Why is the twin shaft concrete mixer so good?

Concrete mixer has many kinds, but the machine commonly used as a host is JS concrete mixer, which is related to JS concrete mixer good mixing effect, so why double shaft concrete mixer mixing effect so good?

Twin shaft paddle mixer mixing device consists of two horizontal axis and installed on the shaft of the stirring arm and blade, blade directions on the two axis are different also, so that it can guarantee the mixture in the cylinder inner loop movement.

When twin shaft mixer in operation, in theory, the end of blade cuts the concrete from the top to the tank, the other end with a blade grabbed from the concrete, in the process of two groups of blade alternates work, discharge blade mixes up under the side at the bottom to form no or less material space, at the same time cutting blade to mix from one end to the other side of the axial and circumferential displacement of the composite, and the other shaft on the blade mix the concrete in the opposite direction, which makes concrete circular movement within the cylinder.

Also piqued concrete is at the back of the blade, which produces the continuous friction between the mix. Due to the different linear velocities at the cutting end of the blade, the mixing materials have a large relative displacement when they are compressed, so the larger cement aggregates will be dispersed and refined.
