Product Description
Clay sand, celebrated for its exceptional binding capabilities, serves as an indispensable element in the molding process, utilizing clay as its binder. Within the realm of foundries, the sand treatment division holds immense significance, tasked with delivering superior quality molding sand to the core-making department. The precise and meticulous preparation of molding sand is pivotal, as it profoundly impacts the excellence and efficiency of casting production, enhances output, and significantly reduces costs. Given the intricate and demanding nature of sand treatment processes, handling clay sand treatment and transportation involves substantial workload and challenging conditions. Therefore, mechanizing the sand treatment process is a fundamental pillar of casting production, ensuring both efficiency and reliability across operations.
Qingdao Sanzhuji Technology Co., Ltd. stands as a trailblazer in the design and implementation of cutting-edge clay sand treatment lines. We provide a comprehensive suite of services that cover equipment manufacturing, seamless installation, meticulous commissioning, and complete turnkey project solutions. Trust us to elevate your operations with our pioneering expertise.
Green sand production line process: Our meticulously designed process employs clay as a binder to create superior modeling (core) sand. The mechanization of sand recycling is crucial for achieving optimal efficiency in foundry production. The quality of recovered casting sand after pouring is a vital determinant of the overall quality, production yield, and cost-effectiveness of castings. The complex process of recycling and treating used sand involves heavy duty processing and transportation under challenging environmental conditions, making mechanization essential. After pouring and cooling, a vibrating shakeout machine (drum shakeout machine) skillfully separates the sand mold, while hot castings are efficiently transported to the shot blasting area via a scale conveyor. A strategically placed belt conveyor at the shakeout machine's sand outlet transfers reclaimed sand to the regeneration area. Cross-placed suspended magnetic separators and belt conveyors ingeniously remove iron impurities from the reclaimed sand. Dust is meticulously filtered out, and processed sand is stored in small silos. A cutting-edge boiling cooling bed ensures effective cooling of used sand, which is then elevated via the 2# bucket elevator to the storage silo. The unloader expertly distributes bulk sand to designated bins, each equipped 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.
