Product Description
Clay sand, revered for its superior binding properties, is an essential element in molding processes where clay acts as a binder. The sand treatment division is a vital component within the foundry, responsible for delivering top-tier molding sand to the core-making department. The careful preparation of this molding sand plays a pivotal role in the production of excellent castings, enhancing output while significantly reducing costs. Due to the complex nature of sand treatment processes, the demands of clay sand treatment and its transportation are substantial, navigating challenging conditions. Hence, the mechanization of the sand treatment process is a fundamental aspect of casting production, ensuring both efficiency and remarkable reliability.
Qingdao Sanzhuji Technology Co., Ltd. is a distinguished leader in the design and implementation of clay sand treatment lines. We offer all-encompassing services that include equipment manufacturing, installation, commissioning, and the execution of complete turnkey projects, delivering unparalleled expertise and results.
Green Sand Production Line Process: Our meticulously crafted process employs clay as a binder to create modeling (core) sand. The mechanization of sand recycling is integral to the efficiency of foundry production. The quality of the recovered casting sand post-pouring has a significant impact on the overall quality, production yield, and cost-saving efficiency of castings. The intricate procedures of recycling and treating used sand involve intensive processing and transportation in challenging environmental scenarios. Mechanization in this segment is indispensable. Post-pouring and cooling, a vibrating shakeout machine (or drum shakeout machine) adeptly separates the sand mold, while hot castings are smoothly transitioned to the shot blasting area via a scale conveyor. A strategically aligned belt conveyor at the shakeout machine's sand outlet carries the reclaimed sand to the regeneration area. Cross-positioned suspended magnetic separators and belt conveyors efficiently extract iron impurities from the reclaimed sand. Dust is meticulously filtered out, and the processed sand is stored in compact silos. A cutting-edge boiling cooling bed ensures the efficient cooling of used sand, which is then elevated by the 2# bucket elevator to the storage silo. The unloader skillfully allocates bulk sand to designated bins, each equipped with vibrating disc feeders. Consequently, the sand is transported to the rotor sand mixer’s storage hopper. Through an advanced screw feeder mechanism, coal powder and bentonite are precisely measured and blended, ensuring even mixing in the rotor sand mixer. This refined sand is then primed for subsequent molding, guaranteeing superior casting quality.
