How does a concrete batch plant work | Operation of

Needless to say, the discharge time of this concrete mixer is slow. So, non-tilting concrete mixer has its use for smaller projects only. Moreover, this type of concrete mixer is more suitable for mixing smaller size aggregates, because the larger sizes segregate easily. It's mixing capability is also not that much efficient.

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.
