Product Description
Clay sand, renowned for its superb binding qualities, is an essential component in the molding process, utilizing clay as its binder. In the dynamic world of foundries, the sand treatment division plays a crucial role, tasked with delivering top-tier molding sand to the core-making department. The meticulous preparation of molding sand is critical, as it greatly influences the quality and efficiency of casting production, enhances output, and substantially minimizes costs. Given the complex and demanding nature of sand treatment processes, managing clay sand treatment and transportation involves significant workload and challenging conditions. Consequently, mechanizing the sand treatment process is a cornerstone of casting production, ensuring both efficiency and reliability across operations.
Qingdao Sanzhuji Technology Co., Ltd. is a leader in the design and implementation of state-of-the-art clay sand treatment lines. We offer a full spectrum of services that include equipment manufacturing, seamless installation, precise commissioning, and comprehensive turnkey project solutions. With our pioneering expertise, trust us to elevate your operations to new heights.
Green sand production line process: Our meticulously designed process expertly utilizes clay as a binder to create superior modeling (core) sand, central to achieving maximum efficiency in foundry production. The quality of recovered casting sand post-pouring is crucial to determining overall quality, production yield, and cost-effectiveness of castings. The intricate process of recycling and treating used sand involves heavy-duty processing and transportation under challenging environmental conditions, underscoring the necessity of mechanization. After pouring and cooling, a vibrating shakeout machine (drum shakeout machine) deftly separates the sand mold, while hot castings are transported seamlessly to the shot blasting area via a scale conveyor. A strategically placed belt conveyor at the shakeout machine's sand outlet channels reclaimed sand to the regeneration area. Ingeniously designed cross-placed suspended magnetic separators and belt conveyors remove iron impurities from the reclaimed sand. Dust is meticulously filtered out, and processed sand is stored in compact silos. A cutting-edge boiling cooling bed ensures the 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 primed for subsequent molding, guaranteeing superior casting quality with unparalleled precision.
