1. Choose according to the requirements of the engineering quantity and construction period: When the concrete engineering quantity is large and the construction period is long, medium or large fixed Medium concrete mixer or mixing station should be selected. If the concrete volume is small and the construction period is short, small and medium-sized mobile mixers should be used.
2. Choose according to the type of concrete designed: when Medium concrete mixer is plastic or semi-plastic, a self-falling mixer should be used. If the mixing concrete is high-strength, dry hard or lightweight concrete, a forced mixer should be used.
3. Choose according to the composition characteristics and consistency of concrete: If the consistency of Medium concrete mixer is small and the aggregate particle size is large, a self-falling mixer with larger capacity should be selected. For example, when mixing concrete with large consistency and large aggregate size, a self-falling mixer with a faster mixing drum speed should be used. If the consistency is large and the aggregate particle size is small, it is advisable to use a forced mixer or a mixer with a medium and small capacity conical reversal discharge.
