Chemtech Engineers supplies a full range of high-energy bulk explosives for every mining application. The bulk explosive trucks are capable of delivering any formulation from pure emulsion explosives, doped emulsion. These trucks are able to supply you with a custom explosive blend that has the energy characteristics and performance you need. Our multiple mix units have the ability to manufacture ANFO and Heavy ANFO to auger or pump a blended product into blast holes. Bins are generally permanently fixed to the chassis. These units consist of an ammonium nitrate storage bin , emulsion storage tank, fuel oil tank, water tank, hose reel and optional product additions tanks.
The product is discharged using a side-mounted discharge auger, or pumped into a wet blast hole using a loading hose. Emulsion is generally added to the ANFO in the discharge auger. A helical rotor pump is used to transfer the product during the wet hole loading process.
Hose reels can be manufactured to suit the various discharge rates and hose diameters as required. These reels are usually driven using a reduction gearbox. These reels are driven using a reduction gearbox to give optimum control of the hose feed rate in the hole.To achieve a waterproof product, at least 50% emulsion will need to be added. However, to obtain a product that can be reliably pumped, you will need to use waterproof heavy ANFO with between 60-70% emulsion. Heavy ANFO is pumped through a hose, with the hose retracting as loading proceed
