What is the turbidity of foundry grade chromite sand?
Turbidity (NTU)
Currently, foundry-grade chromite ore primarily from South Africa, either raw bag sand or 44-grade raw material, and is further processed domestically.
The turbidity of foundry-grade chromite ore directly impacts product performance, especially when used as a chromium drainage sand.
Under normal circumstances, the turbidity of chromite ore is controlled within 200 NTU.
The main factors affecting turbidity are:
1. The purity and cleanliness of the raw material are inversely correlated; the higher the purity, the lower the turbidity.
2. The water washing process during the production process can effectively improve the turbidity of the product.
3. Dust control during the screening process also has a certain impact on the turbidity of the product.
