Product Description
Introducing the cutting-edge S53 Scrubber Recycling Machine by Qingdao Sanzhuji Technology Co., Ltd., a true marvel in sand grain rejuvenation. This state-of-the-art machine features a robust double-axis mechanism that masterfully eliminates the resin curing agent lingering on the surface of sand grains through dynamic rubbing and sophisticated de-filming processes. Harness the power of innovation as this machine transforms sand recycling into a seamless, efficient endeavor.
Enhancing its remarkable efficiency, the machine's foundation is ingeniously equipped with a high-performance fan that diligently separates residual old film and dust, ensuring absolute cleanliness. After undergoing this meticulous treatment, the rejuvenated old sand boasts an extraordinary level of integrity and exquisitely rounded grains. This superior quality significantly reduces the necessity for additional liquid materials during subsequent mixing, paving the way for an even more cost-effective and efficient process. Embrace the future of sand recycling with the S53 Scrubber Recycling Machine, where innovation meets sustainability.
As the pivotal core of foundry old sand regeneration, the powerful strong rubbing regeneration machine achieves the efficient stripping and renewal of old sand, such as resin and water glass sand, through the synergistic effects of dual-axis mechanical rubbing and airflow assistance. Explore a comprehensive analysis encompassing technical principles, structural design, process flow, and real-world application effects:
1. Technical principles and core mechanisms
The revolutionary dual-axis regeneration machine utilizes two sets of transmission main shafts rotating in opposite directions at high speed (capable of reaching 720-970r/min). On these shafts are mounted wear-resistant alloy blades or cast iron rubbing discs. As sand enters the regeneration chamber, it undergoes repeated rubbing and collision under the linear shear force and convection of the blades. This mechanical action not only strips the resin film and curing agent from the sand surface but also achieves surface rounding through the friction between sand particles, thereby reducing edge damage. Compared with the traditional three-axis structure, the dual-axis design optimizes chamber space, elevates material throughput by 10-30t/h, and simultaneously diminishes energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, with an impressive air volume exceeding 3700m³/h, injects adjustable airflow into the chamber through the boiling orifice plate to form a fluidized environment of sand and air mixing. This dynamic airflow not only enhances the collision frequency between sand particles but also facilitates the discharge of detached inert film and dust through the dust removal vent. This ingenious "mechanical + airflow" dual effect boosts the film stripping rate to an impressive 80% or more, while simultaneously reducing the sand temperature by 30-50ºC.
3. Wear-resistant and vibration-reducing design. The rubbing blade employs a carbide convex rib welding process, enhancing wear resistance by over three times. Meanwhile, the chamber body and frame are connected by rubber elasticity to effectively suppress the vibration caused by high-speed operation, ensuring unparalleled equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The delicate resin film can be removed by rubbing for 180 seconds. The burning loss is minimized to less than 1.0%, and the tensile strength of the regenerated sand is restored to an impressive 90% of the new sand's original strength.
Water glass sand: Combines with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal process (-40ºC) for optimal results. However, dry regeneration as a pretreatment step effectively reduces the subsequent wet load, promising a streamlined operation.
Alkali phenolic resin sand: This tough film demands higher rubbing strength, such as wheel rolling pressurization. Post-regeneration, the roundness of sand particles is significantly improved, with gas emission reduced by an impressive 30%.
5. Technical advantages and economy
The regeneration efficiency is remarkably improved. Compared with traditional centrifugal regeneration machines (power 22kW/stage) or air flow impact equipment, the unit energy consumption of the double-axis regeneration machine is reduced by a significant 40%. Furthermore, the sand particle crushing rate is controlled within 5%, ensuring superior integrity compared to vibration regeneration methods.
Experience unmatched production cost optimization with our Comprehensive Services for Mechanical Rubbing and Coated Sand Solutions. Our innovative process ensures that the resin active film residue of the regenerated sand is kept below 0.3%. This allows for a substantial reduction in the curing agent required—up to an impressive 30%-50% less—while mixing sand. Additionally, we streamline your operations by adjusting the sand-iron ratio from 1:1 to a more efficient 1:1.5, leading to a dramatic decrease in the need for new sand purchases, ultimately slashing your overall production costs.
Champion environmental responsibility with our state-of-the-art solutions that prioritize environmental compatibility. Implementing a dry regeneration process ensures there is no wastewater discharge, aligning perfectly with green practices. Our cutting-edge pulse back-blowing dust removal system efficiently centralizes and processes any dust, achieving a remarkable dust removal efficiency greater than 99%. This system supports ultra-low emission standards, setting a new benchmark for eco-friendliness in the foundry industry while meeting and exceeding all regulatory requirements.
