Product Description
Clay sand is celebrated for its exceptional binding capabilities, making it an indispensable element in molding operations where clay acts as the binder. Within the foundry, the sand treatment section is pivotal, entrusted with the crucial task of supplying the molding core-making department with high-caliber molding sand. The meticulous crafting of this molding sand is a key determinant of casting excellence, greatly enhancing production output while minimizing costs. Owing to the complex nature of sand treatment, the processes associated with the treatment and transportation of clay sand are extensive and labor-intensive, often conducted under strenuous conditions. The mechanization of these sand treatment processes is therefore vital, serving as a foundational pillar in casting production that guarantees efficiency and reliability.
Qingdao Sanzhuji Technology Co., Ltd. stands as a vanguard in the conceptualization and implementation of clay sand treatment lines. The company offers an all-encompassing suite of services that includes equipment manufacturing, installation, commissioning, and the execution of complete turnkey projects.
Green Sand Production Line Process: Our expertly devised process leverages clay as a binder to produce superior modeling (core) sand. The mechanization of sand recycling is instrumental in facilitating high-efficiency foundry production. The quality of casting sand, once recovered post-pouring, plays a significant role in determining the integrity, yield, and cost-effectiveness of castings. The recycling and treatment of used sand are complex operations, involving heavy processing and transport under challenging environmental conditions, making mechanization indispensable. Post-pouring and cooling, our advanced vibrating shakeout machine (drum shakeout machine) adeptly disintegrates the sand mold, while hot castings are seamlessly conveyed to the shot blasting section via a precision scale conveyor. A strategically placed belt conveyor at the shakeout machine's sand outlet efficiently transports reclaimed sand to the regeneration area. Cross-arranged suspended magnetic separators and belt conveyors skillfully extract iron impurities from the reclaimed sand. Dust is meticulously filtered, and the treated sand is stored in small silos. Our cutting-edge boiling cooling bed facilitates effective cooling of used sand, which is then hoisted by the 2# bucket elevator to the storage silo. The unloader precisely allocates bulk sand to designated bins, each equipped with vibrating disc feeders. The sand is then directed to the rotor sand mixer’s storage hopper. Through an advanced screw feeder mechanism, coal powder and bentonite are meticulously weighed and combined, ensuring a consistent mix in the rotor sand mixer. This refined sand is primed for subsequent molding, guaranteeing superior casting outcomes.
