Twin Shaft Concrete Mixer

The Sicoma twin shaft concrete mixer was designed in Italy 20 years ago; it has been refined to give you the outstanding product that you see today. The MAO series heavy duty mixers are the most widely used twin shaft models in the world today; over 6000 in use, worldwide, in ready-mix, precast, block, paver and dam applications.  These mixers produce well over 1 million cubic yards of concrete every day. Their compact size allows them to be retrofitted into existing plants, in most cases doubling throughput without the need for two mixers and splitting of material feeds.

The art in concrete mixing is to make a batch of concrete quickly and completely. The MAO's powerful compulsory spiral mixing action throws particles from each side of the mixer towards the center, where they combine; the water is forced through powerful jets into the mix, where it is absorbed completely, allowing the cement slurry to coat all the aggregate particles uniformly, forming the strongest concrete.
Because the mixing occurs in free space above the mixer floor, the wear on the liner plates is very low; the outer 70% of the lined surface is rarely touched by concrete. Only the rows of tiles close to the discharge door will need replacement and you’ll be surprised at how long they last.
