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.

A system processes seeds that are present in crop material. The system includes a first shearing surface, a second shearing surface arranged opposite the first shearing surface, and a clearance between the first shearing surface and the second shearing surface. The system passes crop material between the first and second shearing surfaces, where the crop material contacts the shearing surfaces as it passes through the shearing surfaces. Contact with the first and second shearing surfaces damages seeds that are present in the crop material. The system can be installed in an agricultural harvester to damage seeds that are present in crop residue to prevent the seeds from germinating after the crop residue is discharged from the agricultural harvester back into the field.

Disclosed are grain crushing apparatuses and processes for processing grain. In one embodiment, a grain crushing apparatus includes a first and second sidewall spaced apart from one another a throat dimension in a first direction, and a first and second support shaft positioned transverse to the first and sidewall. The grain crushing apparatus also includes a first and second grain crushing roller. The grain crushing rollers are intermeshed with one another and maintained at positions spaced apart from one another such that they overlap by a distance less than the tooth height. The process is a method for the grown and harvested grain to be shelled, cleaned, stored and then incrementally or iteratively crushed by the shown apparatus or an equal type such that the crushed grain of various sizes may be separated by a sieve and remain as crushed grain with the germ protected uncut, unruptured and intact.

A system and method for flaking. The system includes a stationary roller, and moveable roller, and an adjustable fixator applying tension between the stationary and moveable rollers. The fixator includes a pressure transducer and a linear indicator. The transducer and indicator allow the fixator to read pressures and make fine adjustments to the fixator to obtain a desired gap between the two rollers.

Roller packages (IO) for grinding devices (70), comprising a first roll (11), which is maintained by at least one first bearing body (13), and a second roll (12), which is maintained by at least one second bearing body (14). The first bearing body (13) and the second bearing body (14) are prestressed against each other and comprise stop elements (17,19) with stop surfaces (18, 20), the contact of which counteracts a contact of the rolls (11, 12). The rotational position of the first stop element (17) determines the minimum width of the grinding gap. Also disclosed are grinding devices (70), methods for operating a roll assembly (10) and methods for determining the radial force acting between the rolls (11, 12) of a roll assembly (10).
