| All the materials composing the mixture are blended
into suitable mixers equipped with counter-rotating horizontal
axes or with epicyclic vertical blades. The mixture is then distributed
into the moulds, which are subesquently conveyed into the moulding
chamber of the BRETONSTONE SYSTEM machine, constantly kept under
vacuum (740 mmHg). The Vibro-compression Unit transforms the mixture
into a perfectly compacted block. The blocks, once they have been
suitably cured, are cut into slabs down to the required thickness. |
