 According to its working principle, concrete mixer can be divided into two categories: self-falling concrete mixer and forced mixer.

Self-falling concrete mixer is suitable for mixing plastic concrete.

The mixing effect of the forced mixer is stronger than that of the self-falling mixer, and it is suitable for mixing dry hard concrete and light aggregate concrete.

Concrete mixer is a machine that mixes materials such as sand, stone, cement and water with a certain proportion into uniform concrete that meets the quality requirements. Concrete mixer according to the mixing principle of different it can be divided into self-falling type and forced type two categories.

(1) Self-falling mixer

The inner wall of the mixing barrel of the self-falling mixer is welded with arc blades. When the stirring cylinder rotates around the horizontal axis, the blade continuously lifts the material to a certain height, and then falls freely and blends with each other.

(2) Forced mixer

The forced mixer is mainly based on the shear mechanism of mixing materials. There are blades in the mixer that rotate with the mixer shaft.
