A method of determining wear of a rotary impact crusher includes adjusting the position of an impact rocker relative to an impact rotor with an actuator by a first adjustment value until a crushing section of the impact rocker contacts an impact bar or an impact circle of the impact rotor. The first adjustment value is compared to a first reference value to make a first comparison corresponding to total wear of the impact rocker and the impact bar. The position of the impact rocker is adjusted relative to the impact rotor by a second adjustment value until the impact rocker contacts a reference measurement section. The second adjustment value is compared to a second reference value to make a comparison corresponding to wear of the impact rocker.

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.

The rock crusher has hammers mounted to a rotor and anvils mounted to its casing. First and second anvil sets define a convex surface arrangement facing the rotor and second and third anvil sets define a concave surface arrangement facing the rotor. The anvil sets are oriented to reduce compaction of rocks in the infeed portion of the crusher, and to reduce compaction of aggregate in the casing of the rock crusher. In relation to the movement of each hammer along their work sector, the two operations mentioned above are carried out before a third portion of the work sector wherein rocks are directed to rebound and impact the hammers head-on along the work circle of the hammers. The rock crusher is directly driven by the engine of a potato harvester, wherein the engine, the fan of the harvester and the rock crusher share a common inertia.

Improved free-swinging hammermill hammer configurations are disclosed and described for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The configurations as disclosed incorporate comminution edges having increased hardness for longer operational run times. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. More particularly, a method for replacing hammers and spacers includes pre-assembling hammers, spacers, hammer saddles, locking collars, or any combination thereof and temporarily attaching them to one another before placement onto a hammermill rod. Once placed on the hammermill rod, the temporary attachment is broken such that the hammers within the pre-assembled group may move freely with respect to one another.

A tool for tilling and comminuting in a tool carrier with rotor which is rotatable about the rotor axis, the tool is received in a receptacle of the tool carrier arranged on the rotor. The receptacle is formed by a first face provided in the cutting direction and second face on which the tool is fastened by means of its face which faces away from the cutting direction, the tool has a body which has an end face in the direction of rotation of the rotor and a rear face opposite the end face. The rear face is inclined by 1 to 10 with respect to the end face and the tool is braced and held between the face in the cutting direction of the receptacle and the face of the receptacle that faces away from the cutting direction, play is left between the tool and receptacle base.
