Apparatus for distributing and producing cement mixes, substantially concrete, using an endless conveyor belt movable at the base of separate containers which contain the inert materials and the cement, and a reservoir for the mixing water, to form proportioned mixes in a screw mixer, with unloading of the product simultaneously with mixing; the apparatus comprising a supporting framework, on which are supported, at least one hopper-like prism-shaped container for the inert materials with adjustable discharge openings, and, in a raised position with respect to the hopper for the inert materials, at least one hopper-shaped container with adjustable opening for the cement; an endless conveyor belt being interposed between the framework and the discharge openings of the hoppers for the inert materials and for the cement, which are aligned to each other along an inclined plane; the belt is arranged at an angle along the plane of arrangement of the discharge openings, so as to make contact with, and pass beyond, the cement discharge opening; a screw mixer is associated with the hopper that contains the cement, is arranged so as to have a horizontal axis, and is moved by a suitable drive. The conveyor belt conveys into the screw proportioned amounts of inert materials and cement and then allow their mixing with likewise proportioned amounts of water drawn from the reservoir, simultaneously with the unloading of the concrete from the screw.
