摘要： An apparatus for making concrete is disclosed. The apparatus includes one or more measurement devices that is used to provide controlled quantities of at least cement and sand; a high intensity mixer that receives the controlled quantities of the cement and sand, mixes the controlled quantities of the cement and sand to produce grout, and outputs a flow of grout; and a controller coupled to the measurement devices and the mixer. The controller monitors and controls mixing energy applied by the mixer during mixing. In one embodiment, the mixing energy is altered by controlling the degree of opening of a discharge gate of the mixer. A concrete plant design including such an apparatus is also disclosed.
