Abstract

An artificial stone having a chiselled, rough-hewn look on the edges, corners and exposed faces of the product, is produced by preparing a concrete block and then fracturing it, preferably along one plane, to produce a somewhat rough face along the fracture. The fractured block is then placed into the upper end of an inclined rotating cylindrical tunnel, the tunnel having at least one and preferably two internal longitudinal ribs to initially lift the block and then produce tumbling as the tunnel rotates, the block gradually moving along the tunnel towards a lower exit end. The multiple impacts and abrasions within the tunnel produce the desired degree of additional texturing and rounding of corners and edges, to provide the desired natural aesthetic appearance.
Preferably, one or both of the angle of the tunnel and the speed of rotation are adjustable, to permit variations and optimization.
