OREANDA-NEWS. June 18, 2013. “AutoKrAZ” in partnership with Zvezda Machine Building Plant (Karpinsk, Russian Federation), leading manufacturer of mix pump trucks and rotary drilling rigs, has built a new mix pump truck МЗ-3Б-16 based on the KrAZ С20.R dump truck. Capacity of the mix pump truck is 600 kg/min.

The С20.R truck (6х4) is provided with 6-cylinder YaMZ-6511 engine (Euro 4), rated at 362 hp, produced by Yaroslavl Engine Factory under Renault license, the MFZ 430 single disk clutch. This truck also features a comfortable Renault Kerax cab, 3 tons Palfinger crane.

The KrAZ С20.R (МЗ-3Б-16) mix pump truck is used for carrying explosives or their components and loading holes with a diameter of 130 mm and over with all kinds of factory-produced granular explosives allowed for mechanical loading as well as with igdanit (ANFO) and granulite "E" prepared on-site by mixing.

Granulite "E" is a mechanical mixture of ammonium nitrate and ammonium nitrate emulsion. The mix pump truck is provided with two independently driven and controlled systems: system for diesel fuel supply for preparation of ANFO and emulsion supply system. For better filling of emulsion supply pump the truck is provided with boosting system powered by truck pneumatic system to build up air pressure up to 0,05 MPа (0,5kgf/cm2) in emulsion tanks.

Preparation of granulite "E" during loading process considerably extends the range of truck applications and reduces cost of blasting.
