Abstract (en)
[origin: CA2430287A1] A device which is suitable for treating mineral material, especially excavat ed material, has two rollers (14, 15) which rotate in opposite directions. Several elements which are used to convey and reduce the material in the eve nt that the particle size is too great are located on said rollers, respectivel y. Particularly brittle and coarse-grained components of the mineral material a re reduced by means of elements (23) which are designed to perform a notching action on particles whose size exceeds a minimum size. Reduction by means of the notching action has been shown to save energy and be less wearing for machines. The elements (23) which perform the notching action can also reduc e wood (tree stumps).
