Product Description
Clay sand, celebrated for its superior binding attributes, is indispensable in molding operations, utilizing clay as its primary binder. Within the foundry ecosystem, the sand treatment division is pivotal, ensuring the molding core-making department is equipped with premium-quality molding sand. The careful preparation of this sand is a decisive factor, directly impacting the high standards of casting production, enhancing output rates, and minimizing production expenses. Due to the complex procedures involved in sand treatment, the labor-intensive tasks of clay sand processing and transportation are both extensive and challenging. Therefore, the mechanization of the sand treatment process remains a fundamental element of casting production, guaranteeing seamless efficiency and unwavering reliability.
Qingdao Sanzhuji Technology Co., Ltd. stands out as a beacon in the field of clay sand treatment line design and execution, providing a full spectrum of services that include equipment manufacturing, installation, commissioning, and delivering complete turnkey projects.
Innovative Green Sand Production Line Process: Our expertly crafted procedure employs clay as a binder in creating modeling (core) sand. Mechanizing the sand recycling operation is essential for optimal foundry productivity. The quality of casting sand reclaimed after pouring significantly influences the overall casting excellence, production rates, and cost-efficiency. The intricate recycling and treatment of used sand demand extensive processing and transport under tough environmental conditions. Mechanization in this phase is indispensable. After pouring and cooling, our advanced vibrating shakeout machine (drum shakeout machine) effectively dislodges the sand mold, while hot castings are smoothly transferred to the shot blasting area using a precision scale conveyor. A tactically positioned belt conveyor at the shakeout machine's sand outlet conveys recovered sand to the regeneration zone. Cross-placed suspended magnetic separators and belt conveyors skillfully eliminate iron impurities from the recycled sand. Dust is meticulously filtered out, and the processed sand is stored into compact silos. A cutting-edge boiling cooling bed ensures efficient cooling of the used sand, which is then elevated via the 2# bucket elevator to the storage silo. The unloader expertly allocates bulk sand to dedicated bins, each equipped with vibrating disc feeders. Subsequently, the sand is transported to the rotor sand mixer’s storage hopper. Through a state-of-the-art screw feeder system, coal powder and bentonite are precisely weighed and seamlessly blended, ensuring uniform mixing in the rotor sand mixer. This meticulously refined sand is then primed for subsequent molding, guaranteeing unparalleled casting quality.
