<p>Device for the artificial ageing of stones with at least an ageing channel (3) arranged on a support (1), a vibration device (5) to set the support (1) in motion, and a conveying device (8) t o move the stone (2) through the ageing channel (3). The ageing channel (3) has at least a first and a second impacting surface (6, 7), which apply the ageing effect to the stone (2). The ageing channel (3) comprises at least two sections, wherein the stone (2) moves through a first section (301) in a first feed direction and wherein a second section (302) runs at an angle to the first section (301), so the stone (2) is deflected in its feed direction to move into a second feed direction.</p> |
