Product Description
Clay sand, renowned for its remarkable binding prowess, is an essential component in the molding process, utilizing clay as its binder. Within foundries, the sand treatment division plays a critical role, tasked with delivering top-tier molding sand to the core-making department. The accurate and thorough preparation of molding sand is pivotal, as it dramatically influences the excellence and efficiency of casting production, boosts output, and substantially lowers costs. Given the intricate and demanding nature of sand treatment processes, handling clay sand treatment and transportation involves a significant workload and challenging conditions. Thus, mechanizing the sand treatment process is a fundamental pillar of casting production, ensuring both operational efficiency and reliability.
Qingdao Sanzhuji Technology Co., Ltd. is a trailblazer in the design and implementation of state-of-the-art clay sand treatment lines. We offer a holistic suite of services encompassing equipment manufacturing, seamless installation, precise commissioning, and comprehensive turnkey project solutions. Entrust us to elevate your operations to new heights with our pioneering expertise.
Green sand production line process: Our meticulously crafted process employs clay as a binder to create top-quality modeling (core) sand. The mechanization of sand recycling is crucial for attaining peak efficiency in foundry production. The quality of reclaimed casting sand post-pouring is a critical determinant of 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 indispensable. After pouring and cooling, a vibrating shakeout machine (drum shakeout machine) expertly 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 conveys the 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, with processed sand being 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 meticulously distributes bulk sand to designated bins, each equipped with vibrating disc feeders. Subsequently, the sand is transferred to the rotor sand mixer’s storage hopper. Through a sophisticated screw feeder mechanism, coal powder and bentonite are precisely weighed and blended, ensuring homogeneous mixing in the rotor sand mixer. The resulting refined sand is then primed for subsequent molding, guaranteeing superior casting quality with unparalleled precision.
