Planetary Mixer

The Sicoma high speed planetary / countercurrent concrete mixer the best in its class. From its beginnings as an uncompromising basic design it has been continuously refined over many years, so that today’s product  contains the little touches that you expect.  There are more than 8000 Sicoma  high speed planetary / countercurrent concrete mixers in use today around the world.

The planetary (or countercurrent) design has one or 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, results in a mixing time, after water is added, of 30 seconds or less for most types of concrete. The result is greater throughput, providing 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. Sicoma’s planetary design is superior to turbine and twin-shaft designs for production of all types of dry-cast concrete. The reason for this is its intense mixing action, which breaks up zero-slump mix quickly.

Unlike others of similar design, the paddles and gears are arranged so every inch of the mixer floor is swept with high repeatability over 60 seconds of operation., each arm sweeping an inch or so behind its previous path and alternate arms covering the gaps so that, even with blades removed from the arms, every particle of concrete would be moved.
