Product Description
Ingeniously positioned above the sand conveying belt, this revolutionary machine transforms compacted green sand into a loose, workable state post-mixing, ensuring optimal conditions for casting operations.
Our state-of-the-art equipment is a cornerstone of green sand casting mechanized recycling lines. It excels in loosening mixed wet sand and efficiently crushing old sand after separation. Docked with a dust removal system, it elevates the air permeability of molding sand (>80cm³/min) and enhances casting surface quality. As a pivotal element in sand processing, this machine reshapes modern foundry workshops with its potent loosening, robust crushing, and smart dust removal capabilities. Dive deep into our analysis of how this equipment propels foundry companies toward efficient regeneration and eco-friendly production of sand resources, focusing on technological innovations, process adaptability, environmental efficacy, and intelligent control.
1. Process Pain Points and Technological Innovation
Addressing the challenges of wet sand compaction (3-5% water content) and the crushing of old sand with impurities like core bones and iron beans, our loose sand machine achieves breakthroughs with its dual-mode crushing structure and modular design:
Wet Sand Loosening Mode:
Our rotary knife crushing system, featuring 304 stainless steel staggered blades (hardness HRC55-60), slices through sand blocks at 1200r/min, handling 60t/h. This process reduces the bulk density of loosened sand to ≤1.4g/cm³, enhancing air permeability by 40%.
The dynamic screening module, with a built-in Φ8mm grid, synchronously separates large unbroken particles (return rate <2%), ensuring the uniformity of molding sand entering the conveyor belt (particle size standard deviation <0.15mm).
Old Sand Crushing Mode:
Our hammer impact mechanism, with high manganese steel hammers (impact toughness ≥120J/cm²), crushes old sand containing iron beans (diameter ≤20mm) with an efficiency of 45t/h and an iron impurity separation rate of over 98%.
The magnetic pre-separation system, featuring a permanent magnetic roller (magnetic induction strength ≥1500Gs), pre-emptively adsorbs ferromagnetic impurities, reducing the hammer head's wear rate by 70%.
Intelligent Switching Technology:
Effortlessly switch between wet and old sand processing modes with our PLC-controlled one-button system. Conversion takes less than 3 minutes, perfect for both intermittent and continuous production setups.
2. Integrated Solution for Foundry Sand Processing Line
The collaborative synergy between our loose sand machine, conveyor belt, and dust removal system crafts an efficient sand processing ecosystem:
Space Optimization Design:
Innovatively inverted for direct installation over B=800-1400mm belt conveyors, the design boasts a net height of ≤1.2m, reducing vertical space requirements in workshops by 30%.
Standardized inlet and outlet flanges (ISO 5211) allow flawless integration with sand mixers and old sand screening machines (connection error ±2mm).
Easy Maintenance:
Our quick-detachable cutter head and hammer bracket streamline tool replacements to under 20 minutes.
Gas spring-assisted observation windows and inspection doors enable single-person daily maintenance with ease.
3. Core Advantages and Economic Benefits
Through innovative materials and intelligent controls, our loose sand machine propels foundry sand processing into a new era:
Wear-Resistant and Long-Lasting Design:
Our cutting-edge blade surface technology boasts a state-of-the-art laser-clad tungsten carbide coating, with a precise thickness range of 0.3-0.5mm. This advanced coating significantly enhances the blade's durability, extending its lifespan to an impressive four times longer than that of standard blades.
Experience unparalleled cost savings with our innovative box lining replacement, featuring the superior ARQ wear-resistant steel plate with an exceptional hardness rating of HB450. This upgrade dramatically slashes your annual maintenance expenses by an astonishing 65%.
Revolutionary Energy Consumption Optimization:
Our groundbreaking 55kW permanent magnet synchronous motor, coupled with a sophisticated variable frequency drive system, delivers a remarkable 25% reduction in electricity usage compared to traditional asynchronous motors.
Our crusher sets new standards in efficiency, with power consumption for crushing 1 ton of molding sand being a mere ≤0.8kW·h. This represents a remarkable 40% reduction in energy usage compared to conventional roller crushers.
Unprecedented Quality Improvement Data:
Achieve unparalleled precision with our system, where the compaction rate of loosened sand varies by no more than 2%. Additionally, the porosity defect rate in castings is dramatically minimized, plummeting from 3.8% to an extraordinary 0.5%.
Our commitment to sustainability shines with an impressive recycling rate of old sand soaring to 95%, while simultaneously reducing the need for new sand additions by a groundbreaking 60%.
