This machine is the latest crushing technology worldwide and was the first of its type in New Zealand. The plant is accompanied by a 24tn wheel loader and a 30tn excavator. These three machines work in unison to produce road base material from AP65 down to AP20 and, depending on the quality of the raw feed, M4 products can also be produced. This machine works very well in hard rock quarries such as the numerous basalt and greywacke sites found throughout Otago as well as alluvial deposits.
