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.

A pulverizer for reducing a size of input material particles having a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized. The pulverizer also having a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing. The pulverizer also having a housing sidewall having an outer structural wall with a plurality of wall sections. The pulverizer also having canted rotor arms and rotor arms with removable wear pads. An anti-caking device for a vessel such as a pulverizer is also provided.

A non-belt automatic mechanized sampling system for a truck configured to collect materials from a carriage of the truck. The system includes an integrated sample preparation component having, in descending arrangement, a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel. The system also includes a constant mass dividing machine configured to divide the crushed material into samples and discards. The samples are conveyed to a sample retention barrel and discards to a discharging mechanism, which is configured to convey the discards to the carriage.

A rotor locking device in a crusher is arranged for locking a rotational position of a rotor shaft. A shaft engager includes a female toothed mating surface for coaxial engagement with a male mating surface at an end of the rotor shaft to rotationally interlock the same. A fastening portion with engager apertures overlaps with a bearing mount surrounding the rotor shaft so it can be fastened therewith. The engager apertures are circumferentially elongated in order to accommodate alignment with fastening points in the bearing mount, at least when a closest rotational mating position is chosen for alignment. This enables any rotational position of the rotor shaft to be locked for safety before having to access the crusher chamber, especially when the rotor of the crusher has become blocked and requires maintenance.

The mobile waste comminuting device of the invention comprises: at least one comminuting shaft; an internal combustion engine; at least one generator that is coupled to the internal combustion engine to convert mechanical energy supplied by the internal combustion engine into electric energy; at least one electric motor which is powered by the electric energy so as to drive the at least one comminuting shaft and change the direction of rotation thereof; and an energy store for storing energy and at least partly powering the at least one electric motor with electric energy, in particular for storing energy during periods of low power demand and supplying energy during periods of high power demand in relation to the nominal power of the at least one generator.

A method for optimizing a motor load during a shredding process in a shredder for metal materials is provided, wherein the shredder includes a rotor of a mill shredder and a motor with a hydraulic clutch between the rotor and the motor. The method comprises the following steps: measuring a speed of the rotor of the mill using at least one sensor situated on the rotor of the mill; calculating a modified speed based on the measured speed of the rotor, based on a hydraulic sliding of the hydraulic clutch and based on a torque curve of the motor, wherein the torque of the motor is acceptable according to initial calculations within the torque curve of the motor; and applying the modified speed to the motor of the shredder, obtaining the rotational speed that optimizes the motor load during the shredding process.

A machine such as a material processing apparatus comprises a mechanical transmission system coupled to a mechanical load such as a crusher. An internal combustion engine is coupled to the mechanical transmission system, and at least one motor-generator is coupled to an electrical system and to the mechanical transmission system. In at least one mode of operation, the electrical system delivers electrical power to the motor-generator(s), the motor-generator(s) generating mechanical power from the electrical power and delivering the mechanical power to the mechanical transmission system to drive the mechanical load.
