An impact mill (10) has an inlet (12) for material to enter the mill, an impact mechanism (16, 50) arranged to rotate about a rotation axis and being operable to pulverise the material after entering through the inlet, and an outlet (154) for discharge of pulverised material. Blockage sensors (Bj), vibration sensors V, torque sensors Tn, temperature sensors and proximity sensors may be selectively incorporated into the mill.

Disclosed is a crusher of a crushing machine applied to oleaginous fruits, such as olives and the like. The crusher has a central hub with a central axis and a plurality of hammers connected to the central hub and arranged around the central hub. Each hammer has an outer edge facing a direction opposite to the central hub. The outer edge of each hammer is toothed in such a way that the hammer has at least one recess and two teeth separated by a recess.
