A method and apparatus for grinding a particulate material is disclosed. The method may include providing a system including a roller mill apparatus and a hammermill apparatus, operating the roller mill apparatus and the hammermill apparatus, adjusting a feed rate of particulate material to the roller mill apparatus until power consumption by operation of the roller mill apparatus achieves a target power consumption for the roller mill apparatus, and adjusting a gap between mill rolls of the roller mill apparatus until power consumption by operation of the hammermill apparatus achieves a target power consumption for the hammermill apparatus. The system may include roller and hammermill apparatus with sensing and controlling apparatus configured to operate the roller and hammermill apparatus according to the methods disclosed.

The waste shredding device according to the invention comprises: at least one shredding shaft; an internal combustion engine; a first and a second powertrain between the internal combustion engine and the shredding shaft; at least one energy converter coupled to the internal combustion engine in the first powertrain for converting mechanical energy of the internal combustion engine into storable energy; at least one auxiliary motor supplied with the storable energy in the first powertrain for introducing mechanical energy into the first powertrain; and an energy store for storing at least part of the storable energy and for at least partially supplying the at least one auxiliary motor with the storable energy, in particular for storing storable energy in the event of periods with low power demand and for delivering energy in the event of periods of high power demand.

A shredding device is provided comprising two shredding shafts arranged parallel to each other with shredding elements arranged thereon, wherein the shredding shafts are preferably rotatable mechanically synchronized to each other. A shaft-side coupling element is connected to a respective first end of the shredding shafts. The shredding device includes a housing with a housing-side coupling element is provided that can be coupled to the shaft-side coupling element. The shredding device includes a displacement device enabling displacement of the shredding shafts for decoupling and coupling the shaft-side coupling element from or to the housing-side coupling element.

A canola seed sample crusher features a frame, and a drum rotatably carried on the frame and having an array of seed pockets on an outer periphery thereof. The seed pockets are sized and shaped to receive individual canola seeds respectively therein. A pathway is arranged to receive a length of adhesive tape and guide the tape over the seed pockets in the outer periphery of the drum during rotation thereof to adhesively collect the sample of canola seeds from the seed pockets onto the adhesive tape. A crushing mechanism is carried on the frame and operatively installed at a position along the pathway to crush the sample of canola seeds collected on the adhesive tape during passage of the tap tape through the crushing mechanism.
