Abstract (en)

[origin: WO2016071197A1] The invention relates to a method for producing gravels from rocks, which gravels are used as finished products and are separated into fractions of different grain sizes. Said method is characterized in that the rocks are first pre-crushed, then at least partially crushed further by means of high-pressure roller grinding, and then classified. A system suitable for performing said method comprises a crushing device (2), a high-pressure roller grinding device (3) arranged downstream of the crushing device (2), a classifying device (5) arranged downstream of the high-pressure roller grinding device (3), and storage places (6, 7, 8) arranged downstream of the classifying device (5) for separately storing the fractions of the gravels.
