Product Description
Clay sand, distinguished for its outstanding cohesive properties, is a vital component in the molding arena, where clay serves as the binding agent. In foundries, the sand treatment sector is of paramount importance, as it is responsible for supplying top-tier molding sand to the core-making department. The careful and precise preparation of this sand is crucial because it significantly influences the quality and efficiency of the casting process, boosts production, and slashes costs. Given the complexity and rigor of sand treatment operations, the management of clay sand treatment and its transportation are both labor-intensive and challenging. Thus, automating the sand treatment process is a cornerstone of casting production, ensuring streamlined efficiency and steadfast reliability throughout operations.

Our offering is extensive, providing not only expert equipment manufacturing but also flawless installation, thorough commissioning, and complete turnkey project solutions. Entrust us to revolutionize your operations with our groundbreaking specialization and unmatched proficiency.
Green Sand Production Line Process: Our expertly crafted process utilizes clay as a binding agent to fabricate superior modeling (core) sand. The automation of sand recycling is integral for maximal foundry production efficiency. The caliber of recycled casting sand post-pouring is crucial to the overall quality, production yield, and cost-effectiveness of castings. This intricate process of reclaiming and processing used sand involves robust treatment and transit in tough environmental conditions, underscoring the necessity for automation. Post-pouring and cooling, a vibrating shakeout machine (drum shakeout machine) adeptly partitions the sand mold, while hot castings are seamlessly conveyed to the shot blasting zone via a scale conveyor. A strategically placed belt conveyor at the shakeout machine's sand outlet expertly transports recovered sand to the regeneration area. Ingeniously positioned suspended magnetic separators and belt conveyors efficiently extract iron impurities from the reclaimed sand. Dust is carefully filtered, and processed sand is stored in compact silos. An advanced boiling cooling bed ensures thorough cooling of used sand, which is subsequently elevated via the 2# bucket elevator to the storage silo. The unloader proficiently allocates bulk sand to designated bins, each outfitted with vibrating disc feeders. Subsequently, the sand is conveyed to the rotor sand mixer’s storage hopper. Through an advanced screw feeder system, coal powder and bentonite are precisely weighed and mixed, ensuring homogeneous blending in the rotor sand mixer. The resulting refined sand is then poised for subsequent molding, guaranteeing superior casting quality and precision.
