Planetary Mixer

The planetary (or countercurrent) design has from one to two mixing stars that rotate themselves while also rotating around a central point, allowing each arm to cover the whole mixer floor in a number of revolutions. This powerful mixing action is both fast and thorough, resulting in a mixing time, after water is added, of 30 seconds or less for most types of concrete. The result is greater throughput, giving more concrete per hour for the same size plant, as well as better consistency and greater strength or, on the other hand, a saving on cement.
