According to the nature of the work concrete mixer can be pided into two types batch and continuous;according to mixing principle concrete mixer can be pided into two types as self loading and forced type;according to installation concrete mixer can be pided into two types fixed and mobile;according to discharge way concrete mixer can be pided into two types tipping and non tipping;according to drum structure concrete mixer can be pided into separating, drum, twin cones, vertical shaft , shaft and etc.types. In addition, the mixer is also pided into mixer crack Drum and circular trough (horizontal axis). Function of concrete mixer: 1.Make each components of macro and micro evenly. 2.Destruction of cement particle agglomeration, and promote the development of the diffusion phenomena. 3.Initial destruction of the surface of the cement particles hydrate film wrapped layer. 4.Make the material inter-particle colpsion friction, reduce the impact of dust film. 5.Increase the number of mixing materials unit body to participate in sports and trajectory crossover frequency, acceleration homogenized.
