Secondly, according to the structure of the mixing plant, it can be mainly divided into fixed mixing plants and mobile mixing plants. Fixed mixing plants require foundation laying and have a stable structure. They are usually composed of a mixing main machine, a batching bin, a control room, a cement silo, a screw conveyor, a conveyor belt, etc., and are suitable for long-term and large-scale concrete production. Mobile mixing plants do not require foundation laying, have higher flexibility, and are convenient for moving between different construction sites. They are suitable for temporary or small-scale concrete production.

In addition, according to the mixer mode of the mixing plant, the mixer can also be divided into twin-shaft type and planetary type, which have their own advantages in mixing effect and use characteristics.
