1. Twin-shaft mixer
The agitating process of the twin-shaft mixer occurs not only in the radial direction but also in the axial direction. The main mixing zone is located in the circumferential direction of the agitating body, and the energy value in this direction is maximized during the entire agitation process, so that the agitation space can be fully utilized, so that the aggregate speed of the aggregate, cement and water in the agitating blade is low (1.4 to 1.6). In the case of m/s), the most uniform optimum agitation mode is achieved in the shortest time to achieve the best mixing effect.
2. Single horizontal shaft mixer
The mixing principle of the single-shaft mixer and the self-dropping mixer is basically similar. The rotation of the stirring shaft (blade) is to raise the concrete to a certain height, and then let it fall freely to complete a stirring process. Therefore, when the single-shaft mixer is used, the effective working volume is smaller than the theoretical design volume, and the overall height is much larger than that of the twin-shaft mixer. In the production of RCC, the actual production efficiency of the single-shaft mixer is lower than the rated production efficiency.
