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. Physical and Chemical Properties: Item Unit Index Cr2O3 % 46.0min SiO2
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

Nice Foundry Sand (NFS CERAMSITE) is a kind of a new artificial Foundry sand that is ball-shaped, high heat-resistant, low heat dilating rate. NFS has advantage of cost and performance than Chromite sand and zircon sand that provide the effective ways to increase improve the quality of the foundry, cost-down and less damage to the
