Product Description
Clay sand, a vital molding material using clay as its binder, plays an indispensable role in the foundry industry. The sand treatment department stands as a cornerstone, tasked with delivering premium molding sand to the core-making section. The preparation of this sand is pivotal, influencing casting quality, boosting efficiency, and reducing costs. Given the intricate processes involved, along with the significant workload and challenging conditions, mechanizing the sand treatment process is crucial for optimizing casting production.
Qingdao Sanzhuji Technology Co., Ltd. offers end-to-end solutions for clay sand treatment lines. From initial design to equipment manufacturing, installation, and commissioning, our turnkey projects ensure seamless integration and superior performance.
Green sand production line process: Clay sand, utilizing clay as a binder, forms the backbone of foundry production via mechanized recovery processes. The casting sand's quality, post-pouring, is essential for maintaining superior production standards, optimizing output, and minimizing costs. Handling used sand's complex treatment and logistics is demanding, thus necessitating mechanization. Post-cooling, sand molds are efficiently separated by a vibrating shakeout machine. The hot castings journey to a shot blasting area via a conveyor, while the shakeout machine's sand outlet employs a belt conveyor for old sand transport to the regeneration zone. Here, a suspended magnetic separator works in tandem with a belt conveyor to extract iron impurities. Dust is expertly removed, and the screened sand transitions to a small silo, cooled by a boiling bed, and lifted by a bucket elevator for storage. The unloader adeptly allocates old sand among bins, with a vibrating disc feeder ensuring smooth transfer to a mixer. Additives like coal powder and bentonite are precisely measured and incorporated, culminating in the rotor sand mixer for a well-proportioned blend, ready for the next molding cycle.
