Product Description
Clay sand, renowned for its unparalleled binding prowess, is an essential component in the art of molding, where clay takes center stage as the binder. In the world of foundries, the sand treatment division is of paramount importance, as it is entrusted with providing top-notch molding sand to the core-making sector. The careful and precise preparation of molding sand is crucial, as it significantly influences the quality and efficiency of casting production, boosts output, and dramatically cuts costs. Given the complex and demanding nature of the sand treatment process, managing clay sand treatment and transport involves a substantial workload under tough conditions. Thus, mechanizing the sand treatment process is a cornerstone of casting production, guaranteeing operational efficiency and reliability.
Qingdao Sanzhuji Technology Co., Ltd. proudly leads the way in crafting innovative clay sand treatment lines. Our all-encompassing services span from the manufacturing of equipment to seamless installation and meticulous commissioning, ultimately delivering comprehensive turnkey project solutions. Rely on us to transform your operations with our groundbreaking expertise.
Green sand production line process: At the heart of our expertly designed process, clay acts as the binder, forming superior modeling (core) sand. The mechanization of sand recycling is paramount for optimal foundry production efficiency. The quality of recovered casting sand post-pouring is a critical factor determining the overall casting excellence, production yield, and cost-effectiveness. The intricate process of recycling and treating used sand involves intensive processing and transportation under challenging conditions, making mechanization indispensable. After pouring and cooling, our advanced vibrating shakeout machine adeptly separates the sand mold, while hot castings are smoothly conveyed to the shot blasting area via a scale conveyor. An intelligently positioned belt conveyor at the shakeout machine's sand outlet transports reclaimed sand to the regeneration area. Ingeniously cross-positioned suspended magnetic separators and belt conveyors extract iron impurities from the reclaimed sand. Dust is meticulously filtered out, and processed sand finds its place in compact silos. Our state-of-the-art boiling cooling bed ensures thorough cooling of used sand, subsequently elevated via the 2# bucket elevator to the storage silo. The unloader skillfully allocates bulk sand to designated bins, each with vibrating disc feeders. The sand is then conveyed to the rotor sand mixer’s storage hopper. Through a sophisticated screw feeder system, coal powder and bentonite are precisely measured and blended, ensuring homogeneous mixing in the rotor sand mixer. The resultant refined sand is primed for subsequent molding, promising superior casting quality with unrivaled precision.
