Concrete mixer is the cement, sand and gravel aggregate and water are mixed and mixed into the concrete mix machinery. Mainly by the mixing tube, feeding and unloading mechanism, water supply systems, the prime mover, transmission, chassis and supporting devices and other components.

Divided by the intermittent nature of the work (batch) and continuous; divided by mixing principle and compulsory self-loading; divided by installation of fixed and mobile; tipping points by way of the material and non tipping type; press the mix in the form of cylindrical structure divided pear type, drum drum, double cone, disc vertical shaft and horizontal axis circular groove and so on.

Blender maintenance: Maintenance of the body clean, remove dirt and obstacles on the body; checking oil and lubrication circuits and control equipment at the press requires filling oil; work before class, add water while stirring cylinder idling 1-- to 2min, while checking the clutch and brake work reliability; concrete mixer during operation, inspection should always listen to the motor reducer, transmission gear noise is normal, the temperature rise is too high; end of class work , it should be carefully cleaned concrete mixer.

With the development of concrete materials and construction processes, and have appeared in many of the new structure of concrete mixers, such as steam heating mixer, supercritical speed mixer, sonic mixer, without stirring blade wobble plate mixer and secondary mixing concrete mixer and concrete mixer parts.
