Product Description
Clay sand, renowned for its outstanding binding capabilities, plays a pivotal role in the molding process, utilizing clay as its primary binder. In the world of foundries, the sand treatment division is of utmost importance, entrusted with supplying premium quality molding sand to the core-making department. The precise preparation of molding sand is crucial, as it significantly influences the quality and efficiency of casting production, boosts output, and dramatically reduces costs. Given the complex and demanding nature of sand treatment operations, handling clay sand treatment and transport presents a considerable workload and challenging environment. Thus, mechanizing the sand treatment process stands as a cornerstone of casting production, ensuring both efficiency and reliability throughout operations.

We offer a full suite of services, including equipment manufacturing, seamless installation, precise commissioning, and comprehensive turnkey project solutions. Rely on us to transform your operations with our innovative expertise and commitment to excellence.
Green sand production line process: Our meticulously crafted process uses clay as a binder to create superior modeling (core) sand. The mechanization of sand recycling is key for optimal efficiency in foundry production. The quality of recovered casting sand post-pouring is crucial for determining the overall quality, production yield, and cost-effectiveness of castings. The intricate process of recycling and treating used sand involves heavy-duty operations and transport under challenging conditions, rendering mechanization indispensable. Upon pouring and cooling, a vibrating shakeout machine (drum shakeout machine) adeptly separates the sand mold, while hot castings are efficiently conveyed to the shot blasting area via a scale conveyor. A strategically positioned belt conveyor at the shakeout machine's sand outlet transports reclaimed sand to the regeneration area. Ingeniously placed suspended magnetic separators and belt conveyors remove iron impurities from the reclaimed sand. Dust is meticulously filtered, and processed sand is stored in compact silos. An innovative boiling cooling bed ensures effective cooling of used sand, which is then elevated via the 2# bucket elevator to the storage silo. The unloader skillfully distributes bulk sand to designated bins, each with vibrating disc feeders. Subsequently, the sand is conveyed to the rotor sand mixer’s storage hopper. Through a sophisticated screw feeder mechanism, coal powder and bentonite are precisely weighed and blended, ensuring uniform mixing in the rotor sand mixer. The resulting refined sand is then ready for subsequent molding, guaranteeing superior casting quality with unmatched precision.
