Structural principle of twin-shaft concrete mixer

Twin-shaft concrete mixer is mainly divided into disaster paddle and planetary concrete mixer . The mixer mixing the two stations are a result of horizontal plate . Woe to paddle in the center is equipped with a rotary disc , shaft with several groups blades. Planetary there are two rotary axes , respectively, driven by several mixing spatula. Planetary disk can be divided into fixed and rotary disc . Ang in fixed formula, mixing eradicated around their axis ( rotation ) , the two mounted mixing shaft shovel also co- rotating around the center line of the disc ( revolution ) . In the plate transfer , the two axes do shovel mounted mixing orbital motion , but the entire disk to do the opposite direction of movement.
In the three forms of the concrete mixer , turboprop simple structure , but a larger force shaft , the central disk portion of the volume can not be utilized because there shovel mixing speed is too low. A planetary structure is complicated, but the stirring intensity . In a planetary , the plate transfer more energy consumption , the structure in which the rotation of the stirring plate is not ideal . Fixed disc eliminates the influence of centrifugal force on aggregate , not prone to segregation . Therefore, the plate transfer has been gradually replaced by fixed disc , used portable concrete mixers through a discharge port discharge tray at the bottom , so the discharge quickly , which is one of its advantages . However, if the stirring discharge door seal is not good, it is easy to grout missing from here , so the twin-shaft concrete mixer suitable for mixing the concrete mixing mobility material .
