Granulometric properties

Our plant is fully automated. The gradation of the dolomite can be adjusted very fast based on our customer needs. Complete size analysis are taken and compiled constantly to make sure we respect our customer specifications for the final product.

The Dolomite Fines we produce are characterized by their very fine size and high content of Magnesium. These fines can be used in numerous products, mainly for agricultural purposes. This product helps to balance the soil PH and the very fine size makes the spreading and penetration into the soil fast.
