Twin spiral shaft concrete mixer:
With no-shaft structure, brings less energy consumption and more efficient.

1. Twin spiral shaft mixer with double radial flow, double axial flow and double shearing, so the mixing more smoothly.
2. Twin spiral shaft mixer without two horizontal shafts and arm in the center of mixer, so the inner space is bigger.
3. There is no shawft and arm in the twin spiral shaft mixer, so there is no agglomeration of concrete on the arm.
