Abstract
The invention relates to a multi-roller crusher for the comminuting of mineral mill-feed, whereby the crushing roll are provided with crushing teeth, extending in the circumferential and longitudinal axial directions. Viewed in plan, the crushing teeth are arranged on each crushing roller such that several serial crushing teeth groups are formed behind each other, the imagined connection lines of which run successively at an inclined angle to the plan (1',2′) of each crushing roller outer edge in the direction of the crushing roller centre.
