Product Description
Clay sand, renowned for its superior binding properties, is an essential component in the molding process, utilizing clay as an effective binder. In the world of foundries, the sand treatment division holds paramount importance, entrusted with delivering top-tier molding sand to the core-making department. The precise and meticulous preparation of molding sand is crucial, as it directly influences the excellence and efficiency of casting production, boosts output, and drastically reduces costs. Given the intricate and demanding nature of sand treatment processes, managing clay sand treatment and transportation involves a substantial workload and challenging conditions. Thus, mechanizing the sand treatment process is a cornerstone of casting production, ensuring both efficiency and reliability throughout operations.
Qingdao Sanzhuji Technology Co., Ltd. is a pioneer in designing and implementing state-of-the-art clay sand treatment lines. We offer an all-encompassing range of services that include equipment manufacturing, seamless installation, meticulous commissioning, and comprehensive turnkey project solutions. Entrust us to enhance your operations with our trailblazing expertise and experience.
Green sand production line process: Our expertly crafted process leverages clay as a binder to produce superior modeling (core) sand. The mechanization of sand recycling is crucial for achieving peak efficiency in foundry production. The quality of reclaimed casting sand after pouring is a critical factor in determining 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 conditions, making mechanization indispensable. After pouring and cooling, a vibrating shakeout machine (drum shakeout machine) deftly separates the sand mold, while hot castings are efficiently transported to the shot blasting area via a scale conveyor. A strategically positioned belt conveyor at the shakeout machine's sand outlet deftly transfers reclaimed sand to the regeneration area. Ingenious cross-placed suspended magnetic separators and belt conveyors efficiently remove iron impurities from the reclaimed sand. Dust is meticulously filtered out, with processed sand stored in small silos. An advanced boiling cooling bed effectively cools 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 measured 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 unparalleled precision.
