Ceramsite sand is an artificial spherical casting sand developed by SHXK, same with Japanese Cerabeads. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (at least 30% reduction in binder content), and particles high strength, non-breaking and other excellent characteristics, suitable for all types of sand foundry, especially for the coated sand. There are more successful application cases.
Lehlabathe le feletseng la ceramic le sebelisetsoa ho etsa lehlabathe le koahetsoeng, 'me le sebelisoa khafetsa ka mor'a ho tsosolosoa, le ka ntlafatsang ka katleho boleng le katleho ea tlhahiso ea li-castings, ho fokotsa sekhahla sa li-castings scrape le litšenyehelo tsa tlhahiso ea likhoebo, litšenyehelo tsa nako e telele tsa tšebeliso li tlaase ho feta tseo. ea lehlabathe la silika. Ka hona, lilemong tsa morao tjena, hoo e ka bang limela tsohle tse kholo tsa lehlabathe tse koahetsoeng li sebelisitse lehlabathe la ceramic e le lehlabathe le tala ho hlahisa lehlabathe le koahetsoeng.

● Small than 100kg castings could be achieved without sand coating.
