SF planetary concrete mixers features
SF concrete mixer is a leader in planetary mixer technology; its wide pan and multi-star mixing action gives fast and complete mixing with no dead zones. Large, fully sealing discharge doors and scooped paddles discharge even SCC with ease. Low sidewalls and wide opening covers make access easy and safe.
The planetary (or countercurrent) design has one to three mixing stars (depending on size) 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. The planetary design is the best for drycast concrete and for wetcast and SCC is preferable to the twin shaft design for smaller batch sizes. The reason for this is its intense, compulsory mixing action and complete discharge.
