Abstract

Apparatus for the production of concrete, able to be installed advantageously in a building site and comprising a hopper (13) in which cement and inert materials are able to be loaded, and a mixer (20) with a horizontal axis, in turn comprising a mixing drum (21) inside which rotary mixing blades (22, 23) are present. The mixing drum (21) is provided with a loading aperture (30) and a discharge mouth (31). The mixing drum (21) is movable, by means of rotation with respect to its horizontal axis, between a loading position, in which both the loading aperture (30) and the discharge mouth (31) are disposed substantially above a horizontal plane passing through the horizontal axis, and a discharge position in which only the loading aperture remains above the horizontal plane.
