The invention concerns a mobile processing device having a material processing unit, such as a mobile crusher having a crusher unit or a mobile screen having a material screening unit. The mobile processing device comprises a power unit, a frame and a noise encapsulation for the material processing unit. The noise encapsulation is attached to the frame and comprises two cover elements, each of which is pivotable between an open position providing access to the crusher unit and a closed position wherein the cover elements can be interconnected to create an encapsulation for the material processing unit.

To improve operating efficiency of a dry grinding machine, the dry grinding machine includes a rotating shaft; a first blade that is rotationally driven by the rotating shaft; a grinding chamber that houses the first blade; a feed-in section that feeds material to be processed, which is transported by hot wind into the grinding chamber from a direction intersecting the rotating shaft; and a discharging section that is arranged on a side of the first blade opposite the feed-in section, in an axial direction of the rotating shaft, and discharges from the grinding chamber, along with the hot wind, the material to be processed that has been ground by the first blade while being dried by the hot wind fed in from the feed-in section.

A mill includes a generally vertical, rotatable shaft having at least one set of cutter blades driven thereby and a fan assembly mounted on the shaft below the cutter blades in position to receive output therefrom. The fan assembly includes a fan disc secured to the shaft and rotatable therewith. A plurality of fan blades is secured to the fan disc in a generally radial orientation. A terminal portion of the mill includes a gradually, radially expanding outer wall configured in a volute form. The expanded outer wall decreases wear and increases efficiency of discharge and airflow through the mill.

A processing device for processing material to be processed includes a stationary housing with a feed opening for feeding material to be processed and a rotor which is arranged in the stationary housing so as to be rotatable about a vertically extending rotor axis. A plurality of bearing pins is fastened to a base element of the rotor adjacent to the outer circumference of the base element. A processing element is mounted on each of the bearing pins, and the radially outer ends of the processing elements form a processing gap with an inner circumferential wall of the stationary housing. The free ends of the bearing pins are connected to one another via a connecting disc.

A shredder having a substantially tubular casing, which is closed upward by a cover and downward by a base. The shredder also includes a rotating shaft, which is internal and coaxial to the casing, with multiple supporting elements being keyed on the shaft, each element for supporting a number plurality of shredding elements.

The shredding elements have circular trajectories with a circumference that at least partially increases from the upper part toward the lower part of the shredder.
