Product Description
molding sand ceramic sand for foundry is an advanced substitutes of quartz sand in casting field. Ceramic sand is made from calcined bauxite with main content of aluminum oxide processed by melting, blowing,sieving and blending. After melting calcined bauxite with 65-90% aluminum oxide in high temperature electric arc melting device, the outflow of ceramic blown into fine particles. Then after cooling and sieving,the ceramic sand become finished particles with different size grade.
Features：
1.Perfect round ball shape
Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin use level
Smooth surface of spherical shape greatly improves collapsibility after pouring
Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin use level
Smooth surface of spherical shape greatly improves collapsibility after pouring
It easy to shake out after foundry process due to it's spherical shape.
2.High refractoriness
Superior refractory equivalent to zircon and Chromites
Higher than silicon sand, can be used for casting various materials.
Non-stick, non-sintering on the casting, which reduces the deformation of the casting.
3.Low coefficient of thermal expansion
Can be comparable to the zircon sand.
Ensures fewer or no casting defects such as veining and deformation.

3.Low coefficient of thermal expansion
Can be comparable to the zircon sand.
Ensures fewer or no casting defects such as veining and deformation.
4.Low gas evolution and high permeability
Can reduce defects, increase overall yield of casting and lower the cost of casting materials.
5.Low bulk density
The bulk density is 1.79-1.87/cm3, lower than the chromite sand of 2.5-2.9/cm3.The sand core is easy to move with light weight, and also can reduce the usage amount of sand.

6.Save resin consumption with casting tech such as shell molding,Resin coated sand casting,Vacuum casting,etc.
7.Recycle up to 10 times,highly cost effective.
For it's recyclable feature, the ceramsite sand is enviroment-friend material for foundy.
For it's recyclable feature, the ceramsite sand is enviroment-friend material for foundy.
8. High strength
Good compressive strength and bending resistance ability and low broke rate.
