The period of emergence of the concrete mixer appeared in the mixing form of gravity type. With the increasing requirements of concrete, the forced mixer appeared. Forced mixer can be divided into vertical and horizontal shaft. There are almost these two forms of mixer in domestic.

The vertical mixer can be traced back to the early twentieth century. The drum type concrete mixer driven by a steam engine has appeared in the beginning of the20 century. In the next fifty years, the double cone mixer of reversing the material type and pouring over discharging material type. In addition, the split drum mixer comes out in succession and gets development. The gravity type concrete mixer gets the considerable development. After the rise at the beginning of the 50's in the twentieth century, the forced mixer has got rapid development and promotion. The first is the disk spindle type forced concrete mixer. The mixer consists of eddy paddle and planetary type. After the 70s, with the application of lightweight aggregate, the circular groove horizontal shaft type forced mixer, also called horizontal shaft mixer appeared. It is divided into a single horizontal shaft type and double horizontal shaft type, there are two mixing characteristics of gravity and forced.

China has successfully developed at the beginning of the 80's in twentieth century, and due to the rapid development concrete batching plant without mixer, the specifications and the number of products are far more than other models. The stirring mechanism is the core parts of the twin shaft mixer. Concrete mixing quality Ready Mix Concrete Plants, productivity, use and repair costs are associated with it. The stirring mechanism consists of a stirring shaft the installation and the stirring blade by double circular groove arranged in the horizontal cylinder shape with two rotating in opposite directions.
