Compulsory mixer

Compulsory mixer from the early 1950s after the rise, has been rapid development and promotion. First there is the disc vertical shaft forced cement mixing machine. This mixer is divided into two kinds of turboprop and planets. After the 1870s, with the application of lightweight aggregate, there has been a circular groove horizontal shaft compulsory mixer, which in turn sub-single-shaft and twin-shaft two kinds of lying, both self-loading and forced two kinds of mixing characteristics . Its stirring blade speed is small, good wear resistance and low energy consumption, faster development. Forced concrete mixer mixing barrel is equipped with a stirring blade pivot arm, adding mix barrel materials, strong agitation in mixing blades, the formation of cross-logistics. Since the fall of this agitation than the role of a strong agitation, mainly suitable for mixing dry concrete.
Concrete block machine equipped with a spiral mixing blades, respectively mix of various materials by continuous weighing and sent to the mixer, mixing a good concrete continuously outward from the discharge end of the unloading. This mixer mixing time is short, productivity is high, the development of attention.
With concrete materials and construction processes of development, they have appeared many new structural concrete mixer, such as steam heated mixer, supercritical speed mixer, sonic mixer, without stirring blade wobble plate mixers and secondary mixing concrete mixer and so on.
