Product Description
Poised gracefully above the sand conveying belt, our advanced Aerator and Sand Cutter masterfully transforms dense green sand into a free-flowing, loose state post-mixing, setting the stage for exceptional casting results.
Within the heart of the green sand casting mechanized recycling line, our formidable machine revitalizes wet sand, expertly disintegrating it and ensuring old sand, post-separation, is finely crushed. This precision process is vital for maintaining superior air permeability of molding sand (>80cm³/min) and impeccable casting surface quality. As the linchpin of the sand processing system, this sand loosening machine revolutionizes modern foundry operations with its robust loosening prowess, efficient crushing capabilities, and intelligent dust removal functionality. In this comprehensive article, we delve deep into the transformative role of this machine, exploring how it empowers foundry enterprises to achieve outstanding regeneration and pristine production of sand resources through the lenses of technological innovation, process adaptability, environmental impact, and smart control.
1. Process Pain Points and Technological Innovation
Addressing challenges like the compaction of wet sand (3-5% water content) after mixing and the intricate demands of old sand crushing (with core bone and iron impurities), our loose sand machine pioneers breakthrough technologies with its dual-mode crushing structure and innovative modular design:
Wet Sand Loosening Mode:
Our state-of-the-art Rotary Knife Crushing System employs an exquisite group of staggered blades made from 304 stainless steel (hardness HRC55-60) to effortlessly slice through sand blocks at 1200r/min. Boasting an impressive processing capacity of 60t/h, it achieves a bulk density for loosened molding sand of ≤1.4g/cm³, enhancing air permeability by a remarkable 40%.
Dynamic Screening Module: Featuring a built-in Φ8mm aperture grid, this module synchronously segregates any unbroken large particles, maintaining a return rate of <2%, ensuring the molding sand's uniformity on the conveyor belt (achieving a particle size standard deviation of <0.15mm).
Old Sand Crushing Mode:
The Hammer Impact Mechanism, outfitted with a high manganese steel hammer head (impact toughness ≥120J/cm²), is designed to demolish old sand groups embedded with iron beans (up to 20mm diameter), with an impeccable crushing efficiency of 45t/h and an outstanding iron impurity separation rate of >98%.
Magnetic Pre-separation: A cutting-edge permanent magnetic roller (magnetic induction strength ≥1500Gs) efficiently pre-adsorbs ferromagnetic impurities, drastically reducing the hammer head wear rate by an impressive 70%.
Intelligent Switching Technology:
Seamlessly switch between wet and old sand processing modes with the touch of a button through our sophisticated PLC control system, achieving conversion in under three minutes, ideal for both intermittent and continuous production line setups.
2. Integrated Solution for Foundry Sand Processing Line
The synchronized operation of the loose sand machine, conveyor belt, and dust removal system constructs a high-efficiency sand processing ecosystem, redefining productivity and effectiveness.
Space Optimization Design:
Ingeniously adopting an inverted installation configuration, it stands elegantly over the B=800-1400mm belt conveyor, with a streamlined net height of ≤1.2m, resulting in a commendable 30% vertical space savings within the workshop.
The precisely engineered standard design of the inlet and outlet flanges (compliant with ISO 5211) ensures a flawless connection with both the sand mixer and the old sand screening machine, maintaining a connection error of just ±2mm.
Easy Maintenance:
With our quick-detachable cutter head and hammer bracket design, tool replacement is a breeze, taking no more than 20 minutes to complete.
The inclusion of a gas spring-assisted observation window and inspection door facilitates easy, single-person daily maintenance.
3. Core Advantages and Economic Benefits
By leveraging material innovation and intelligent control, the loose sand machine propels foundry sand processing to unparalleled heights, delivering extraordinary advantages and economic benefits to enterprises.
Durable and Robust Construction for Lasting Performance:
Featuring a cutting-edge laser-cladding process, our blade surface is coated with tungsten carbide (0.3-0.5mm thick), multiplying its durability by four times compared to conventional blades.
With an option to upgrade the box lining to ARQ wear-resistant steel plate (hardness HB450), experience a remarkable 65% reduction in annual maintenance expenses.
Innovative Energy Efficiency for Cost Savings:
Equipped with a state-of-the-art 55kW permanent magnet synchronous motor and a variable frequency drive system, our solution conserves 25% more electricity than traditional asynchronous motor setups.
Achieve power consumption efficiency with our design, crushing 1 ton of molding sand using ≤0.8kW·h – a significant 40% reduction compared to conventional roller crushers.
Enhanced Quality Control for Superior Output:
Our advanced system ensures the compaction rate of loosened sand remains within ≤2%, while dramatically reducing the porosity defect rate of castings from 3.8% to just 0.5%.
Optimize sustainability with a 95% recycling rate of old sand, decreasing the need for new sand additions by an impressive 60%.
