Unveiling the pinnacle of innovation with the S53 Scrubber Recycling Machine—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.
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.
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 high speeds (720-970r/min). These shafts feature wear-resistant alloy blades. As sand enters the chamber, it is subjected to repeated rubbing and collision, removing the resin film and achieving surface rounding.
2. Boiling airflow assists film stripping: The bottom blower, with air volume exceeding 3700m³/h, creates a fluidized environment. This airflow heightens particle collision and facilitates the expulsion of detached film and dust, elevating the stripping rate to over 80%.
3. Wear-resistant and vibration-reducing design: The rubbing blade employs the carbide convex rib welding process, enhancing wear resistance threefold. The chamber body uses rubber elasticity connections to mitigate vibration.
4. Applicable sand mold and regeneration effect:
- Furan resin sand: Resin film effectively removed, tensile strength restored to 90%.
- Water glass sand: Dry regeneration as a pretreatment significantly reduces subsequent wet load.
- Alkali phenolic resin sand: Improved roundness and 30% reduction in gas emissions.
5. Technical advantages and economy: The dual-axis machine reduces unit energy consumption by 40% compared to conventional centrifugal machines. It maintains a crushing rate under 5% and reduces curing agent usage by 30%-50% during subsequent sand mixing processes.
Frequently Asked Questions
