Meaning of concrete mixer capacity.

Meaning of concrete mixer capacity.

Meaning of concrete mixer capacity.

Dear sirs,

Meaning of capacity rating of concrete mixer I am intetested in.


RE: Meaning of concrete mixer capacity.

Typically it is the maximum volume of concrete that can be properly mixed in the mixer. I assume this is a stationary mixer not a transit mixer since the capacity is quite large.

You can mix any volume up to and including the maximum stated capacity.

RE: Meaning of concrete mixer capacity.

generally speaking the capacity of a mixer in cu.m. is the quantity (in volume) of aggregates+sand+cement you can load into the mixer. The production of concrete (after compaction) is 70% of loaded volume. For example if you load 10 cu.m. of aggregates, you will produce 7 cu.m. of placed/vibrated concrete

RE: Meaning of concrete mixer capacity.

robyengIT.....that's a bit misleading and confusing. The aggregates occupy about 70 percent of the absolute volume of each cubic meter of concrete. You still have to add the other constituents to create a concrete mix of 1 cubic meter. The capacity of the mixer is the volume of concrete, not the volume of the aggregates alone.

RE: Meaning of concrete mixer capacity.

Yes, what Ron said.

RE: Meaning of concrete mixer capacity.

Looks like this. I can't quite work out how you get the concrete out...

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Meaning of concrete mixer capacity.

Ron : what I wanted to say is that the capacity of the mixer ( at least here in Europe) is the volumetric capacity of the soft mix (not yet mixed). After mixing, the volume is approx 80%. After placing and vibrating, the final volume of concrete is 70% of the initial mix.
i.e. to have a final volume of vibrated concrete in place you need to mix 1.3 x final volume

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
