What is the effect of concrete mixer in low efficiency area

The falling point of aggregate powder in the concrete mixer is required to be in the center of the concrete mixer and avoid the two mixing shafts. Today, let's briefly understand the phenomenon and effect of the low efficiency area of the mixer in the work?

In the low efficiency zone, the mixture moves slowly, and the convection and infiltration between phases are not intense, which is easy to make the mixture adhere to the mixing shaft and form a "shaft holding" phenomenon. Vibration mixing method, working device optimization method and double row mixing blade structure can effectively eliminate the low efficiency zone of mixing. Eliminate the inefficient mixing area, and the linear speed of the mixing arm at one end close to the mixing shaft is too low. In order to prevent concrete segregation, the linear speed of mixing blade shall be limited to the maximum value at the outer end of mixing arm. In this way, at the end close to the mixing shaft, due to the relatively low linear speed, the mixing low efficiency zone or even dead zone is formed.
