A mobile firearms pulverizer system is disclosed having a mobile unit having an interior and an exterior, a pulverizer unit having a motor for operating the pulverizer unit with the pulverizer unit being in the interior of the mobile unit, a variable speed motor drive connected to the motor for controlling operation of the motor, a logic control for controlling operation of the variable speed motor drive, and a battery system for providing power to the logic control, the variable speed motor drive, and the motor.

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.

The stationary waste shredding device according to the invention comprises at least one shredding shaft, at least one electric motor for driving the at least one shredding shaft, a mains connection for supplying the stationary waste shredding device with electrical energy and an energy store for storing energy and for at least partially supplying the at least one electric motor with electrical energy, in particular for covering power peaks. Furthermore, the invention provides a corresponding method for operating the stationary waste shredding device.

A material reducing apparatus includes a reducing head that includes a rotary reducing component that carries a plurality of cutters. The reducing head includes a thrown object deflector positioned proximate the rotary reducing component. The thrown object deflector is configured to limit at least one of a distance and a direction that objects can be thrown by the rotary reducing component.

A cone mill comprises a rotating tool for moving friable material across a static conical screen. The tool is driven to rotate by a tool drive shaft. The mill includes a motor, the motor causing rotation of a motor drive shaft. The tool drive shaft and the motor drive shaft are located an angle with respect to each other and the mill comprises a universal joint for transferring rotary motion from the motor through the angle to the tool.

A drive arrangement for driving a work machine includes a motor configured to generate a torque, and a transmission apparatus configured to transmit the torque from the motor to the work machine. The transmission apparatus includes a fluid coupling and at least one controllable torque transmitter configured to control transmission of the torque from the motor to the work machine.

A pulverizer may have such features as an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.

A powder processing apparatus comprising a processing head functionally fixed to a driving unit via a fixation device. The processing head comprises an inlet connecting unit configured to be connected to an input container containing the material to be processed and an outlet connecting unit configured to be connected to an output container destined to receive the processed material. The fixation device comprises a pivoting element configured to rotate the processing head around a pivoting axis by a rotation angle between a first angular position where the material contained in the input container can be inputted in the processing head and where the processed material can be outputted in the output container, and a second angular position where the input container being on a base can be connected to the inlet connecting unit. Also disclosed is a method of using the powder processing apparatus.

A drive device having a main drive device, a gearing, a switchable clutch, at least one hydraulic pump, and a gearing output shaft is started with low wear by providing an auxiliary drive to drive the gearing output shaft independently of the main drive device. A work machine device includes the drive device and a work machine which can be started accordingly in a low-wear manner and which enables longer-term operation in the reverse direction of rotation. Corresponding methods which are also provided in connection with the drive device and the work machine device, enable low-wear starting and the elimination of undesired operating states.
