A mill system for reducing the material size of input material, the system including a plurality of strike plates, preferably of ceramic, embedded within an interior layer of a housing, wherein the interior layer includes tiles made preferably of ceramic; a rotor having one or more rotor blades; a driveshaft; and a motor; wherein the motor powers the drive shaft to rotate the rotor; wherein the rotor blades move input material against the plurality of strike plates.

A device for processing feed material, with a housing enclosing a processing space in which a rotor rotatable about the axis of rotation is arranged. The rotor has a rotor disk at which circumference a plurality of axially disposed impact plates is arranged uniformly distributed. A coaxially arranged processing path surrounds the impact plates while maintaining a working gap. Via a material inlet, the device is fed in the axial direction with feed material centrally ending in the processing space, which upon deflection in the region of the rotor disk is fed in the radial direction to the working gap. To ensure complete and gentle processing of the feed material while maintaining its original taste, smell and color, the processing path is part of a basket rotating about the rotational axis.

A device to fragment solidified bulk material is disclosed. The device comprises a hydraulic motor, a stationary assembly and rotating assemblies, wherein the rotating assemblies includes, a rotational upper whip mount assembly adapted to rotate in a direction, a rotational middle assembly perimeter adapted to rotate in the same direction as the rotational upper whip mount assembly, and a rotational lower whip mount assembly adapted to rotate in a direction opposite the rotational direction of the upper whip mount and middle perimeter assemblies, and a plurality of flails configured to fracture hardened, solidified bulk material while balancing the torque forces to more accurately keep the dual whip-head head in a desired location when operationally engaged with the bulk material.

The invention refers to a comminution device, such as for example a shredder (II) or the like for in particular large-size materials, with a main drive (I) generating a rotational movement for a shredder shaft (2), wherein the rotational speed of the shredder shaft (2) can be changed continuously by means of a gear interposed between main drive (I) and shredder (II), wherein as gear a planetary gear, in particular a planetary superposition gear (1), preferably a hydrostatic superposition gear is provided. The invention is characterized in that the hydraulic engine (4) as additional drive aggregate can be impinged in two different rotational directions.

A material reduction machine includes a prime mover driving a cutting mechanism. A drive system receives a signal to initiate rotation of a cutting mechanism. A sensor senses a machine load parameter and reports a signal to a controller operatively coupled to the clutch to control sequential engagement cycles from the engine to the cutting mechanism. The controller utilizes a stored first disengagement threshold value for stopping a first engagement cycle and continues monitoring the signal as the machine load parameter increases momentarily after reaching the first disengagement threshold. The controller determines and adopts a second disengagement threshold value based on observation of the machine load parameter indicative of maximum load during the continued monitoring after the first disengagement threshold is realized, and further being based on a stored correction factor. The second disengagement threshold value is used for a second engagement cycle.

An impact material processing device has a central impact mechanism arranged to rotate about a rotation axis and at least one stator extending circumferentially about the impact mechanism. Each stator has one or more openings through which material impacted by the impact mechanism can pass. A housing extends about the stator and between an upper plate and a base plate. Each stator is located within the housing and can be moved between a first position and a bypass position. In the first position a lower edge of one or more stator is on the base plate and an upper edge extends to at least an inside surface of the upper plate. In the bypass position the stator is moved to where the lower edge of the stator is lifted from the base plate to form a gap through which material entering the device can flow radially beyond the stator.
