1. The performance mark of the construction concrete; from this, choose what kind of mixing host to use. For water conservancy projects, forced mixing host must be selected. In addition, batching stations and storage bins should be selected according to the types of mixing concrete materials.
2. The task volume and duration of concrete construction; use these two parameters to choose what size mixing station to use. Suppose the total task load of concrete is M; the number of concrete pouring days is T; the number of working hours per day is H; the utilization factor is K, then the specification of the mixing plant should be selected as X=M/(T*H*K), where K is 0.7- 0.9. In the selection, the transportation condition of the finished concrete should also be considered. Such as: direct pumping or vehicle transportation. The volume of the conveying vehicle is also an important basis for determining the model of the mixing station.
