Product Description
Presenting the cutting-edge S53 Scrubber Recycling Machine from Qingdao Sanzhuji Technology Co., Ltd.—a true innovation in the realm of sand grain restoration. This exceptional machine harnesses a powerful double-axis mechanism crafted to expertly eradicate the resin curing agent that clings to sand grain surfaces. Through dynamic rubbing and advanced de-filming processes, it rejuvenates sand with unparalleled precision.
Unleashing optimal efficiency, the machine's base is strategically equipped with a high-performance fan, meticulously crafted to expertly extract residual old film and dust, resulting in immaculate cleanliness. Post-treatment, the rejuvenated sand emerges with unmatched integrity and exquisitely rounded grains. This superior quality notably reduces the need for additional liquid materials during subsequent mixing, offering a more economically and operationally efficient solution. Discover the next generation of sand recycling with the S53 Scrubber Recycling Machine.
As the pinnacle equipment for revitalizing foundry old sand, this formidable rubbing regeneration machine flawlessly executes efficient stripping and rejuvenation of old sand types such as resin sand and water glass sand. This is achieved through the harmonious integration of dual-axis mechanical rubbing and airflow assistance. Below is an in-depth examination covering technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The dual-axis regeneration machine utilizes two sets of main transmission shafts rotating in opposing high-speed directions (achieving speeds of 720-970r/min). These shafts are fitted with wear-resistant alloy blades or cast iron rubbing discs. Upon entering the regeneration chamber, the sand is subjected to repeated rubbing and collision under the linear shear force and convection created by the blades. This mechanical action not only efficiently strips away the resin film and curing agent from the sand surface but also accomplishes surface rounding through inter-sand particle friction, minimizing edge damage. Compared to traditional three-axis systems, the dual-axis design optimally enhances chamber space, increases material throughput by 10-30t/h, and simultaneously reduces energy consumption.
2. Boiling airflow assists film stripping. A bottom blower (air volume > 3700m³/h) ingeniously injects adjustable airflow into the chamber via a boiling orifice plate, crafting a fluidized sand and air mixing environment. This airflow amplifies collision frequency among sand particles and facilitates the expulsion of detached inert film and dust through the dust removal vent. This synergistic 'mechanical + airflow' dual effect elevates the film stripping rate to over 80%, while also reducing sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade features a carbide convex rib welding process, tripling wear resistance. The chamber body and frame are interconnected by rubber elasticity, effectively dampening vibrations resulting from high-speed operation and ensuring equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The brittle resin film is meticulously removed through rubbing within 180 seconds. The burning loss remains under 1.0%, with the regenerated sand's tensile strength being restored to 90% of new sand.
Water glass sand: Requires collaboration with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal processes (-40ºC). However, dry regeneration as a pretreatment can significantly lessen the subsequent wet load.
Alkali phenolic resin sand: With its tough film necessitating greater rubbing strength (e.g., wheel rolling pressurization), the sand particles' roundness improves post-regeneration, reducing gas emissions by 30%.
5. Technical advantages and economy
The regeneration efficiency is remarkably enhanced. In comparison to traditional centrifugal regeneration machines (power 22kW/stage) or airflow impact equipment, the dual-axis regeneration machine reduces unit energy consumption by 40%. Moreover, the sand particle crushing rate is contained within 5%, delivering greater integrity than vibration regeneration methods.
Our groundbreaking approach to production cost optimization unveils the remarkable potential of our innovative Factory Customization for Mechanical Rubbing of Coated Sand Solutions. Witness the transformation as the resin active film residue in regenerated sand, remaining below 0.3%, empowers you to slash the curing agent usage by an astounding 30%-50% during the sand mixing process. Furthermore, experience a cost reduction like never before as the sand-iron ratio is expertly adjusted from 1:1 to a more economical 1:1.5, dramatically cutting down the expenditure on purchasing fresh sand.
Embrace the future of sustainable manufacturing with our unparalleled commitment to environmental compatibility. Our cutting-edge dry regeneration process eliminates wastewater discharge, ensuring a greener tomorrow. Coupled with our advanced pulse back-blowing dust removal system, boasting an exceptional dust removal efficiency of over 99%, our solution not only meets but exceeds the stringent ultra-low emission standards of the foundry industry.
