Explo Anfo is a general-purpose explosive produced by mixing porous ammonium nitrate with diesel oil. The even distribution of the oil in the ammonium nitrate is achieved with the help of spray nozzles (injectors).
EXPLO ANFO
It is not water resistant and its use is recommended only in dry holes. The product is used at temperatures from -20oC to 40oC.

Features
Usage
- In surface applications (quarries, mining, road construction trenches, public works, etc.) in holes with a diameter greater than 65mm with the help of booster (Explo Gel 100).
- In horizontal underground blast holes larger than 40mm, with compressed air supply (recommended pressure is 3.5 – 4.0 bar) and with the help of a strong booster (booster) Explo Gel 200. In this case measures should be taken to avoid static electricity.
- It is activated with the help of a booster placed at the base of the hole, using a detonator (non-electric, electric) and detonating cord.
Advantages
It provides optimal charging in vertical boreholes due to its free flow, achieving a very good charge density (Φ of hole = Φ of explosive column), resulting in the production of a large volume of aggregates with very good crushing.
It is a low-cost, simple-to-apply explosive.
Self Life
Storage - Handling
Must be stored in temperature range between -0 °C and 30 °C. Explo Anfo should be stored in explosives magazines class 1.1D, according to legislation. It should be handled and transported according to its Safety Data Sheet (MSDS).
