Volumetric concrete mixer

The Volumetric Concrete Mixer, (also called a Mobile Mixer) was invented in 1964 by Harold Zimmerman, Ephrata, PA USA. By design, all of the ingredients (sand, stone, water, & cement) necessary to produce the concrete desired are stored in separate bins and compartments on the unit, as opposed to being mixed at a central batch plant. Once arriving on the construction site, the ingredients are continuously metered and proportioned through calibrated controls volumetrically into the mixing auger, which in turn homogeneously combines the ingredients to produce concrete. Cleanup is very simple as the mix auger is the only component that needs to be washed out, leaving very little residue.

Volumetric Concrete Mixers are money saving mobile concrete plants delivering any quantity of concrete from one to ten yards - or more - right on the job site. You will eliminate waste and overruns by producing exactly what is needed at the job site, even if the customer over or under estimated the quantity needed. Unmixed materials still on the truck are not wasted - and can be used at the next job - or even the next day. Since a Volumetric Concrete Mixer custom blends fresh concrete on site, you can produce many different concrete mix designs in the same delivery run.
