Product Description
Clay sand, celebrated for its exceptional binding capabilities, seamlessly integrates into molding operations, utilizing clay as a natural binder. Within the foundry, the sand treatment division emerges as a crucial entity, entrusted with the provision of superior quality molding sand to the molding core-making department. The precise formulation of molding sand holds significant sway over the caliber of casting outputs, elevating production efficacy while curbing expenditures. Given the complexity inherent in sand treatment methodologies, the workload involved in clay sand treatment and transit is substantial, presenting challenging conditions. Therefore, the mechanization of the sand treatment process is paramount, serving as the linchpin of casting production, delivering both efficiency and steadfast dependability.
Qingdao Sanzhuji Technology Co., Ltd. commands leadership in the innovative design and delivery of clay sand treatment lines, offering an all-encompassing suite of services, including equipment manufacturing, meticulous installation, precise commissioning, and flawlessly executed turnkey projects.
Green sand production line process: Our precisely orchestrated process artfully employs clay as a binder to meticulously create modeling (core) sand. The mechanization of sand recycling is indispensable for optimizing foundry operations. The quality of recuperated casting sand post-pouring critically impacts the overall excellence, yield, and cost-effectiveness of castings. The sophisticated process of recycling and treating used sand involves extensive processing and transportation under demanding environmental conditions, making mechanization essential. Following pouring and cooling, a vibrating shakeout machine (drum shakeout machine) adeptly disintegrates the sand mold, while hot castings are effortlessly conveyed to the shot blasting area via a scale conveyor. A strategically positioned belt conveyor at the shakeout machine's sand outlet channels reclaimed sand to the regeneration area. Cross-placed suspended magnetic separators and belt conveyors skillfully extract iron impurities from the reclaimed sand. Dust is rigorously filtered, and processed sand is stored in specialized small silos. A cutting-edge boiling cooling bed ensures effective cooling of used sand, subsequently elevated through the 2# bucket elevator to the storage silo. The unloader expertly allocates bulk sand to designated bins, each equipped with vibrating disc feeders. Thereafter, the sand is transported to the rotor sand mixer’s storage hopper. Through an advanced screw feeder mechanism, coal powder and bentonite are precisely weighed and blended, guaranteeing uniform mixing in the rotor sand mixer. This refined sand is primed for subsequent molding, assuring superior casting quality.
