Ceramsite is a spherically shaped bauxite sand manufactured by melting bauxite in an Electric Arc Furnace followed by a proprietary spraying process. SuperSand beaded foundry sand provides a unique combination of spherical shape grain, chemistry, and physical properties that result in numerous performance advantages compared with other foundry sands. Our SuperSand (Ceramsite) performs very well

Ceramic Foundry sand ,also called as Fused Ceramic Sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.At the present, Ceramsite is acknowledged in the

After sand has been shaken off a complete casting, the lumps are cooled and crushed. All particles and metal granules are removed, often with the assistance of a magnetic field. All sand and constituents are screened with shakers, rotary screens, or vibrating screens. Cleaned sand can then be reintroduced to the beginning of the molding

Ceramic sand, technically as fused ceramic sand for foundry, is made from calcined bauxite which main content is aluminum oxide, processed by melting, blowing, sieving and blending. Ceramic sand has excellent properties, including spherical shape, high refractoriness, good crush resistance, inert chemical characteristics, high reclamation yields, etc. To solve the problem of metal penetration and

Sand casting, known as sand molding casting, is a casting process that uses sand as a mold. Then pour the liquid metal into this mold to create a casting part.It is one of the oldest casting processes. It can be used to make metal components of all sizes, ranging from 1kg to hundred tons. The
