Bulk ExpanfoTM

For anfo and heavy anfo systems

function

Expanfo™ is an innovative in situ ANFO (Ammonium Nitrate Fuel Oil) product where, in addition to natural porosity, sensitising plastic microspheres are included insitu in each ammonium nitrate prill, which is mixed with fuel oil in Mobile Manufacturing Units (MMUs). Bulk Expanfo™ is used in dry opencast, quarrying and construction applications.

Note: The microspheres remain intact during pneumatic loading, thereby allowing Expanfo™ to retain a lower density and increased sensitivity in the blast hole. This will result in a more ideal detonation behaviour and superior fi eld performance compared to that achieved with equal volumes of standard market ANFO products.

description

Bulk Expanfo™ gives superior control and generally more consistent and predictable blast results, especially in tough but dry blasting con-ditions. Bulk Expanfo™ is manufactured in three grades varying in product strength and detonation characteristics to provide the customer with a product that represents the highest value solution for the specific application.

advantagessafe Expanfo™, due to its low sensitivity to shock, friction or impact, is comparatively safe to handle and use. Treating or washing the charge hole with water, will render the Expanfo™ insensitive.

reliable Anti-caking agents make Expanfo™ free-flowing for improved performance in underground or surface applications. Expanfo™ will reliably initiate with any 6D detonator when loaded pneumatically. Due to microspheres, Expanfo™ exhibits improved sensitivity characteristics.

quality Manufacturing of this product conforms to the ISO9002 quality standard. Tests are conducted on the PPAN to confirm that the density, particle size, moisture content and flow properties conform to specifications.

flexible Easy to charge pneumatically, or by using an auger.

cost effective Full coupling and Expan™ technology ensures maximum energy levels are achieved for best results.

product information

expanfo™ 100Expanfo™ 100 is a low density ANFO product for easy / non-demanding conditions or any application where low energy is required.

expanfo™ 200A medium density of Expanfo™ 200, (when compared to standard ANFO) is a general purpose ANFO product for hard rock applications where over-break or excessive fines have to be limited.

expanfo™ 300Expanfo™ 300 is a high density ANFO product for tough conditions or any application where higher energy is required.

ANFO products (RWS = 1). However, actual detonation performance of ANFOproducts deviates significantly from this ideal. Expanfo™ products detonate closer to

the ideal due to the inclusion of the sensitising microballoons. The in-hole density decreases from Expanfo™300 to Expanfo™100.

important instructions

• Always store detonators and explosives separately.

• Keep ANFO away from sparks, flames or any other source of ignition.

• Store explosives according to the country rules & regulations.

• ANFO is soluble in water and can therefore not be used in wet conditions.
