Detailed Product Description
The Sicoma high speed planetary / countercurrent concrete mixer is a leader in its class; its design has been refined over many years, from an uncompromising basic design that satisfies the perfectionist to the little touches that you expect from a truly World Class European product. Over 8000 in use.
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, 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 you 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 like nothing else can.
Unlike others of similar design, the paddles and gears are arranged so that 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. The consequence is that the mixing action is perfect and the blades do not have to be oversized to do it. Additionally, discharge is fast and complete without the need for a wide scraper tail which creates dead spots in the mixer.
