I have a query for those familiar with construction machinery. Recently AMW has launched truck mounted concrete batching plant. MAN India also has listed a rigid multi axle truck mounted concrete batching plant in its construction range. Besides trailer mounted mobile batching plants have been available from many companies. A while back, I came to know about Volumetric concrete mixers which are gaining popularity in developed nations. Compared to transit concrete mixers, which have to continously run the mixing process, volumetric mixers mix concrete from stored materials either on move or stationary at site. This approach is considered economical and less wasteful. Material can also be directly fed into volumetric mixer bins at site. I searched for volumetric mixer in India, but found almost no results. But there are plenty of compact mobile batching plants. Construction experts please confirm that volumetric mixers and mobile batching plants launched by AMW and MAN are same thing.

I know that this is not a construction forum, but out of curiosity I am asking as construction vehicles are subset of CV space now-standing EXCON held.

Question: A drum mixer would be able to output 5 m^3 of concrete almost instantly, since it's pre-mixed. What about a volumetric mixer? Would it take some additional time to output & mix that amount of concrete? How much mixing is required before the concrete is usable?

Time is not a problem as in both the cases the concrete has to be pre-ordered. One can schedule the delivery based on the requirement and that is not a big deal for construction industry. The Engineers can plan the mixin time and quantity well in advanve based on the grade of concrete required.

Yes they are pretty much the same thing. The main advantage of these units over drum mixers is that you can mix concrete as per your need, where as in drum mixers you have to consume the entire concrete or waste the left over. Another advantage is that volumetric mixers are not time dependent as the ingredients are stored separately where as drum mixers have to be poured out within 3 - 4 hours or the concrete begins to set inside the drum itself. Batching plants are available ranging between 8 - 60Cu.M/hour where as drum mixers can only handle 6 - 8 Cu.M.
