Introduction Ceramic Foundry Sand, is kind of man-made spherical shape ceramic particles featured by high refractoriness, low thermal expansion made by spraying melted from the fused bauxite. It provides a simple and efficient way in the foundry industry to improving the quality of the castings, reducing the production cost and avoiding environmental pollution so it

Chromite powder use as colorant in glass bottle fields. Originally from South Africa. The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

Ceramic Foundry 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. Chemical and Physical Composition: Main Chemical Composition: Al2O3≥75% Fe2O3≤5% TiO2 ≤5% SiO2:5%-20% Physical
DESCRIPTION: Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa . The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.
