Then a succession of sieving and grinding with roller crushers was applied to deagglomerate the sediment. Toothed and fluted roller crushers were used. 13.5 tons of material were recovered and it consists of sufficiently fine particles to be incorporated in concrete and especially enter in the mixer of the concrete plant.
