Optimal rock fragmentation

Ensuring optimal rock fragmentation when blasting is essential to avoid the additional costs and effort secondary blasting entails.

Get the level of rock fragmentation that you need using our UltrAN products. Choose from our range of Ammonium Nitrates or Calcium Nitrate to achieve blasts that provide optimal fragmentation whatever your geology.

  • Use reliable, easy-to-handle products that offer a high degree of safety with outstanding performance and low cost per energy unit.
  • Improve blasting performance and increase the sensitivity of the emulsion by using Ammonium Nitrate with Porous Prills – such as UltrAN 70 or UltrAN 80.

Avoid secondary blasting

Optimal rock fragmentationUsing Yara UltrAN, you can expect improved rock fragmentation that avoids secondary blasting in the mine. The velocity of the fragmentation is increased by using Yara Technical Nitrates, our tests show.

Using high quality Yara AN-porous prills, designed to ensure a good absorption of fuel oil, enables you to achieve a better oxygen balance. This means you will get a greater energy release and a bigger blast with your civil explosives.

The porosity of the product also ensures its homogeneity down the hole – this results in a very good blasting with a similar size of rock.
