Chromite Foundry Sand

Foundry Grade chromite sand, also known as chromite ore, is a special sand for foundry. It is a natural spinel dominate by chromite. After crushing, grinding sieving and batching to typical Particle size distributions as per customers’ requirement, it is suitable for moulding in foundry. Our standard material is a 4-sieve distribution. This means that 4 sieves contain more than 10% retained. Our current material has more than 90% on the ASTM 40-100 sieves. A typical sieve distribution is shown below.
