A vibration mechanical method of preparing cement mixtures in which a peripheral flow of concrete affected by vibration sliding deformations, which are generated by torsional vibrations of a concrete mixer body relative to the axis of rotation of a blade shaft with angular frequency ω = 250-335 rad/s and amplitude &bgr; = (0.3... 0.12)/R radians, where R - radius of the inner cylindrical surface of the mixer body, cm. |
