Product Description
Unveiling the pinnacle of innovation with the S53 Scrubber Recycling Machine from Qingdao Sanzhuji Technology Co., Ltd.—an extraordinary leap in the world of sand grain rejuvenation. This cutting-edge machine is equipped with a powerful double-axis mechanism that masterfully eradicates the stubborn resin curing agent clinging to the surface of sand grains. Through its dynamic rubbing and advanced de-filming processes, it ensures thorough sand regeneration.
Elevate your efficiency with our state-of-the-art machine, whose base is thoughtfully equipped with a high-performance fan designed to meticulously extract residual old film and dust, culminating in immaculate cleanliness. Post-treatment, the rejuvenated sand showcases exceptional integrity and beautifully rounded grains, greatly minimizing the necessity for additional liquid materials in the subsequent mixing phase. This not only enhances cost-effectiveness but also streamlines your operations. Welcome the future of sand recycling with the exceptional S53 Scrubber Recycling Machine.
As the pivotal component in the regeneration of foundry old sand, this formidable rubbing regeneration machine achieves the efficient stripping and renewal of old sand types such as resin sand and water glass sand. This is accomplished through the harmonious synergy of dual-axis mechanical rubbing and airflow assistance. Below, explore a comprehensive analysis detailing the technical principles, structural design, process flow, and real-world application outcomes:
1. Technical principles and core mechanisms
The dual-axis regeneration machine is engineered with two sets of transmission main shafts that rotate in opposite directions at incredibly high speeds (ranging from 720-970r/min). These shafts feature wear-resistant alloy blades or cast iron rubbing discs. As sand enters the regeneration chamber, it is subjected to repeated rubbing and collision under the linear shear force and convection of these blades. This mechanical process not only effectively removes the resin film and curing agent from the sand's surface but also achieves surface rounding by friction between sand particles, thereby reducing edge damage. Compared to traditional three-axis structures, this dual-axis design optimizes chamber space, enhances material throughput by an impressive 10-30t/h, and simultaneously reduces energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, boasting an air volume exceeding 3700m³/h, injects adjustable airflow into the chamber via the boiling orifice plate to create a fluidized environment where sand and air intermingle. This airflow not only heightens the collision frequency between sand particles but also facilitates the expulsion of detached inert film and dust through the dust removal vent. This 'mechanical + airflow' dual effect elevates the film stripping rate to over 80%, while the sand temperature is reduced by a substantial 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade employs the carbide convex rib welding process, significantly enhancing wear resistance by more than threefold. The chamber body and frame are connected via rubber elasticity to effectively mitigate the vibration induced by high-speed operations, thereby ensuring the equipment's stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: In just 180 seconds of rubbing, the brittle resin film is effectively removed, with burning loss maintained at less than 1.0%. The tensile strength of the regenerated sand is restored to 90% of that of new sand.
Water glass sand: When paired with wet regeneration (sand-water ratio 1:1.5) or a low-temperature freezing centrifugal process (-40ºC), the dry regeneration method as a pretreatment significantly reduces the subsequent wet load.
Alkali phenolic resin sand: The robust film demands higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of sand particles is visibly improved, and gas emissions are reduced by an impressive 30%.
5. Technical advantages and economy
Revolutionized regeneration efficiency. Compared to conventional centrifugal regeneration machines (power 22kW/stage) or air flow impact equipment, the dual-axis regeneration machine reduces unit energy consumption by a remarkable 40%. It maintains a sand particle crushing rate of under 5%, delivering integrity superior to that of vibration regeneration techniques.
In the quest for production cost optimization, our innovative Customized Mechanical Rubbing Solutions for Coated Sand Regeneration by Qingdao Sanzhuji Technology Co., Ltd. stand out as a beacon of efficiency. The minimized resin active film residue on regenerated sand, kept impressively below 0.3%, allows for a remarkable reduction in curing agent usage by 30%-50% during sand mixing processes. Moreover, the sand-iron ratio is ingeniously decreased from 1:1 to a cost-effective 1:1.5. Together, these advancements drastically diminish the necessity for purchasing new sand, streamlining both expenses and resource use.
Our commitment to environmental stewardship is exemplified through the exceptional compatibility of our dry regeneration process, which operates without wastewater discharge. The cutting-edge pulse back-blowing dust removal system ensures over 99% dust removal efficiency, meticulously processing dust and aligning with the stringent ultra-low emission standards demanded by the foundry industry. This eco-friendly approach not only upholds industry compliance but also champions a sustainable future, reflecting Qingdao Sanzhuji Technology Co., Ltd.'s dedication to eco-conscious innovation.
