We offer a fully integrated service suite—from equipment manufacturing to seamless installation, precise commissioning, and comprehensive turnkey project solutions. Elevate your operations with our innovative expertise, and witness a transformation in efficiency and productivity.
Green sand production line process: Our meticulously crafted process utilizes clay as a binder to produce exceptional model (core) sand. The mechanization of sand recycling is critical for attaining peak foundry production efficiency. The quality of reclaimed casting sand post-pouring is a major determinant of casting quality, production yield, and cost-effectiveness. This intricate process of recycling and treating used sand involves heavy-duty operations and transportation in challenging conditions, making mechanization indispensable. After pouring and cooling, a vibrating shakeout machine masterfully separates the sand mold, while hot castings are promptly transported to the shot blasting area via a scale conveyor. A strategically placed belt conveyor at the shakeout machine's sand outlet transfers reclaimed sand to the regeneration area. Ingeniously placed cross-placed suspended magnetic separators and belt conveyors remove iron impurities from the reclaimed sand. Dust is meticulously filtered, and the processed sand is stored in small silos. A state-of-the-art boiling cooling bed ensures efficient cooling of used sand, which is then elevated via the 2# bucket elevator to the storage silo. The unloader adeptly 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 ready for subsequent molding, assuring superior casting quality with exceptional precision.
