Concrete Mixing Methods and Concrete Mixers: State of the Art

Apr 01, 2001  2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations of blade configurations and pan.
