The NUVM 1.5 volumetric trailer mixer from Britain’s Nurock Mixers mixes nearly 2 cubic yards of concrete in under three minutes using a unique combination of hoppers and hydraulics. It can produce screed, mortar or process recycled aggregates with a constant production rate at any cement content. Replacing chains, sprockets and other mechanical actuators with a hydraulic system speeds production and reduces the number of moving parts. The compact mixer combines compartments for sand, stone and cement in one hopper and stores water under it, reducing the overall footprint by about 25 percent. An optional on-board computer holds up to 50 preset mix designs.
