Application of Ceramsite Sand:
- Widely used in foundry techniques like resin-bonded sand, sodium silicate sand, and clay-bonded sand for sand core and casting mould making.
- Replace chromite sand and widely used in the sand core making like jacket core, oil duct core, and engine’s tappet core.
- Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).
- Widely used as dry sand and sand box for EPC process and V method of casting processes.
- Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
- Widely used as cleaning sand for copper and aluminum alloy castings.
Advantage of Ceramsite Sand:
- Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin leve
- The smooth surface of the spherical shape greatly improves collapsibility after pouring.
- Very low thermal expansion ensures fewer or no casting defects such as veining and deformation.
- Excellent thermal conductivity and heat absorption capacity close to that of Zircon
- Superior refractory equivalent to Zircon and Chromites
