Concrete Mixing Plant The main equipment adopting twin forced horizontal shafts stirrer can be used to produce dry and stiff or plastic concrete. The aggregate is measured alone or accumulated by the electronic scale cement, water and the additive are measured accurately under the centralized control of the computer. It is easy to operate and debug. There are two models for feeding aggregate. Electric elements select the device of Siemens for use which is reliable and high in efficiency. The machine is suitable for the concrete production in enormous quantities of scene .
