RAW MATERIALS
雅固岗石的候选原石,在平均米径、色泽、密度及含水率上,必须是上之选, 才能符合雅固岗石的品质标准。
精挑细选的标准原石,依其花纹、颜色、大小分门别类,再依不同的制作配方,用碎石机細碎成各种粒径的碎石。
The stone materials - aggregates and fillers -used for the manufacture of AGROSTONE blocks, are divided according to a grading scale previously selected and then stored into suitable silos. According to the AGROSTONE typology desired, the aggregates and fillers are taken out from the silos, already divided into the various granulometries and quantities.
A suitable weighing/batching mechanism connects the silos with the mixing and mixture preparation units. The stone materials can be bought from the various producers, already screened in the suitable grading scale, or they can be bought in more or less big sizes and then crushed and selected using one's own plant.
