savings.
Quality Improvement Data:
The compaction rate of loosened sand remains impressively steady, fluctuating no more than ≤2%, while the porosity defect rate of castings has been drastically reduced from 3.8% to an outstanding 0.5%, highlighting our commitment to superior quality and precision.
Our system elevates the recycling rate of old sand to a remarkable 95%, while simultaneously slashing the need for new sand by 60%, underscoring our dedication to sustainability and environmental responsibility.
