Ceramic Foundry Sand Production Process
Strictly adhere to the standards of each production process, and provide high quality and reliable casting materials for domestic and foreign enterprises.
To produce Ceramic Foundry Sand, operators need to put the calcined bauxite containing 65%-85% aluminum oxide into the electric arc melting device. The ore melts into liquid outfow under high temperature. At the moment, the outflow is blown into fine particles by the compressed air with a certain pressure. By the surface tension, the spherical or spheroidal sand grains are made with smooth surface. After cooling and sieving, the ceramic foundry sands of different particle are graded. At last, the final products of ceramic foundry sand packed to meet the different customers’ requirements
