Product Description
Unveiling the cutting-edge S53 Scrubber Recycling Machine, an extraordinary innovation by Qingdao Sanzhuji Technology Co., Ltd. This state-of-the-art equipment revolutionizes sand grain rejuvenation with its powerful double-axis mechanism, meticulously removing the resin curing agent from sand surfaces through dynamic rubbing and advanced de-filming processes.
Engineered for superior performance, the machine's foundation is equipped with a high-efficiency fan that deftly separates residual old film and dust, ensuring impeccable cleanliness. Post-treatment, the revitalized sand exhibits remarkable integrity with beautifully rounded grains. This elevated quality reduces the need for additional liquid materials in subsequent mixing, presenting a more cost-effective and streamlined process. Embark on a new era of sand recycling excellence with the S53 Scrubber Recycling Machine.
As the pivotal machinery for foundry sand regeneration, this robust rubbing regeneration machine achieves efficient stripping and renewal of old sand such as resin sand and water glass sand. It leverages the combined power of dual-axis mechanical rubbing and airflow assistance. Below is a comprehensive examination covering technical principles, structural design, process flow, and real-world application outcomes:
1. Technical principles and core mechanisms
The dual-axis regeneration machine features two main transmission shafts rotating at high speeds (720-970r/min) in opposite directions, with wear-resistant alloy blades or cast iron rubbing discs mounted on the shafts. As sand enters the regeneration chamber, it undergoes continuous rubbing and collision due to the linear shear force and blade convection. This mechanical action efficiently strips the resin film and curing agent from sand surfaces while achieving particle rounding through inter-sand friction, minimizing edge wear. Compared to traditional three-axis structures, the dual-axis design optimizes chamber space, boosts material throughput by 10-30t/h, and concurrently lowers energy consumption.
2. Boiling airflow assists film stripping. The bottom blower, with an air volume exceeding 3700m³/h, channels adjustable airflow into the chamber via a boiling orifice plate, creating a fluidized sand-air mixing environment. This airflow enhances sand particle collision frequency and facilitates the discharge of detached inert film and dust through the dust removal vent. The combined "mechanical + airflow" effect elevates film stripping rates beyond 80%, while reducing 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 3 times. The chamber body and frame are elastically connected with rubber to effectively mitigate high-speed operation-induced vibrations, ensuring equipment stability.
4. Applicable sand mold and regeneration effect
Furan resin sand: The fragile resin film is removed within 180 seconds of rubbing, with burning loss remaining below 1.0%. The tensile strength of regenerated sand is restored to 90% of new sand.
Water glass sand: Requires integration with wet regeneration (sand-water ratio 1:1.5) or low-temperature freezing centrifugal processing (-40ºC). Dry regeneration serves as an effective pretreatment, reducing the subsequent wet load.
Alkali phenolic resin sand: Demands higher rubbing strength, potentially using wheel rolling pressurization. Post-regeneration, the sand particle roundness is improved, and gas emissions are reduced by 30%.
5. Technical advantages and economy
Enhanced regeneration efficiency. Compared to traditional centrifugal regeneration machines (power 22kW/stage) or airflow impact equipment, the double-axis regeneration machine reduces unit energy consumption by 40%, controls sand particle crushing rates within 5%, and maintains better integrity than vibration regeneration.
Optimize your production costs like never before! Our innovative process ensures that the resin active film residue of regenerated sand remains below 0.3%. This efficiency enables a remarkable reduction in the curing agent required by 30% to 50% during the sand mixing process. Moreover, our advanced methodology transforms the traditional sand-iron ratio from 1:1 to a more economical 1:1.5. This transformation leads to a significant decrease in the costs associated with purchasing new sand, making your operations more cost-effective and profitable.
Achieve unparalleled environmental compatibility with our cutting-edge dry regeneration process, which operates without any wastewater discharge. Our system's dust is meticulously managed through a state-of-the-art pulse back-blowing dust removal system, boasting an impressive dust removal efficiency greater than 99%. This system not only meets but exceeds the ultra-low emission standards required in the foundry industry, positioning your operations at the forefront of environmentally sustainable practices.
