Abstract
A crusher comprises a main shaft a portion of which is disposed in a bore of a rotatable eccentric shaft, the main shaft (1) having a central axis that is inclined with respect to the axis of rotation of the eccentric shaft, and a first crushing head attached to the main shaft and rotatable by the main shaft with respect to a second crushing head so that constrained stroke motion is effected between the first crushing head and the second crushing head. The inclination of the central axis of the main shaft is changed with respect to the axis of rotation of the eccentric shaft by a gear transmission comprising cog wheels, such that the magnitude of the constrained stroke motion changes.
