A planetary roller mill for processing a feed material includes a vessel with a grinding ring having an opening therethrough and a first area. The grinding ring is in sealing engagement with the inside surface of the vessel assembly. At least two non-circular support plates are secured to a rotatable shaft. Each plate has an axially facing surface. A plurality of rollers rotatably are mounted to and positioned between the two support plates. Each of the plurality of rollers are in grinding communication with the grinding surface. The planetary roller mill includes an air supply system having an outlet in communication with the opening in the grinding ring. Areas of the two support plates are of magnitudes which configure a flow area through the opening of at least 30 percent of the first area to provide a predetermined quantity of heated air to remove moisture from the feed material in the grinding assembly.

A road debris collection assembly for includes a vehicle that has a storage tank thereon and an engine. A vacuum unit is coupled to the storage tank and the vacuum unit produces vacuum pressure within the storage tank when the vacuum unit is turned on. A pair of shredding units is each coupled to the vehicle and each of the shredding units has an inlet is aligned with a roadway upon which the vehicle is driving. Moreover, each of the shredding units is in fluid communication with the vacuum unit to suctionally collect debris from the roadway. Each of the shredding units has a plurality of blades therein and the blades in each of the shredding units shredding the debris when the shredding units are turned on.

Embodiments of the present invention pertain to a plant trimming device having a removable cutting cartridge. A direct-drive motor is magnetically coupled to the cutting cartridge. The cutting cartridge houses a blade and a set of rotating blades. Plant parts are cut by the rotating blades across the razor. The cartridge is mounted on rails and has a handle to facilitate the ease of inserting and removing the cutting cartridge. Thereby, an old cutting cartridge is readily removed and replaced by a new cutting cartridge. Furthermore, the cutting cartridge can easily be removed for cleaning and later re-inserted back into the plant trimming device.
