A method for preparation of cement-concrete mixture includes forced mixing mineral components, cement and make-up water with simultaneous displacement of the formable mixture both over the periphery of cylindrical housing toward the side of unloading and on the center toward opposite side. The peripheral flow is formed in the form of a ring with external radius, which is equal to the radius of internal surface of the mixer housing, and internal radius and it is turned relative to the rotational axis. The central flow is formed in the form of a continuous round cylinder and it is turned relative to the rotational axis. |
