Introduction of planetary concrete mixer

2017-04-24

Since the beginning of the 20th century, the drum-driven concrete mixing plant driven by the steam engine has begun to emerge. After the 1950s, reversing the discharge and dumping of the material of the double cone mixer and cracker mixer, etc. have come out and developed. There is a radially arranged stirring blade on the inner wall of the mixing cylinder of the fall concrete mixing plant. Work, the mixing cylinder around its horizontal axis of rotation, adding the material within the mixing tank, the blade raised to a certain height, by the weight drop, so that the cycle of movement, to achieve the effect of uniform mixing. Since the concrete structure of the concrete mixing plant is simple, generally to focus on plastic mixing concrete.

Forced mixer from the early 20th century, the rise of the early 50s, has been rapid development and promotion. The first is the emergence of a disk vertical axis forced concrete mixing plant. This mixer is divided into two types of turbo and planetary concrete mixer. After the 19th century, 70 years, with the application of light aggregate, there has been a circular groove horizontal shaft forced mixer, it is divided into single horizontal and double horizontal axis of two, both from the fall and forced two kinds of mixing characteristics The The speed of the stirring blades is small, the wear resistance is good and the energy consumption is small, the development is faster. Mandatory concrete mixing plant Mixing cylinder inside the shaft with a stirring blade on the shaft, adding the material within the mixing cylinder, stirring in the mixing of the blade to form a cross-flow. This stirring method is far stronger than the self-falling stirring method, mainly suitable for stirring dry hard concrete.

The continuous concrete mixing plant is equipped with helical stirring blades. The materials are fed into the mixer according to the batch ratio. The mixed concrete is discharged from the discharge end continuously. This stirrer has a short mixing time, high productivity, and its development is compelling.

With the development of concrete materials and construction technology, there have been many new structure of the concrete mixing plant, such as steam heating mixer, supercritical speed mixer, acoustic mixer, no stirring blade swing disc mixer and the second mixing of concrete mixing plant Wait.
