Product Description
Clay sand, renowned for its superior binding properties, plays a vital role in the molding process by utilizing clay as its binder. Within the esteemed realm of foundries, the sand treatment division holds paramount importance, dedicated to providing top-tier molding sand to the core-making department. The meticulous preparation of molding sand is crucial, significantly influencing the quality and efficiency of casting production, enhancing output, and substantially lowering costs. Given the complex and demanding nature of sand treatment processes, managing clay sand treatment and transportation involves considerable workload and challenging conditions. Therefore, mechanizing the sand treatment process is an essential cornerstone of casting production, ensuring both efficiency and reliability across operations.
Qingdao Sanzhuji Technology Co., Ltd. is a pioneering leader in the design and implementation of state-of-the-art clay sand treatment lines. Our comprehensive suite of services encompasses equipment manufacturing, seamless installation, precise commissioning, and complete turnkey project solutions. Trust our expertise to elevate your operations to new heights of efficiency and innovation.
Green Sand Production Line Process: Our meticulously engineered process employs clay as a binder to create superior modeling (core) sand. The mechanization of sand recycling is instrumental in achieving optimal efficiency in foundry production. The quality of recovered casting sand after pouring is a critical 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 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 skillfully transfers reclaimed sand to the regeneration area. Cross-placed suspended magnetic separators and belt conveyors ingeniously eliminate iron impurities from the reclaimed sand. Dust is meticulously filtered out, and processed sand is stored in strategically located 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 and consistency.
