According to the nature of the work, it can be divided into intermittent (batch) and continuous types; According to the mixing principle, it can be divided into self falling and forced types; According to the installation method, it can be divided into fixed and mobile types; Divided into tipping type and non tipping type according to the discharge method; According to the structure of the mixing drum, it can be divided into pear type, drum type, double cone, disc vertical shaft type, and circular groove horizontal shaft type. Therefore, specific operations should be carried out according to the classification.

1. Classified by job nature:

(1) Periodic working mixer; 

(2) Continuous working mixer.

2. According to the mixing principle:

(1) Self falling mixer;

(2) Forced mixer.

3. According to the shape of the mixing bucket:

(1) Drum type;

(2) Cone shaped;

(3) Disc style.

In addition, mixers are also divided into split tube and circular groove (i.e. horizontal shaft) mixers.
