Improved concrete-mixing process and plant with mixing of components |
(57) Improved concrete-mixing process and relative plant with the mixing of components
in the field of the mixing of cement and non-cement aggregates with the mixing of
components in the dry state thus allowing a fine homogenization of the compound, but
with perfectly dosed single elements.
A process is provided together with a plant subdivided into two areas or basic phases.
The first area or phase consists in dry mixing batches of components, batchwise, the
second area or phase consists in the continuation of the mixing and continuous hydration
of the compound by means of a mixer-feeder.
